Give your second-generation F-Body a serious chassis and suspension upgrade with the Detroit Speed Hydroformed Front Subframe. DSE 032020DS is a bolt-in replacement for the original stock subframe, combining hydroformed steel frame rails, Detroit Speed suspension geometry, stamped structural crossmembers, coilover suspension, power rack-and-pinion steering, and non-adjustable shocks with Detroit Tuned valving. Engineered for 1970-1981 Chevrolet Camaro and Pontiac Firebird applications using Big Block Chevy or Big Block Pontiac power, this package brings modern suspension control, steering response, chassis rigidity, and road manners to a classic GM platform.
Part number 032020DS is the bare subframe configuration with non-adjustable shocks and 650 lbs/in coilover springs for Big Block applications. The non-adjustable shocks use Detroit Tuned valving to deliver responsive suspension performance without requiring external damping adjustments, making this an excellent choice for builders who want a carefully engineered setup for both street and track use. The hydroformed subframe is supplied bare, giving you control over the final chassis finish, while the control arms and sway bar arms are finished in black powdercoat.
