H&R RSS1417-3 RSS Club Sport Coilover Kit - Mono-Tube Gas Shock, Fully Threaded Body

The H&R RSS1417-3 RSS Club Sport Coilover Kit is H&R's most performance-focused street coilover system, purpose-built for drivers who demand flat cornering, supreme directional control, and the ultimate in handling feedback. Designed and tested on the famous Nürburgring, this kit delivers a higher spring rate and firmer shock valving than H&R's Street Performance line — making it the top choice for regular track and club sport participation.

At the core of the RSS system is a mono-tube gas shock construction, which outperforms traditional twin-tube designs by providing stable damping characteristics across all road surfaces while enhancing heat dissipation under sustained performance driving. The shock bodies are constructed from threaded plated steel to minimize unsprung weight, resist corrosion, and support a wide range of ride height adjustment. Paired with special lightweight HF ID race springs crafted from shot-peened 54SiCr6 spring steel, this kit reduces unsprung weight further and sharpens overall suspension response.

Key Features:

• Mono-tube gas shock design for consistent damping and superior heat dissipation
• H&R exclusive dynamic damper technology — responds to changing road and driving conditions automatically
• Fully threaded shock body (not an imitation sleeve-over) for precise, adjustable ride height and corner balancing
• Lightweight HF ID progressive rate race springs made from premium 54SiCr6 shot-peened spring steel
• Higher spring rate and more aggressive shock valving than H&R Street Performance coilovers
• Lowers center of gravity to reduce body roll and improve cornering stability
• Front lowering range: 1.5" – 2.5" | Rear lowering range: 1.0" – 2.0"
• Hand-assembled in Germany to ISO 9001 and German TÜV standards
• 1-year warranty to the original purchaser

Professional installation and a full suspension alignment are recommended after fitting. The H&R RSS1417-3 is the ideal coilover upgrade for the committed motorsport enthusiast who wants the most out of every corner, both on the street and at the track.
