REBUILD KIT LARGE BODY

The QA1 Rebuild Kit Large Body (model RK13) is a professional-grade seal and bushing replacement assembly designed for high-performance coilover suspension systems and adjustable dampers that demand precision and reliability. This kit is essential for maintaining or rebuilding QA1 large-body shock absorbers, whether for street-tuned muscle cars, autocross competitors, or road-course platforms.

The rebuild kit contains precision-machined seals, o-rings, and internal bushings engineered to OEM specifications for QA1's large-body monotube and dual-tube shock platforms. These components work together to eliminate internal friction variability, maintain consistent oil retention, and restore the damper's ability to respond predictably across compression and rebound cycles.

Street and track builders benefit most from this rebuild kit when refreshing aging suspension systems or performing preventive maintenance on competition vehicles. Its compact size makes it easy to store in your garage or shop cabinet, ensuring that serious enthusiasts have the necessary components to preserve ride quality and suspension geometry under cornering loads or track abuse.
