Don’t Build Your Next Dirt Racing Car With a 30+ Year-Old G-Body Frame

With the last production GM Metric chassis frame hitting the road in 1988 it is no doubt getting tougher to find a suitable chassis for a competitive race car build. Rust, accident damage, and more claim these GM Metric chassis frames every day. Our IMCA-approved GM Metric chassis Stock Car & Hobby Stock G-Body frame rails are the perfect answer to your next chassis build! It is available as a weld together front frame stub (with midframe rails included), weld together rear frame stub, or complete weld together frame kit (front stub, rear stub, and midframe rails), perfect for chassis builders.

Designed in-house at Speedway Motors, these new mild steel GM G-Body frame stubs solve the growing problem of trying to source good used GM Metric chassis frames for your dirt racing car. These are designed around factory frame dimensions, yet most of the modifications and updates you would have to make to a stock G-Body frame are already expertly handled and legal per IMCA rules. This includes shortened front and rear frame horns, front crossmember “duckbill” removed for additional steering linkage clearance, and much more! Final assembly and welding are all that is required for G-Body chassis builders and the alignment holes and dimple stops make welding everything together quick and easy. Start your next chassis build with a Speedway Motors frame or use the front or rear stubs to update your current chassis and ditch that twisted, rusty mess of a frame you’re using now.
