H&R RSS50420-1 RSS Coilover Kit Height Adjustable Performance Suspension

The H&R RSS50420-1 RSS Coilover Kit is engineered for the performance-minded driver who demands maximum vehicle feedback and precise handling dynamics. Designed and tested on the legendary Nürburgring, this fully adjustable coilover system delivers flat cornering and supreme directional control by lowering the center of gravity and reducing body roll.

Unlike imitation sleeve-over systems, H&R RSS Coil Overs feature a fully threaded shock body paired with H&R's exclusive dynamic damper technology, resulting in a suspension that is purpose-built — not a compromise. The shocks are valved specifically for the matched spring rates to deliver a tight, controlled feel without unnecessary harshness.

Key Features:

• Height adjustable approximately 1.0" – 2.3" on average for a personalized ride height
• Higher spring rates and sport shock valving tuned for spirited driving
• Fully threaded shock body — genuine coilover construction, not a sleeve-over imitation
• H&R exclusive dynamic damper technology for precise suspension response
• Lowers center of gravity and reduces body roll for sharper cornering
• Designed and track-tested at the Nürburgring
• 100% made in Germany
• TÜV tested and approved; meets ISO quality standards

The H&R RSS coilover system represents H&R's highest-performance street coilover line, offering elevated spring rates and more aggressive shock valving compared to standard H&R street coilovers. It is the ideal upgrade for drivers seeking race-inspired suspension performance with real-world street usability.
