QA1 62-72 Mopar B Body/70-74 E Body Front Double Adjustable Coilover System

Mopar, 66-72 70-74 B/E-Body, Double Adjustable, 400 Lb/In 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.

Upgrade the front suspension of your classic Mopar with the QA1 qap52347-D400 double-adjustable coil-over system. Designed for select 1966-1972 B-body and 1970-1974 E-body vehicles, this complete system replaces the original torsion bar suspension with a modern coil-over setup that improves ride quality, handling, adjustability, and overall drivability. It is well suited for Dodge Charger, Dodge Challenger, Plymouth Barracuda, and other compatible Mopar applications.

The system includes a lightweight tubular K-member with clearance for large-tube headers, modular motor mounts for a wide range of engine options, QA1 tubular control arms, rack-and-pinion steering, and double-adjustable QA1 coil-over shocks. The suspension bolts in without cutting or welding and provides adjustable ride height along with independent compression and rebound tuning. Double-adjustable shocks are recommended for consistent drag racing, autocross, and road racing, while optional MOD Series shocks are available for maximum tuning capability and higher force curves.

This configuration uses a handling-oriented design with poly bushings on the lower control arms to improve cornering response while helping reduce noise, vibration, and harshness. Kits are available with different drop ranges, and the applicable configuration supports a 0-2 inch or 2-4 inch drop depending on the selected setup. Systems with a 2-4 inch drop require wheels at least 18 inches in diameter. The kit uses Mustang II spindles, allowing numerous brake upgrade options, and it may be paired with an optional QA1 front sway bar.

QA1 manufactures this suspension system in the USA and backs its single- and double-adjustable shocks with a Limited Lifetime Warranty. Gen 3 Hemi power steering pumps require a pressure reducer and power steering cooler. Coil-overs and control arms included with this kit cannot be combined with other QA1 tubular products designed for torsion bar suspension. Verify vehicle application and suspension configuration before installation.
