Front Suspension Package, Hydroformed Subframe, 5 x 4 3/4 in. Bolt Pattern, Coilover, Chevy, Pontiac, Kit

Detroit Speed hydroformed subframes are bolt-in replacements for the original stock subframe. They're designed to improve the handling and ride quality by utilizing Detroit Speed's unique suspension geometry. These are the only subframes in the aftermarket industry with hydroformed frame rails—which offer strength and stiffness, precise quality, and repeatability. Hydroforming preserves the steel's integrity because it's crafted at low temperatures, unlike traditional high-temperature processes which decrease material strength. Dozens of models are available for vehicles from the 1960s, '70s, and '80s. Order the package recommended for your application.

Detroit Speed hydroformed subframes also include:
• Stamped crossmembers
• Tubular upper and lower control arms
• Coilover shocks with "Detroit Tuned" valving
• Coilover spring
• Power rack and pinion steering
• Splined sway bar
• C6 steering knuckles and bearing packs
