DSE Hydroformed Front Subframe - Bare - Single-Adjustable Shocks (032018-SDS) - 1967-1969 Camaro / Firebird / 1968-1974 Nova - BBC
Give your Big Block-powered classic GM the suspension foundation to put its horsepower to work with the Detroit Speed Hydroformed Front Subframe. DSE 032018-SDS is a bolt-in replacement for the original stock subframe that combines hydroformed steel frame rails, optimized Detroit Speed suspension and steering geometry, stamped structural crossmembers, power rack-and-pinion steering, a splined sway bar, and single-adjustable coilover shocks. Engineered for serious street, pro-touring, and track builds, this system delivers the chassis rigidity, steering precision, grip, and suspension control needed to transform the way a classic F-Body or X-Body drives.
Part number 032018-SDS is the bare subframe configuration for Big Block Chevy applications and uses 650 lbs/in coilover springs. The single-adjustable 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. Hydroformed frame rails provide high strength, stiffness, dimensional accuracy, and repeatability, while stamped main and secondary crossmembers reinforce the assembly. The bare subframe also gives builders flexibility when selecting the final chassis finish.
