Hey there, it’s Bryan “Bossman” Martin, coming to you from 4 State Trucks in Joplin, Missouri! We’re always on the lookout for innovative and high-quality products that will make our customers’ trucks stand out from the rest. That’s why we recently teamed up with MW Metalworks and their incredible line of lighting fixtures and wire harness covers.

What Sets Them Apart?

MW MetalWork has taken lighting to a whole new level both for the inside and outside of the truck. Their lighting solutions are remarkable due to their construction from high-quality thick billet aluminum. You can easily feel the durability and long-lasting nature of these light fixtures when you hold them in your hand. They truly lead the industry as the Cadillac of lighting due to their superior build and materials.

We’re stocking some more new products here at 4 State Trucks, check out these Sleeper Lights & Wire Harness Covers from the folks over at MW MetalWorks. Join Bryan “Bossman” Martin as he shines the light on these new products we have added to our inventory.

Dome Light Fixtures

MW MetalWorks offers several different dome light options such as a four-light fixture and a single Peterbilt dome light replacement. Both feature glass watermelon-style lenses with billet aluminum bases to give your Peterbilt cab and sleeper lighting a bit of an upgrade.

  • 4 Glass Watermelon Style Sleeper Lights With Billet Aluminum Base
  • Single Glass Watermelon Style Dome Light

Surface Mount Light Fixtures


You can use these glass cab light surface mount fixtures anywhere inside or outside on any vehicle that operates on a 12-volt system. They work great on, trailers, bass boats, or side-by-side as well.

What makes these lights really cool is that they are designed to accommodate any two-inch LED light, giving you the freedom to choose from a wide range of LED brands and colors. The twist feature on the back makes installation simple and the two-inch sealed beam design ensures long-lasting performance.

When you purchase these single glass cab light fixtures, you’ll receive two gaskets, a lens, a stainless bezel, an o-ring, hardware, and a pigtail.

Wire Harness Covers That Are Build To Last

If you own a Peterbilt 379, you’re likely familiar with the hood on the driver’s side firewall of your truck. The main wire harness cover from the factory is made of plastic, but over the course of 10 to 15 years, they tend to split and crack.

However, this particular Peterbilt 379 wire harness cover is different. It is made of thick billet aluminum, specifically designed to withstand the test of time. To further enhance its durability, the aluminum has been powder-coated with a wrinkle finish. With this upgrade, you can expect this wire harness cover to last for decades on the firewall of your Peterbilt.

Where To Purchase

Stop by our location in Joplin to see us in person, give our Parts Pros at 1-888-736-9029, or visit our website at 4statetrucks.com for more information about our billet aluminum lighting products. Be sure to stay tuned for more cool parts in the future!

Breakin’ It Down With Bossman

Being a little nostalgic, we are taking a look back to the late 80s & early 90s when many truck drivers had those “cool” mud flap weights on their trucks. So join us for a blast to the past as we take a closer look at the PeterCar, FreightShaker & KWHOPPER mud flap weights.

The truck industry has come a long way. Back then, semi-trucks weren’t quite the same as they are today. The trucks were cool, but in a different way, with different fashion trends. Having an 18-inch bumper and chicken lights down the bottom of your cabin sleeper, and maybe some 5-inch side straight pipes would have made your truck stand out. There wasn’t a huge selection of bolt-on accessories, trim pieces, and upgrades available like there are today.

Vintage Style Mudflap Plate Weights With Fun Cut Outs

However, we still had unique things to put on our rigs, like the fun mud flap weights with different name cut outs. Do you remember Kwopper, Freightshaker, or Petecarr? Back then you would see these names bolted on everything, such as tool boxes, battery boxes, and hood fenders.

How did these names come to be? It’s hard to say and make sense of those names, but over the years, hundreds of these mud flaps were sold.

KWopper Bottom Mud Flap Plate
Freightshaker Bottom Mud Flap Plate
Petercar Bottom Mud Flap Plate

It’s pretty cool to see how much the trucking industry has evolved. What was cool back then, is still a little cool today.

