The DSE Speed Kit 1 is designed to lower the ride height of your 1967-1972 GM C10 truck by 5 to 6-inches in the rear. The Speed Kit 1 features lowering springs, lowering shocks, frame notch, and track bar/shock relocation for a complete rear lowering solution. Detroit Speed coil springs lower your truck by 5.5-inches while improving the ride quality and handling. Lowering shocks and relocation improve the shocks' ability to control the rear axle. The unique frame notch bracket provides the necessary clearance when lowering your truck and improves chassis rigidity. The adjustable track bar, featuring dual-axis pivot bushings, is relocated to improve stability and allow centering of the rear axle after lowering.

Fits 1967-1972 C10 with factory truck arms and coil spring rear suspension only. This suspension system will also work for some 1967-1972 GMC C15 trucks, but only if it had the factory optional truck arm and coil spring rear suspension. This suspension system does not fit trucks with leaf spring rear suspension since the frame is different. Basic Fabrication Skills required: Measuring, Cutting, Drilling The track bar location allows 3" exhaust to be routed above the track bar on the passenger's side. Factory style differential cover is required to provide clearance for both the differential and the exhaust. Oversize aluminum differential covers do not provide required clearance.
