Ksport CHD050-RR Version RR Road Race Coilover Kit

The Ksport Version RR (CHD050-RR) is a purpose-built road race coilover system engineered exclusively for track use. Featuring aggressive spring rates and custom shock valving, this monotube coilover kit delivers maximum handling precision, acute reaction, and unparalleled responsiveness on the circuit. This is a race-use-only system — not intended for street driving.

Key Features:

• 36-Level Damping Adjustment: Simultaneous compression and rebound adjustment via a single knob allows fast, easy fine-tuning of damper response to suit track conditions and driving style
• Monotube High-Pressure Design: Oil and gas are separated within the cylinder for superior heat dissipation, finer damping control, and reduced aeration and cavitation compared to twin-tube designs
• Aggressive Spring Rates & Valving: Spring rates and shock valving are matched as a system — front and rear rated at 18 kg/mm (1,008 lbs/in) — for consistent, predictable performance at the limit
• 20–30mm Shorter Shock Stroke: Stiffer, race-spec shock stroke delivers sharper body control and faster response over OEM-derived designs
• All-Steel Pillowball Upper Mounts: Heavy-duty steel pillowball mounts (on applicable fitments) provide direct, unfiltered driver feedback and increased steering response compared to rubber-isolated OEM mounts
• Camber Adjustment via Pillowball Mount: On compatible applications, camber adjustment is built into the pillowball upper mount — no separate camber kit required
• Adjustable Lower Mount: Ride height adjustability without sacrificing suspension travel, eliminating the ride-quality compromise found in many coilover designs
• 6061-T6 Billet Aluminum Construction: Mounts, collars, and spring perches are CNC-machined from 6061-T6 aluminum for a lightweight, durable, and corrosion-resistant build
• Zinc-Electroplated Steel Shock Body: Protects against rust and environmental wear; kit includes an anti-rust paste packet for additional protection on key coilover areas
• Upgraded Bumpstops: Reinforced bumpstops are integrated inside the dust boot to prevent shock bottoming and resist deterioration
• 12-Month Limited Warranty: Covers manufacturer defects

Spring Rates: Front 18 kg/mm (1,008 lbs/in) | Rear 18 kg/mm (1,008 lbs/in). Ride height lowered approximately 0.5–2.5 inches depending on application. Custom spring rates are available upon request.

For serious road racers who demand a coilover system built from the ground up for competition, the Ksport Version RR CHD050-RR delivers race-proven performance with the adjustability to dial in your setup corner by corner.
