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 & 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 inch 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

Must use at least 17 inch wheels that require a minimum inside wheel diameter of 16.250 inches.

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 in one product.

Base Shock: The DSE/JRi 'Detroit Tuned' base shock is a pure blood pedigree racing shock in its most efficient form as a non-adjustable unit. Although non-adjustable, it shares all the increased dynamic responses of all the JRi adjustable models while providing excellent ride quality on the street.

All sheet metal items must be inspected and signed for as arriving in good condition at time of delivery. Small dings, dents, and scratches are considered to be normal and are easily fixed during the normal filling, priming, and sanding of the item.

If the sheet metal item is damaged during trucking, this must be noted on the Bill of Lading at the time of delivery so that the appropriate action can be taken. Ground Up cannot be held responsible for items damaged in trucking unless this is noted.

Just as original GM body panels, all reproduction sheet metal will require some sanding and bodywork and may require some trimming and shimming before priming. We recommend test fitting all sheet metal before bodywork and paint. We cannot accept returns on sheet metal that has been primed, painted, or installed in any way.