So, that’s all we have for today’s blast from the past.

Installing Your SH Tubes Shifter Stick

Installing it is pretty simple. You will need to remove the collar of your shift stick and unscrew the shift knob. You will then take off the shift boot and knock out the pin securing the shifter stick. After that, replace your old strick with your new SH tube shifter. Once you reattach everything, you will be good to go.

Keep in mind that if you are going with a taller shifter than the one you took out of your truck, you may need some new airlines and additional brass splices.

Whether you are looking for a round or a square tube shift stick, you can easily find our entire line of SH Tubes Shifter Sticks at 4statetrucks.com. We will be happy to get you fixed up with one of these high-quality polished stainless steel SH Tubes Shifter Sticks.

Finding the Perfect OE Replacement Headlight For Your Classic Peterbilt

All right gang. It’s Brian Martin the Bossman over here at 4 State Trucks. We are talking about Peterbilt headlights. For years the dual round headlight assembly like we used to get on the 359s and even some of the Freightliners back in the day was only to be found in a salvage yard. And that is if you got lucky.

Before now most of us had to settle with an aftermarket version for this headlight. There are several aftermarket parts with a quality stainless steel bucket or even with different bulb choices. However, if you want actual OE quality you will need to look a little harder.

Bossman At 4 State Trucks Talking About Dual Round Headlights For Peterbilt 359s

OE Quality Dual Round Headlight Replacement

Thankfully, the folks at Dirks recently launched an OE-quality aluminum bucket light assembly to factory standards. It has the same quality of headlight buckets, metal work, and bezel that would have come with a new Peterbilt in the 1980s. 

Dirks’ duel round headlight assemblies are made to be of original factory quality. Like the original part, each assembly includes a nice wire loom and bullet connectors on the end. There is a passenger side and a driver side assembly, so make sure you order the parts you need.

Create That Classic Style

We have put a lot of these on drop brackets to install on 389s and 379s. There are many ways to use them when giving your truck a classic style. They look great when installed in some modified Kenworths.

If you are wanting the real deal factory quality headlight that is going to last 12 to 5 years on your truck these Aluminum Dual Round Headlamp Assemblies from Dirks are in stock at 4 State Trucks. They are currently in stock and selling fast. We would love to fix you up with a set. 

Looking for parts for your classic truck or want to give your newer ride a more classic look? We can help at 4 State Trucks or give us a call at 888-875-7787.

Hey folks, Brian Martin the Boss Man here a 4 State Trucks. I am coming to you with Josh Hurley, the head of our BESTfit Engine & Cooling Department. We are excited for today’s conversation about radiators and a truck we all know and love, the 389 Peterbilt.

The factory-installed radiator is one of the major shortfalls of a 389 Peterbilt. It is designed more for light-duty use. So if you are running large horsepower with a heavy load, the stock radiator on this model will probably be insufficient and you will need to trade up for more power.

BESTfit Options

BESTfit offers both an improved stock replacement and a high performance replacement option for a Peterbilt 389 radiator. In the video above, we review both the standard and upgraded options. Look below for a quick overview.

BESTFit Peterbilt 389 Stock Replacement Radiator

BESTfit learned from the manufacturers’ failures and made simple improvements to the design for increased performance. This Peterbilt 389 radiator replacement is similar to the factory-installed part but with a slightly improved structure.

Keep costs down with this BESTfit radiator replacement with built-in improvements. It is typically 30 to 40 percent cheaper than the factory direct options. It is a great choice, especially if what you had before works for your current needs.

Should I Order My Replacement Radiator With A Frame Or Without?

This stock replacement is available with or without a frame. Ordering a stock replacement without a frame can save you $300 to $400. However, ordering a replacement Peterbilt 389 Radiator with a Frame can save a considerable amount of labor hours. If you order the frame already attached, the mechanic can pull out the old radiator and plug in the new one. A built-in frame is especially a great option if the original frame is damaged.

