Ksport CTY371-RR Version RR Road Race Coilover Kit

The Ksport CTY371-RR Version RR Road Race Coilover Kit is engineered exclusively for competitive road racing. Featuring stiffer spring rates, aggressive shock valving, and a 20–30mm shorter shock stroke, this system delivers the sharp, precise handling demanded by serious track competitors. For race use only — not intended for street driving.

Key Features:

• 36-Way Adjustable Damping: Fine-tune compression and rebound simultaneously with 36 distinct damping settings for precise on-track setup changes.
• Aggressive Spring Rates & Valving: Stiffer-than-stock spring rates and purpose-matched shock valving provide maximum response and handling performance on the circuit.
• 20–30mm Shorter Shock Stroke: Reduced shock stroke is optimized for the lower ride heights and reduced body roll required in road racing applications.
• Upgraded Bumpstops: Reinforced bumpstops prevent shock bottoming over uneven pavement or during aggressive cornering.
• Pillow Ball Upper Mounts: Available on many applications, pillow ball top mounts in the front and rear provide a direct, communicative feel for improved driver response and steering feedback. On select models, camber adjustment is built into the mount — eliminating the need for a separate camber kit.
• Adjustable Lower Mount: Most applications feature an adjustable lower mount for ride height changes without sacrificing suspension travel.
• 6061-T6 Billet Aluminum Construction: Spring perches, locking collars, top mounts, and lower mounts are machined from 6061-T6 billet aluminum for a lightweight, durable, and corrosion-resistant build.
• Zinc Electroplated Steel Shock Body: The steel shock body is electroplated with zinc for added protection against rust and the elements. A complementary anti-rust paste packet is included for application to key areas.
• Monotube High-Pressure Design: Oil and gas are fully separated within the cylinder, enabling faster and more even heat dissipation compared to twin-tube designs. Finer damping adjustability and significantly reduced risk of aeration and cavitation result in consistent, reliable performance lap after lap.
• Matched Valving-to-Spring Rates: Each kit's damping is specifically tuned to the installed spring rates for optimized performance straight out of the box. Custom spring rate options are available.
• Integrated Dust Boot & Bumpstop: Standard dust boots protect the damper seal, with the bumpstop integrated inside the boot for a more durable, long-lasting design.

The Ksport Version RR system carries a 12-month limited warranty covering manufacturer defects. This coilover kit is designed for track and competition use only.
