Ridetech Momentum Chassis Kit Chevy Chevelle 68-72

Ridetech's Momentum Series chassis represents a ground-up performance foundation for the 1968-1972 Chevelle, delivering modern suspension geometry with optimized pickup points. It also improves camber gain, caster, and roll center for sharper handling and greater driver confidence. It maximizes wheel and tire clearance, allowing fitment of wide 18" wheel and tire combinations without sacrificing turning radius or comfort. Rack-and-pinion steering, modular suspension options for coil-overs or ShockWave air systems, and Fox Factory shocks give enthusiasts the flexibility to tune for street cruising, autocross, or track days. With support for a wide range of drivetrains including small- and big-block Chevy, LS, and LT engines, plus compatibility with popular manual and automatic transmissions, the Momentum chassis is a versatile and future-proof platform.
