QA1 68-70 Mopar B-Body Rear Coil-Over Conversion Kit , Convert your classic Charger, Belvedere, Coronet, GTX or other Mopar B-Body 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. The MOD Series shocks provide peak performance on the track and drag strip, delivering the aggressive force curves required for top-tier pro touring and drag racing cars. These shocks maximize tunability with modular valve packs. You can dramatically change your valving in minutes without ever taking the shock off the car, losing/contaminating oil or worrying about your nitrogen charge. 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. , , 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.
