DSE SpeedRay Front Suspension Kit - Double Adjustable Shocks - Bolt-In Coilover Mounts (032073-DDS) - 1963-1982 Chevrolet Corvette BBC
Transform the handling, steering response, and front suspension performance of your C2 or C3 Corvette with the Detroit Speed SpeedRay Front Suspension Kit. Engineered specifically for 1963-1982 Chevrolet Corvettes with Big Block Chevrolet engines, part number 032073-DDS combines Detroit Speed's exclusive suspension geometry with bolt-in coilover mounts, quick-ratio power rack and pinion steering, forged aluminum uprights, tubular control arms, and double-adjustable DSE/JRi coilover shocks. This complete system brings modern suspension technology and extensive tuning capability to the classic Corvette platform while maintaining excellent ride quality for street use.
The SpeedRay system is built around a powder-coated bolt-on cradle assembly engineered to improve suspension geometry while providing rigid mounting for the rack and pinion. TIG-welded tubular upper and lower control arms use Delrin bushings, while control arm cross shafts and forged offset upper control arm mounting brackets incorporate caster tuner bushings to optimize suspension geometry. DSE/JRi aluminum-body double-adjustable coilovers feature Detroit Tuned valving and two independent adjustments, providing a wide tuning range to match driver preference and vehicle performance demands. The Big Block configuration uses 650 pounds/inch springs with an 8-inch free length. A splined sway bar with aluminum arms and composite bushings further enhances front-end control, while included Torrington bearings and a spanner tool simplify spring-height adjustments. The Corvette's body and engine do not need to be removed for installation.
