QA1 63-72 Chevrolet C10 Rear Suspension Conversion System - Medium - Single Adjustable (200lbs/in)

Rear suspension system with up to 6" drop for 63-72 C10 trucks. Includes adjustable tubular truck arms, single adjustable shocks, high travel springs, C-notch bracket, panhard bar, and brace bar. QA1's C10 bolt-on rear suspension system is designed to convert trucks originally equipped with a coil-spring rear suspension to coil-overs. This system offers up to 6" of total drop and integrates adjustability into multiple areas so you can truly fine-tune the geometry to create the perfect performance after lowering. , , By converting the coil-spring rear suspension to adjustable coil-overs, the ride height for each corner can be altered for that perfect stance. From there, the tubular steel truck arms feature an integrated pinion angle adjustment, eliminating the need for angled shims and allowing the wheelbase to be set to exact specifications. The adjustable panhard bar keeps the rear centered for more predictable cornering, and the multiple mounting locations correct roll center geometry based on the amount of drop. The coil-overs are also relocated to the outside of the frame rail, closer to the wheel, for better cornering stability and allowing room for popular aftermarket rear-mounted fuel tanks. In addition to being easily bolted on, the entire rear system can be installed without needing to remove the bed of the truck.

Upgrade the rear suspension of your 1963-1972 Chevrolet C10 with the QA1 R110-200 rear coil-over suspension conversion system. Designed for trucks originally equipped with a coil-spring rear suspension, this bolt-on system delivers up to 6 inches of total rear drop while adding adjustability for improved stance, handling, and suspension geometry.

The QA1 R110-200 system includes adjustable tubular truck arms with integrated pinion angle adjustment, eliminating the need for angled shims and helping you set the wheelbase to exact specifications. An adjustable panhard bar keeps the rear axle centered for more predictable cornering, while multiple panhard mounting positions help correct roll center geometry based on the selected ride height. Relocating the coil-over shocks outside the frame rails places them closer to the wheels for enhanced cornering stability and leaves clearance for popular rear-mounted aftermarket fuel tanks.
Installation is simplified with a bolt-in design that can be completed without removing the truck bed. Adjustable ride height allows each corner of the vehicle to be fine-tuned for the desired stance, while adjustable shock valving provides control suited to different driving styles. QA1 engineered this rear suspension conversion system to enhance overall vehicle performance and deliver a precise, customizable driving experience.
