QA1 Four Link Conversions R156-170

QA1's R156-170 four-link conversion swaps a leaf-spring rear end for a triangulated setup, using a 170 lbs./in. coilover spring on a single adjustable shock, so there is one dial for damping rather than separate compression and rebound control. The upper trailing arms are double adjustable and the lowers are single adjustable, all finished black powdercoat. QA1 calls for welding on this install. What to check before buying Plan for fabrication work rather than an afternoon bolt-in, since the welding QA1 specifies means this is not a simple swap for someone without that capability or a shop lined up. A spanner wrench for the coilover ships with the kit. What comes with it The package includes spherical bearing bushings and the trailing arm mount braces, plus mounting hardware for the arms and shocks; a sway bar, watts link, panhard bar, and brake components are not included. Does this kit include a sway bar? No, a sway bar is not part of this four-link conversion. Is welding needed to install it? Yes, QA1 lists welding as required for this four-link kit.
