Smoky Mountain Rod and Customs

Because we 3D-scanned from a survivor car, every mount, contour, and measurement matches real Tri-Five specs… so it fits your car the way it should without surprises.

It's built with CAD-designed precision, meaning the geometry, suspension angles, and mounting points are engineered intentionally… not eyeballed or modified to "close enough."

All components are laser/plasma cut, ensuring consistent, repeatable accuracy so everything lines up during assembly without grinding, slotting, or forcing parts to fit.

The chassis includes engineered exhaust layouts, so clearance is already accounted for, no guessing, no reworking, and no finding out later that your pipes hit the frame.

You get dedicated client support, which means if you have a question during the build, someone who knows Tri-Fives and this chassis will walk you through it step-by-step.

It's designed specifically for '55-'57 Chevy car builds, so nothing is universal or adapted. Every part of the chassis is shaped around how these cars actually sit, drive, and assemble.

It's made in-house by hot rod builders, not just a mass-production shop. So the people building your chassis understand custom builds, real-world installs, and what matters to Tri-Five owners.

The chassis follows a time-saving build process, meaning many of the complicated steps like alignment, clearances, geometry, fitment are already solved before you ever start your build.

It eliminates hidden retrofit costs, so you're not spending extra on fixing geometry, patching clearance issues, or modifying a stock frame just to make modern parts fit.

You're not just a customer, you're a build partner. We help you choose the right setup, talk through your goals, and make sure the chassis you get is exactly what your build needs.
