The Difference

Why Patriot Chassis

Most chassis companies build for 2WD hot rods and pro-touring street cars. We build for the 4x4 community — trucks that need to perform on the trail, the highway, and everywhere in between.

4x4 Specialists

Every product we make is engineered for four-wheel-drive trucks. Not adapted from passenger car parts. Not a Mustang II swap in disguise. Purpose-built 4x4 chassis with 16” front and 15” rear travel.

Patent-Pending Technology

Our Patriot Air Shock is the only patent-pending heavy-duty air shock on the market — 5,000 lb capacity, 22”+ stroke, infinite tunability. We engineered what didn't exist.

Racing-Proven Geometry

Our suspension geometry is drawn directly from Ultra4 desert racing. These aren't catalog numbers — they're hard-won engineering specs proven under the harshest conditions on earth.

Modular Build System

Build your restomod chassis in stages at your own pace — like Legos for adults. Start with a rolling chassis and add IFS, drivetrain, and air suspension when your budget allows.

Fully Engineered

Decades of engineering experience rooted in the racing industry. Our suspension geometry was born from Ultra4 desert racing — proven under the harshest conditions before it ever reaches your truck.

Full CAD & 3D Scanning

Original truck bodies are 3D scanned and every component is modeled in CAD before cutting. The result is bolt-on accuracy that eliminates guesswork and guarantees proper fitment.

Our Story

Built in Idaho.
Driven Everywhere.

Patriot Chassis is a small production shop in Ponderay, Idaho — surrounded by mountains and some of the best off-road terrain in the country. We bring over 40 years of combined engineering experience to every chassis we build. We're not a mass manufacturer — we're a team of engineers and fabricators who share an obsession with classic 4x4 trucks and modern suspension technology.

Every chassis that leaves our shop is built with purpose: to give iconic trucks like the 47-55 Chevy, 58-61 Apache, 67-72 Chevy/GMC, 73-87 Chevy, K5 Blazer, 67-73 Ford, 73-79 Ford, 65-77 Bronco, 78-96 Bronco, and D-Series Power Wagon the performance platform they deserve. We use American-sourced steel, precision CNC machining, and hand-welded craftsmanship to transform ordinary trucks into extraordinary rides.
