This QA1 front suspension system converts a 1967-1976 Mopar A-Body from torsion-bar suspension to a QA1 coil-over setup. The kit uses a tubular K-member to reduce weight and open up room for big-tube headers, and modular motor mounts support a wide range of engine options including the Gen III Hemi. The system is a bolt-in design and provides a 0-2 in. drop with single-adjustable shocks and 400 lb/in. springs.
