Ksport CHD231-RR Version RR Road Race Coilover Kit Adjustable Monotube - 36-Way

The Ksport CHD231-RR Version RR Road Race Coilover Kit is an purpose-built, track-only suspension system engineered for serious road racing. Featuring aggressive spring rates and precisely matched shock valving, the Version RR delivers maximum handling performance with sharp, immediate response on the circuit. Compared to standard street or sport coilover setups, the Version RR incorporates 30% stiffer spring rates and valving, combined with a 20–30mm shorter shock stroke, optimized specifically for race conditions. For race use only — not recommended for street driving.

Key Features:

• 36-Way Adjustable Damping: Simultaneous compression and rebound adjustment across 36 settings allows precise tuning to match track surface and driving style
• Monotube High-Pressure Design: Oil and gas are separated within the cylinder for superior heat dissipation, finer damping control, and reduced risk of aeration and cavitation versus twin-tube designs
• Steel Pillowball Upper Mounts: Heavy-duty all-steel pillowball top mounts (on applicable applications) provide enhanced strength and direct steering feel and response; on many applications, camber adjustment is built in, eliminating the need for a separate camber kit
• Adjustable Lower Mount: Height is adjusted via the lower mount, preserving full suspension travel — no sacrifice in shock stroke when changing ride height
• 6061-T6 Billet Aluminum Components: Spring perches, locking collars, and upper mounts are machined from aerospace-grade 6061-T6 aluminum for a lightweight, durable, and corrosion-resistant build
• Zinc-Electroplated Steel Shock Bodies: Shock bodies are electroplated with zinc to resist rust and corrosion from the elements
• Upgraded Bump Stops: Reinforced bumpstops are included to prevent shock bottoming over aggressive track surfaces or curbs
• Dust Boots with Integrated Bump Stop: Dust boots protect the damper seal from debris; the bump stop is integrated inside the boot for a compact, durable design less prone to deterioration
• Matched Valving-to-Spring Rate: Each kit is valved specifically to the installed spring rate, ensuring optimal ride quality and long-term reliability
• Custom Spring Rates Available: Standard proven race rates are included, with the option to specify custom rates — shocks will be valved to match your selection
• 12-Month Limited Warranty: Covered against manufacturer defects for 12 months from date of purchase

The Version RR coilover system uses a monotube high-pressure design that keeps oil and gas separated within the shock cylinder. This construction dissipates heat more efficiently than twin-tube designs, reduces oil aeration and cavitation, and enables finer incremental damping adjustments — all critical factors for consistent on-track performance. The combination of race-spec valving, stiffer spring rates, shortened shock stroke, and all-metal pillowball mounts makes the CHD231-RR the definitive choice for competitors demanding every advantage on the road course.
