QA1 63-72 Chevrolet C10 Rear Suspension Conversion System - Firm - Double Adjustable (250lbs/in)
QA1's bolt-on R210-250 rear suspension conversion system upgrades 1963-1972 Chevrolet C10 trucks from factory coil-spring setups to double adjustable coil-overs with 250 lb/in firm springs. This kit delivers up to 6 inches of drop while allowing precise ride height tuning at each corner for ideal stance and performance. Tubular components ensure direct bolt-on installation without removing the truck bed, improving geometry for sharper cornering and stability.
Key Features
- Double Adjustable Coil-Overs: Firm 250 lb/in springs with independent rebound and compression damping adjustments for custom ride control and handling response on street or track.
- Tubular Upper and Lower Control Arms: Integrated pinion angle shims eliminate add-on adjustments and allow exact wheelbase setup for consistent drivetrain performance.
- Adjustable Panhard Bar: Keeps the rear axle centered under the vehicle for predictable handling and reduced body roll during corners.
