H&R RSS1851-1 RSS Coilover Kit Height Adjustable Performance Suspension

The H&R RSS1851-1 RSS Coilover Kit is engineered for the performance-minded driver who demands maximum vehicle feedback and precise handling. Designed and tested on the legendary Nürburgring, this coilover system delivers flat cornering and supreme directional control by lowering the center of gravity and significantly reducing body roll.

Built as a true coilover system — not an imitation sleeve-over — the RSS features a fully threaded shock body that allows the spring perch to be raised or lowered independently for precise ride height adjustment. H&R's exclusive dynamic damper technology delivers stiffer spring rates and more aggressive shock valving compared to standard H&R coilovers, making the RSS the firmest street coilover in the H&R lineup and an ideal choice for weekend track and club sport use.

All H&R components are hand-assembled in Germany under strict ISO 9001 and German TÜV quality standards, ensuring consistent performance and long-term durability. Note: This application fits vehicles with a 55mm front strut clamp and multi-link rear suspension only.
