The new Detroit Speed C2/C3 SPEEDRAY front suspension has no compromises and exclusive suspension geometry for superior handling and ride quality. Available as a 100% bolt-on system or with a small amount of fabrication for a competition coilover option that allows faster spring changes.

The SPEEDRAY system features Detroit Tuned quick ratio power rack and pinion steering along with forged in the USA Detroit Speed aluminum uprights. The bolt-on powder coated cradle assembly improves suspension geometry, provides rigid mounting for the rack and pinion, and includes integrated tie down eyelets. DSE/JRi "Detroit Tuned" Coilover shocks/springs allow for spring rate tuning and ride height adjustment. It also includes a splined sway bar with aluminum arms, composite bushings, powder coated tubular upper and lower control arms with Delrin bushings, forged offset upper control arm mounting brackets with caster tuner bushings to optimize suspension geometry while providing clearance for Gen V LT4 engines. The kit also includes Torrington bearings and a spanner tool for easy spring height adjustments.

This SPEEDRAY kit is designed for 1963-1982 Big Block Corvettes. Fabricated system requires cutting upper shock tower and welding upper coilover mount bracket (see instructions). Kit features single-adjustable shock and 650lb coil-over springs.

The DSE/JRi racing shock includes all features of base shock with "Detroit Tuned" valving plus installed rebound adjustment with the simple turn of a knob while providing excellent ride quality on the street.
