Why So Many Bolts?

Patriot Chassis is asked this question frequently. We get it, its different, but there are so many reasons why we do this. The following page will explain every aspect of why we use a configurable or modular chassis format.

"Has somebody finally released a modular bolt together chassis? How amazing is that?!" Pirate 4x4

"I was a little skeptical until I started assembling the body to the chassis, exhaust, fuel system, etc... I didn't touch the frame, all installed without welding or drilling and having to recoat!!" Happy Customer

Powder coat!

We powder coat our chassis. Powder coating is one of the strongest coatings you can put on a chassis. As well, one of the most flexible coatings with lots of options. But you can't just powder coat any chassis without running into challenges. One of the most significant challenges is when components are fastened to a frame using rivets or overlapped and welded (like almost every chassis on the market). This creates a void behind and between the fastened or overlapped faces. This creates a electro-static void that makes it difficult or impossible to get powder into these voids. These voids create pockets that once the powder is cured will gather moisture. Powder coat is plastic in powder form that is heated to its melting point to create a plastic coating on the base material. When moisture gets behind the plastic coating it becomes trapped and causes rust that propagates behind the plastic layer and grows over time. There is no stopping it until the entire plastic coating has flaked off. Patriot Chassis powder coats each of the chassis components separately then bolt them together to create a monolithic layer around the component (and frame) that does not have any of these voids. Eliminating these voids eliminate the catalyst to a larger problem. A Patriot Chassis gives your chassis the best chance at a very long life.

Configurable Chassis and Suspension

Is it parallel four link? Or do you want independent front suspension? Maybe double triangulated four link? Or maybe even independent rear suspension? Leaf springs anyone? It doesn't matter what flavor you like because we (or you) can configure your chassis how every YOU like it...simply by bolting them on. We often explain this aspect as Lego's for adults. The base chassis is identical regardless of the suspension types. But you get to configure the chassis to your liking.

Accessorize How You Want

Skid Plates, Dual Exhaust, Single Exhaust, Rock Sliders, Fuel lines, Bumper brackets, electrical, transmission lines, bump stops, sway bars, resi brackets, air system, fuel pumps, extra fuel tanks, air horns, etc... It doesn't matter, we have the accessories you want. And, without disturbing the powder coat, you can add these accessories to the chassis at any time. If you didn't by rock sliders when you purchased your chassis and you decide to add them later, just call us. No drilling through the frame, no welding, no disturbing your coating, just add the accessory.

Customize Your Chassis

If your looking for a platform to build from, start with a Patriot Chassis. We can send you the base frame then you build your own suspension from there. This could be as simple as us cutting weld plates or brackets that you can weld to. Or, send us a sketch and we can design the bracketry or components you need.

Stronger!

Stronger in many ways, but what we didn't expect was how much torsional improvement we would get with the DOM bolt slugs along with the fully boxed frame. To compare torsional rigidity and create a comparative understanding of the improvement, we performed a torsional stress analysis against another well-known chassis, the 2020 F350 Super Duty. The Patriot Chassis frame rail was found to be 1200% more torsionally rigid than the modern Super Duty chassis. This does not include the continuous frame that Patriot Chassis integrates into every chassis. The Patriot Chassis frame tube doesn't just stop at the front and back of the chassis like most chassis; it continues across at the front and back of the chassis, increasing the torsional rigidity beyond the sectional torsional analysis. Why is this important? The round body K5, for example, was designed for 152 horsepower, an incredibly low horsepower compared to modern engines. Most of our full builds see horsepower upwards of 750hp. This significant jump in horsepower is absorbed in the body of the truck. The stresses in the body panels create micro fractures in the paint and filler materials you just spent thousands investing in. These micro fractures allow moisture and salts behind the coating, causing a cancer that continues to grow. Most people think this is a failed coating or paint product, but in reality, it's because the body panels are being overstressed by the engine upgrade. Don't lose your investment to a weak OEM frame. Patriot Chassis can handle well over 2500 horsepower!
