Return PolicyWith 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 Stock race car build. Rust, accident damage, and more claim these GM Metric chassis frames every day. Our IMCA and USRA Stock Car rules approved GM Metric chassis Stock Car frame is the perfect answer to your next Stock Car 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 Stock Car chassis builders.
Designed in-house at Speedway Motors, these new mild steel frame stubs solve the growing problem of trying to source good used GM Metric chassis frames for your Stock Car builds. These are designed around factory frame dimensions, yet most of the modifications and updates you would have to make to a stock frame are already expertly handled and approved by IMCA and USRA Stock Car 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 Stock Car chassis builders and the alignment holes and dimple stops make welding everything together quick and easy. Start your next Stock Car chassis build with a Speedway Motors frame or use the front or rear stubs to update your current Stock Car build and ditch that twisted, rusty mess of a frame you’re using now.

This frame was delivered faster than estimated. No dings or dents and it looks fresh. Welds look great and no rust. You can definitely tell this wasn't pull out of grandmas backyard. Will update in a few months once car is built how it holds up.

This will be built into a stock car. This frame is definitely not out of your grandmas backyard. Super easy and all parts are there. Will add another review after we've raced it.
