QA1 Rear Coil-Over Conversion System – Medium – Double Adjustable (200 lb/in) for 1963-1972 Chevrolet C10
The QA1 RCK52616 Rear Coil-Over Conversion System is the ultimate performance upgrade for your 1963-1972 Chevrolet C10. This complete bolt-on kit replaces the factory leaf springs with modern QA1 double-adjustable coil-overs featuring 200 lb/in springs (medium rate), giving you 2.5″ to 5.5″ of adjustable ride height, vastly improved ride quality, and superior handling. With independent compression and rebound adjustment, you can fine-tune the suspension for daily driving, cruising, or aggressive cornering while dramatically reducing unsprung weight and eliminating the harsh ride of stock leaf springs.
