Hydroformed Subframe for Big Block Chevy or Pontiac Engines with Black Powdercoat & Assembly Option

Detroit Speed’s front subframe is a bolt-in replacement for the original stock subframe. It improves the handling and ride quality by utilizing DSE’s unique suspension geometry. It is the ONLY subframe in the aftermarket industry with hydroformed frame rails. The hydroformed frame rails feature strength and stiffness, precise quality and repeatability. Hydroforming preserves the steel’s strength and stiffness because it is performed at low temperatures, unlike traditional high temperature processes which decrease material strength.

The subframe comes complete with the following components: • Hydroformed Framerails • Stamped Crossmembers • Tubular Upper and Lower Control Arms • DSE/JRi Coilover Shocks with 'Detroit Tuned' valving • Torrington Bearings • Coilover Springs • 'Detroit Tuned' Power Rack and Pinion Steering • Splined Anti-Roll Bar • Forged DSE Spindle • Spanner Tool for easy shock adjustments • Composite Anti-Roll bar bushings          

Up to a 10" wide wheel can be packaged without modification to the inner wheel wells. Both the main and secondary crossmembers are stamped for structural rigidity. SBC, BBC, LS1, LS2, and LS7 engines have been designed as a direct bolt-in into this subframe.

The DSE subframe has been designed, engineered, and developed for the road and track. This subframe blends the benefits of current OEM technology and aftermarket performance into one product!

The subframe is available uncoated and unassembled for your SBC, BBC, or LSX engines. We also offer the subframe powdercoated satin black and assembled.

Note: Subframe must ship freight.

Note: Must use at least 17” wheels that require a minimum  inside wheel diameter of 16.250".

Note: For competition  applications, the DSE rack & pinion fluid transfer conversion kit will  replace the hardlines on your DSE rack & pinion using -4 AN steel fittings.  The hoses are Teflon lined to handle the high pressure demands of the steering  system and come with pre-crimped stainless steel fittings to attach to the -4  AN fittings.