BESTfit Peterbilt 389 Replacement High-Performance Radiator

Looking to gain more power? BESTfit has taken this replacement part to a whole different level and created a new fully-built beast. This high-performance radiator is built with high-grade material and has a strong structure.

Where the stock radiator has two rows, this High-Performance Peterbilt 389 radiator has 4 rows. It can handle heavy loads that the original radiator was not able to. This works great for water trucks, logger trucks, and other heavy-duty applications. Depending on your typical driving conditions, it will last 8 to 10 years.

Does This High-Performance Radiator Fit Other Models?

Your Peterbilt 389 is going to be the most common model this high-performance radiator is going to fit. However, it can also be a great fit for some Kenworth W900 models and the popular Peterbilt 367 logging truck. The Kenworth models have a wide variety of applications and come with different sizes of radiators. For that reason, when placing an order we will need to spec out the OE numbers to ensure fit with this replacement part.

Overview

Are you cost-conscious, on-highway, and just looking for a good option for a replacement radiator? If so, we have you covered with the basic stock replacement plastic aluminum radiator. We also offer it in a fully framed unit that is easy to install. If you are looking for high performance and want to really take care of your engine, we have you covered as well. In that case, the high-performance BESTfit radiator unit with 4 rows will not disappoint.

If you have any questions, contact us at 4 State Trucks and we will get you the answers!

Howdy folks, Brian Martin the Boss Man here a 4 State Trucks. I am coming to you once again with Josh Hurley, our Cooling Department Manager. Today we are going to talk about replacement radiators for Peterbilt 359 models.

Peterbilt 359′ is one of my favorite subject matters. When it comes to big rigs, they are comparable to the automotive icons of 1957 Chevies and 1969 Camaros. If you have a 359 you are probably bound and determined to keep that thing rolling. You are never going to put it out in the weeds and let it just go to rust. You are always going to put that back in service because it is your pride and joy.

Radiator Replacement For Peterbilt 359

Well, let’s talk about radiators because they are extremely hard to find in an aftermarket variety for Peterbilt 359’s. BestFit has teamed up with some of our manufactures to bring you a heavy-duty superior to the original equipment replacement. A lot of technology and effort has gone into building this radiator. It is built with an all-metal brass copper unit and it fits your 359 up through models dating1986.

Upgraded Technology

BestFit is offering 2010-2020 cooling technology in a fitment that will drop right into 1979, 1983, and 1985 trucks. It does however look a little bit different than the factory version produced. This is because we made a few changes to allow more adaptability and to handle up to 1200 horsepower. The core is similar to newer styles found in units before they started being made of plastic and aluminum around the year 2007. It is 40 to 50 percent more efficient than what would have come out factory in the 359.

Do You Offer In A 4 And 5 Row?

Yes, BestFit offers this in a 4-row core and 5-row core high-performance. Both options come with a frame and are available without or with an air cooler to create a cool pack.

Air Cooler Hookups

One of the biggest differences between the original and the replacement is the design on the top of the tank. This addition allows for a charge air cooler without the need to make modifications and can work with multiple arrangements.

Do you have a non-charged air-cooled Cat engine with an aftercooler on top? If so, this aftermarket radiator is equipped with a tank that will work with that arrangement. Do you have a charge air-cooler like that in an 86 model? If so, the tank on this replacement is also notched to where you can use your charged air.

Overall Improvements

BestFit Peterbilt 359 radiator replacements feature steel side rails, steel tanks, and a heavy-duty copper brass core. Most of the early 359’s original radiators have aluminum side rails that eventually bubble and corrode. These original parts came with cast aluminum tanks and aluminum washer bars that kept everything together. Due to the material used and age, they typically crumble and come apart as they are moved.

It is hard to believe that the 359 has been out of production for well over 30 years. So chances are if you are still driving with a stock radiator, it is probably going to be out of service sooner rather than later.

To Sum It Up

This is a very cool part. It is not an item you are going to find at 90% of your truck radiator shops out there. They have kind of written off the 359 and not really pursuing cooling for those models.

