    Convert your classic Dodge Charger, Dodge Challenger, and Plymouth Barracuda from torsion bar suspension to a QA1 coil-over system. Kits include a tubular K member for reduced weight and room for big-tube headers. Modular motor mounts offer many engine options-including Gen 3 Hemis. Systems easily bolt-in without any cutting or welding. QA1 tubular control arms and rack-and-pinion steering greatly improve drivability and performance while providing a modern feel. Kits include single- or double-adjustable QA1 coil-overs to easily dial in your preferred ride quality and ride height. Optional MOD Series shocks provide peak performance on the track and drag strip. Kits are available in drag or handling configurations. Drag kits use rod ends on both upper and lower control arms to improve weight transfer by reducing deflection. They include a lighter spring rate to improve rear grip during hard launches. Drag kits offer 0"-2" of drop. Handling kits use poly bushings on lower control arms to provide improved cornering and reduced NVH. They incorporate a heavier spring rate for increased front-end stability. Handling kits are available with 0"-2" or 2"-4" of drop. Both kits can be paired with an optional QA1 front sway bar. QA1 systems are made in the USA. Single- and double-adjustable shocks are eligible for a Limited Lifetime Warranty. Fitment notes: Single-adjustable shocks are recommended for cars used primarily on the street. Double-adjustable coil-overs are recommended for consistent drag racing, autocross or road racing. MOD Series shocks are recommended for maximum tunability and higher force curves. Gen 3 Hemi power steering pumps require a pressure reducer and the installation of a power steering cooler. Coil-overs and control arms in this kit can NOT be used with other QA1 tubular products designed for torsion bar suspension. Kits use Mustang II spindles for plenty of brake options. Kits with 2"-4" of drop require wheels to be least 18" in diameter.
