Ksport CMZ241-RR Version RR Road Race Coilover Kit

The Ksport CMZ241-RR Version RR Road Race Coilover Kit is an aggressive, track-focused suspension system engineered exclusively for road racing competition. With stiffer spring rates, performance-matched valving, and a 20–30mm shorter shock stroke, this kit is purpose-built to maximize cornering response, handling precision, and on-track consistency. This system is intended for race use only and is not recommended for street driving.

Key Features:

• 36-Way Adjustable Damping: Simultaneous compression and rebound adjustment across 36 distinct settings allows precise tuning of the suspension to suit specific track conditions and driving styles.
• Race-Tuned Spring Rates & Valving: Aggressive spring rates and shock valving are matched to each other at the factory, delivering unmatched consistency and predictable handling at the limit. Custom spring rate options are available.
• 20–30mm Shorter Shock Stroke: The reduced shock stroke keeps the suspension in its optimal working range for road racing applications, improving cornering geometry and response.
• Upgraded Bump Stops: Heavy-duty bumpstops are included to prevent the shock from bottoming out over uneven pavement or harsh track conditions.
• Monotube High-Pressure Design: Oil and gas are separated within the cylinder for superior heat dissipation compared to twin-tube designs. This construction minimizes aeration and cavitation, resulting in more consistent damping performance throughout a race session.
• Pillow Ball Upper Mounts (Select Applications): Front and rear pillow ball top mounts provide a direct, responsive feel while maintaining proper suspension geometry. A patented Top Nut and Bearing Kit helps reduce noise during low-speed steering inputs.
• Camber Adjustment (Select Applications): The advanced upper pillow ball mount offers integrated camber adjustment on many fitments, eliminating the need for a separate camber kit.
• Adjustable Lower Mount: Height can be adjusted without sacrificing suspension travel — a common drawback of lesser coilover designs.
• 6061-T6 Billet Aluminum Construction: Mounts, collars, and spring perches 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 to resist rust and protect against the elements. An anti-rust paste packet is included for additional protection on critical areas.
• 12-Month Limited Warranty: Covers manufacturer defects from the date of purchase.