Here at 4 State Trucks and BestFit, we are more than excited to work with any of these vintage semi-trucks. We want to keep them on the road, just like you do. All right Peterbilt 359 owners, you heard it here first. If you have any questions or concerns about your radiator and/or fitment feel free to contact us or give us a call at 1-888-875-7787 ext 292.

Today, we are going to talk about Peterbilt 379 radiators. They are one of the most popular trucks we see here at Chrome Shop Mafia. When it comes to radiators there are many options in a wide range of different price points. This is a small overview to help you figure out which radiator you need to order for your Peterbilt 379. 

How Do I Know Which Radiator To Buy?

Not all radiators are created equal, it is not a one-size-fits-all. In the video below, we showcase 3 different options. The major difference between these radiators is the year breaks but some duplication in the model years can cause a bit of confusion. For the Peterbilt 379 models that fall into two different categories, there are a few more details to look at when determining what radiator you need.

Main Differences:

For the older style 1998 to 1994 Peterbilt 379 Models: 

  • Built with Z or L-shaped brackets on the side. This is where your hook cables and spring mount.
  • Mounts offset towards the front.

For 1994 to 2004 Peterbilt 379 Models: 

  • Built with a C channel or a U channel with a single stud on the side.
  • Mounts Offset towards the front.

For 2004 through 2007 Peterbilt 379 Models: 

  • No Tank on Top.
  • There is a remote mounted tank on the firewall.
  • Mounts offset towards the font. Except for the 2006 model.

2006 Peterbilt 359

Something to be aware of; on 2006 models you need to specify your bolt pattern on the bottom of your radiator. It is going to be a center mount instead of an offset mount. All three groups of Peterbilt 379 radiators in the video above mount offset towards the front except for the 2006 models.  Paccar changed to a center mount for this model due to a difference in engine capacity. For that reason, if you mount an off-center mount to a 2006 model you are going to hit your fan blade. We do not want this. So anytime you have a 2006 Peterbilt 379 always let us know so we can hook you up one way or another to the right radiator.  

Do We Offer Radiators In A Stock Replacement 3-Row Core Version?

We offer a wide variety of options, the only radiator we do not offer in a 3 row core version is for the 1998 to1994 models. However, the older style models start with 4 row core options. There are 3-row, 4 row, and 5 row core options available for the newer models.

Does More Rows On A Radiator Mean It is better?

A radiator is made up of tubes that carry the coolant and fins that transfer heat from the tubes to the air passing through the core. Rows are the number of lines of tubes from one face of the core to the other (front to back). Accordingly, more rows mean more tubes which typically means more cooling. A 5 row radiator can effectively produce 33 to 40 percent more cooling than a 3-row radiator put in by the manufacturer.

Hey folks! Brian Martin is here at 4 State Trucks, BestFit aftermarket collision parts. Today we are going to be talking about our line of Alttec fuel tanks for Peterbilt models. 

A Few Facts About Peterbilt Alttec Tanks

How Can I Tell If I Have a New or Old Style Peterbilt Manifold?

Peterbilt changed their manifolds on top of the fuel tank sometime around 2007. Your old-style manifold with all the fittings in line is from 2007 and older. For that reason, the fasted and easiest way to determine the style of your tank is to check if your tank has removable draw tubes.

  • If you can remove the draw tubes from your tank and put them in a new tank, you have an old style manifold.
  • You have the new style of manifold, if your draw tubes are permanently welded in the tank and the fittings on the top are not in line.

Will I Need To Make Modifications?

These Alttec tanks are in a variety of options, so you can find the exact tank you need. They bolt right onto your truck without the need for modifications. The tanks feature a Peterbilt-style neck that will accept the flip top fuel cap. This makes it almost identical to your factory-installed tank.

Cost Savings

Check out our Peterbilt Alttec Tanks. You will find an assortment of 80, 100, 120, 135, and 150-gallon fuel tanks. If you have more questions contact us at 4 State Trucks!
