QA1 Mopar Rear Coil-Over Suspension System





Convert your classic Mopar A, B or E Body car from leaf spring rear suspension to a QA1 coil-over kit. The triangulated 4 link design provides a more planted feel and makes room for larger wheels and tires. You can also correct the wheelbase of classic Mopars. The modern design delivers an enhanced driving experience on the street. Plus, it provides the tunability to maximize performance at the autocross, road course and drag strip.

QA1 Mopar rear suspension systems come complete with:

  • Powder-coated tubular components—including the cross member, upper trailing arms and lower trailing arms
  • Lower trailing arm brackets, while allow you to adjust anti-squat characteristics
  • All necessary installation hardware
  • Single-adjustable or double-adjustable shocks to fine tune ride and handling characteristics while easily adjusting the ride height
  • An optional QA1 rear sway bar further enhances handling characteristics and prevents body roll during hard launches
  • Kits work with popular rear axles including Mopar 8 ¾”, Ford 9” and Dana 60 rear ends – choose the appropriate part number when selecting your kit

QA1 systems are made in the USA. Shocks are eligible for an industry-leading Limited Lifetime Warranty.


Fitment Notes
  • Installation requires a small amount of cutting and welding on the frame and axle housing
  • This kit works with factory-located leaf spring mounts or modified inboard-located leaf spring mounts
  • Single-adjustable shocks are recommended for cars used primarily on the street
  • Double-adjustable coil-overs are recommended for cars that will consistently be used for drag racing, autocross or road racing
