1967 - 1969 Firebird Detroit Speed Subframe Kit, DSE Hydroformed, Powder Coated and Assembled

Detroit Speed’s all new front subframe for 67, 68 and 69 Firebird 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 reliability. Hydroforming preserves the steel’s strength and stiffness because it is performed at low temperatures, unlike traditional high temperature processes which decrease material strength. 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!

This is the Powder Coated and Assembled. Frames come SATIN BLACK powder coated.

The DSE front frame has the following features:

Hydroformed framerails and stamped crossmembers
Optimized suspension and steering geometry
Ability to accommodate small and big block Chevrolet engines as well as LS1, LS2, and LS7 engines
Fits within stock inner fenders on a 1969 Firebird without modifications. 1967-1968 Firebirds may require modifications to the inner fenders.
