This QA1 rear coil-over system converts classic Mopar B-Body cars from leaf-spring rear suspension to a triangulated four-link coil-over design. The setup provides a more planted feel, room for larger wheels and tires, wheelbase correction, and clearance for a 3 inch bumper-exit exhaust. Powder-coated tubular components, including the crossmember and upper and lower trailing arms, come with all required hardware. The system works with popular rear axles including the Mopar 8-3/4 inch, Ford 9 inch, and Dana 60. Single-adjustable coil-over shocks allow ride and handling to be fine-tuned and the ride height to be adjusted.
