Detroit Speed Rear Speed 3 Kits 041612DS

The Detroit Speed Rear Speed 3 Kit, part 041612DS, is a rear suspension package meant for classics built between the 1960s and 1980s, built to install alongside a matching Detroit Speed front suspension. It pairs non-adjustable coilover shocks with black-finish coilover springs, rather than treating shocks and springs as separate purchases the way the simpler Rear Speed 2 line does. What the kit includes Besides the non-adjustable coilover shocks and springs, the box holds a black-powdercoated sway bar measuring 1.125 in., trailing arm mount braces, and bushings made from high-durometer black rubber. Installation is described as bolt-on, without welding required. The kit leaves out a third member, axle shafts, air bags, a Watts link, a Panhard bar, rotors, and calipers. Before you order Rear Speed kits are built around a matching Detroit Speed front end, so plan the front and rear together.
