Chassis PartnerA frame swap is exactly what it sounds like — we lift your classic body off its tired factory frame and set it down on a modern, engineered chassis. Three parts, integrated into one seamless foundation.
The result: your car keeps every bit of its vintage character, but underneath it has the geometry, braking, and rigidity of a modern performance car.
Six disciplines, one integrated build. Explore what goes into a StreetWorks chassis swap.
We mount your classic body onto a state-of-the-art aftermarket chassis — Roadster Shop, Art Morrison, or Schwartz Performance — for modern geometry, braking, and steering that transforms how the car drives.
Laser-straight body-to-frame alignment using custom body mounts and bushings, so every panel gap is perfect and the body sits with zero binding or stress on the new chassis.
We modify the classic body's underside to perfectly clear the kick-ups, wider rails, and aggressive geometry of a modern performance chassis — cleanly and structurally, never hacked.
We engineer the swap with pre-planned routes for fuel lines, brake lines, and custom wiring harnesses — keeping the entire undercarriage clean, protected, and safe.
We enhance structural rigidity to handle high-horsepower torque, eliminate body twist, and drastically improve ride quality — so the whole car feels solid and planted.
We install older bodies and unibodies onto newer vehicles — vintage looks on the outside, with a completely modern interior, suspension, and drivetrain underneath. Classic style, modern everything.
Your classic was built for a different era. Here's what a modern chassis changes under the skin.
| Original Factory Frame | Modern Performance Chassis | |
|---|---|---|
| Handling | ✕Vague, body roll, wanders | ✓Flat, planted, pro-touring feel |
| Braking | ✕Weak drums / small discs | ✓Modern big-brake systems |
| Steering | ✕Loose recirculating-ball | ✓Precise rack-and-pinion |
| Ride quality | ✕Harsh & dated | ✓Smooth, modern-tuned |
| Rigidity | ✕Flex, twist & cowl shake | ✓Stiff, solid foundation |
| Horsepower capability | ✕Limited by the frame | ✓Ready for big power |
| Adjustability | ✕Minimal | ✓Ride height & alignment dialed |
