The Roadster Shop SPEC Series chassis is a modern bolt-on upgrade for 1955-1957 Chevy Tri-Five models. It’s one of the lightest, strongest, and easiest-to-install complete systems, with CNC-laser-cut, MIG-welded rails and factory mounts for true plug-and-play fitment—no major body mods needed. It features proprietary independent front suspension with power rack-and-pinion steering, Wilwood Pro Spindles, and parallel 4-bar rear with Ford 9" housing and 31-spline axles for superior handling, ride quality, and rigidity. Paired with a Southern Performance Systems turnkey LS3 package (e.g., Street Rod at ~$22,315, dyno-tuned with 4L70E trans), it delivers effortless torque, street drivability, and 560+ hp potential—transforming your classic into a high-performance Pro Touring evolution.
Other models available in Camaro, Corvette, Impala, GTO, and more.
