Product Overview
Convert your classic Dodge Charger, Dodge Coronet, and and Plymouth Belvedere from leaf spring rear suspension to a QA1 coil-over kit that uses a triangulated 4 link design. This is the best way to gain a more planted feel, make room for larger wheels and tires and correct the wheelbase of classic Mopars. The kit allows you to run a 3" bumper exit exhaust. This modern design instantly delivers a more modern driving experience on the street while giving you the adjustability 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-and all installation necessary hardware. Kits work with popular rear axles including Mopar 8 3/4", Ford 9" and Dana 60 rear ends. Choose the appropriate part number when selecting your kit. Each system includes your choice of single-adjustable, double-adjustable or MOD Series shocks. All of the coil-over options give you the ability to fine tune ride and handling characteristics. You can also easily adjust the ride height to achieve the look and performance you want. QA1 coil-over rear suspension systems can be paired with an optional QA1 sway bar to further enhance handling characteristics and prevent body roll during hard launches. QA1 systems are made in the USA. Single- and double-adjustable 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. MOD Series shocks are recommended for drivers who want maximum performance out of their vehicle.
