DSE Rear Speed Kit 3 - Factory GM 10-Bolt - 2-3/4 Inch Axle Tubes (043120DS) - 1978-1988 GM G-Body
Step up to a more complete rear suspension package for your GM G-Body with the Detroit Speed Rear Speed Kit 3. Part number 043120DS is engineered for 1978-1988 GM G-Body applications equipped with the factory GM 10-bolt rear axle and 2-3/4 inch axle tubes, excluding wagons. Detroit Speed designed its Speed Kits as integrated suspension systems that help maintain optimum suspension geometry and tire contact throughout rear suspension travel, giving performance-minded G-Body owners a properly matched combination rather than a collection of unrelated suspension upgrades.
The 043120DS package incorporates Detroit Speed's patented Swivel-Link rear-link technology, which allows the suspension to articulate without binding and eliminates the need for noisy spherical rod ends. The Swivel-Link design also allows pinion angle and wheelbase adjustments without removing the links from the vehicle, making it easier to optimize traction and driveline alignment. Detroit Speed combines the rear-link system with non-adjustable shocks, 175 pounds per inch springs with an 11 inch free length, and the additional performance components that make this a Speed Kit 3 package.
