The SL Roadster Difference
What Is a Chassis Swap?
Your classic truck turns heads wherever it goes — but corners like a barge, stops like a freight train, and rumbles at highway speeds. A chassis swap changes all of that without touching the body you love.
We remove the original frame and replace it with a purpose-built, modern chassis — engineered specifically for your year and model. What you get is a vehicle that looks exactly like it did in 1965, but drives like it rolled out of a factory today.
4-Wheel Disc Brakes
From drum brakes to modern 4-wheel discs. Stop with confidence — the kind your family deserves.
Drivetrain Options
Keep your original powertrain, swap in a modern LS, or go full restomod. The chassis supports it all.
Rack-and-Pinion Steering
Precise, responsive steering that actually goes where you point it — no more wrestling the wheel.
Bolt-In Chassis Series
SPEC & OBS Series
We work with two purpose-built chassis platforms, each engineered for specific vehicle families. Both are bolt-in solutions — designed to work with your original body mounts and firewall, not against them.
