QA1 R132-200 Rear Coil-Over Suspension System Single Adjustable Ford 9in. 200lb. Springs

The QA1 R132-200 is a complete bolt-in rear coil-over suspension conversion system engineered specifically for 1973–1987 Chevy C10 Squarebody trucks equipped with a Ford 9-inch rear housing. This all-inclusive torque arm suspension system transforms your classic pickup's ride quality, stance, and handling without requiring any welding and without removing the truck bed.

Key Features:

• Torque Arm Design: QA1's unique bolt-in torque arm architecture controls rear axle movement under acceleration, eliminating the binding issues common to other 4-link systems
• Single Adjustable Coil-Over Shocks: Allows tunable damping valving to match your specific ride and handling preferences
• 200 lb./in. Spring Rate (Medium): A balanced medium spring rate delivering a blend of street comfort and performance handling
• 4 to 7 Inches of Rear Drop: Adjustable ride height range of 4"–7" below stock for dialing in the perfect stance
• Ford 9-Inch Housing Compatible: Designed for C10 trucks running a Ford 9-inch rear differential upgrade
• 100% Dyno-Tested Shocks: Each shock absorber is individually dyno tested and serialized for quality assurance
• Complete Kit: Everything needed for installation is included, down to the hardware — no sourcing separate components
• No Welding Required: Full bolt-in installation without cutting, welding, or bed removal
• Made in the USA: All components manufactured at QA1's Lakeville, Minnesota facility

By separating drivetrain forces from suspension movement, the torque arm design allows the springs and shocks to focus exclusively on ride quality and handling. Pair this rear system with QA1's matching front suspension kit for full four-corner ride height adjustability and a perfectly level stance. Backed by QA1's one-year warranty against defects, with a limited lifetime warranty available on select shock absorbers.
