DSE Rear Speed Kit 2 - 3 Inch Axle Tubes (043111DS) - 1978-1988 GM G-Body
Put more control into the rear suspension of your GM G-Body with the Detroit Speed Rear Speed Kit 2. Part number 043111DS is engineered for 1978-1988 GM G-Body applications with 3 inch axle tubes, excluding wagons. Rather than simply replacing individual suspension components, Detroit Speed designed this package as an integrated system to help maintain optimum suspension geometry and tire contact throughout the full range of rear suspension travel.
A key part of the 043111DS package is Detroit Speed's patented Swivel-Link rear-link system. The Swivel-Link design allows the rear suspension to fully articulate without binding and without relying on noisy spherical rod ends. It also provides convenient pinion-angle and wheelbase adjustment without requiring the links to be unbolted from the vehicle. Correct pinion-angle adjustment can improve traction while helping reduce driveline vibration. Detroit Speed combines the rear-link system with non-adjustable shocks, 125 pounds per inch springs with a 12 inch free length, and new installation hardware for a performance-focused G-Body rear suspension package.
