DSE Hydroformed Front Subframe - Powdercoated - Double-Adjustable Shocks (032015-DDS) - 1970-1981 Chevrolet Camaro / Pontiac Firebird - BBC
Give your second-generation F-Body the chassis and suspension foundation to handle serious Big Block power with the Detroit Speed Hydroformed Front Subframe. DSE 032015-DDS is a bolt-in replacement for the original front subframe, combining hydroformed steel frame rails, Detroit Speed suspension geometry, stamped structural crossmembers, power rack-and-pinion steering, and double-adjustable coilover shocks. Engineered for 1970-1981 Chevrolet Camaro and Pontiac Firebird applications, this system brings modern steering response, suspension control, structural rigidity, and extensive tuning capability to a classic F-Body without sacrificing street manners.
This powdercoated configuration is designed for Big Block Chevy and Big Block Pontiac applications and uses 650 lbs/in springs with an 8-inch spring free length. The double-adjustable shocks provide two independent adjustments and an extensive adjustment range, allowing suspension behavior to be dialed in around the vehicle, driver, and intended use while still delivering excellent ride quality on the street. Hydroformed frame rails provide strength, stiffness, dimensional accuracy, and repeatability, while stamped main and secondary crossmembers reinforce the structure for improved chassis response under acceleration, braking, and hard cornering.
