DSE Hydroformed Front Subframe - Bare - Single-Adjustable Shocks (032020-SDS) - 1970-1981 Chevrolet Camaro / Pontiac Firebird - BBC
Transform the front suspension of your second-generation F-Body with the Detroit Speed Hydroformed Front Subframe. DSE 032020-SDS is a bolt-in replacement for the original stock subframe that combines hydroformed steel frame rails, Detroit Speed suspension geometry, stamped structural crossmembers, tubular control arms, rack-and-pinion steering, and single-adjustable coilover shocks. Engineered for 1970-1981 Chevrolet Camaro and Pontiac Firebird applications using Big Block Chevy or Big Block Pontiac power, this system gives serious street, pro-touring, and track builds the chassis rigidity, steering precision, suspension control, and adjustability needed to put modern handling underneath a classic GM F-Body.
Part number 032020-SDS is the bare subframe configuration with single-adjustable shocks and 650 lbs/in springs for Big Block applications. The shocks combine Detroit Tuned base valving with externally adjustable rebound control, allowing suspension response to be fine-tuned with the turn of a knob while maintaining excellent street ride quality. The hydroformed frame is supplied bare, giving builders control over the final chassis finish, while the upper and lower control arms and anti-roll bar brackets feature a black powdercoated finish.
