QA1 front coil-over conversion systems replace the factory torsion bar front suspension on classic Dodge and Plymouth B-Body and E-Body cars with a modern coil-over setup. The system uses a tubular K-member that reduces weight and clears big-tube headers, along with modular motor mounts that support many engine options including Gen III Hemi power. Tubular control arms and rack-and-pinion steering improve drivability and handling, and the kits bolt in without cutting or welding. Mustang II spindles are used for a wide range of brake options. QA1 systems are made in the USA.
