Ksport CBM402-RR Version RR Road Race Coilover Kit Adjustable Monotube - 36-Way

The Ksport CBM402-RR Version RR Road Race Coilover Kit is an purpose-built track suspension system engineered exclusively for road racing. Featuring stiffer spring rates and aggressive shock valving over standard performance coilovers, combined with a 20–30mm shorter shock stroke, this kit delivers the precise handling response and repeatability demanded by competitive motorsport. For race use only — not recommended for street driving.

Key Features:

• 36-Way Adjustable Damping: Fine-tune compression and rebound simultaneously with 36 individual damping settings, allowing precise setup changes trackside without complex separate adjustments
• Monotube High-Pressure Design: Oil and gas are fully separated within the cylinder, providing faster and more even heat dissipation than twin-tube designs, with finer damping resolution and significantly reduced risk of aeration and cavitation
• Upgraded Shock Bumpstops: Heavy-duty bumpstops are integrated inside the dust boot to prevent shock bottoming on uneven pavement or aggressive track surfaces — more durable and less prone to deterioration than externally mounted designs
• Pillowball Upper Mounts (Select Applications): All-steel heavy-duty pillowball top mounts improve steering feel and driver feedback versus rubber-isolated OEM mounts; Ksport's patented Top Nut and Bearing Kit helps reduce noise at low speeds
• Camber Adjustment (Select Applications): Advanced upper pillowball mounts on many fitments allow independent camber and caster adjustment, eliminating the need for a separate camber kit
• Adjustable Lower Mount: Height adjustment is made via the lower mount on most applications, preserving full suspension travel — unlike designs that sacrifice stroke to achieve ride height reduction
• Aerospace-Grade 6061-T6 Billet Aluminum Components: Mounts, collars, and spring perches are machined from 6061-T6 billet aluminum for a lightweight, corrosion-resistant, and durable construction
• Zinc-Electroplated Steel Shock Bodies: The steel shock cylinders are zinc electroplated for long-term rust and corrosion resistance, even under demanding track conditions
• Spring-Matched Valving: Each kit's shock valving is specifically tuned to match the installed spring rates, ensuring consistent and predictable damping performance; custom spring rates are also available
• Dust Boot with Integrated Bumpstop: Standard dust boots on all units protect the damper seal from contamination and wear

The Version RR system is built to deliver maximum mechanical grip, precise corner entry response, and consistent lap-after-lap performance. Ride height can be lowered 2" to 4.7" depending on application, and custom spring rate options are available for racers who require a tailored setup. Backed by a 12-month limited warranty covering manufacturer defects.
