Ksport CAU431-AR Asphalt Rally Spec AR Coilover Kit Damping Monotube - 36-Way

The Ksport Rally AR Spec (CAU431-AR) coilover system is an competition-grade suspension kit engineered from the ground up for asphalt rally racing. Featuring extended stroke geometry, heavy-duty internals, and large-diameter pistons for added oil capacity, this system is built to perform under the demands of competitive motorsport while offering a refined level of tunability for the serious driver.

36-Way Simultaneous Damping Adjustment

With 36 levels of damping adjustment, the Rally AR Spec allows precise tuning of both compression and rebound with a single adjustment — saving valuable time during setup without sacrificing performance. Spring valving is individually matched to each application's installed springs for consistent, predictable handling and long-term reliability.

Monotube High-Pressure Design

Unlike twin-tube designs, the Ksport monotube shock separates oil and gas within the cylinder. This architecture dissipates heat faster and more evenly, enables finer damping calibration, and significantly reduces the risk of aeration and cavitation — resulting in more consistent performance lap after lap.

Key Features:

• 36-way damping adjustment — simultaneous compression and rebound tuning in a single knob
• Extended stroke design with heavy-duty internal components built for competition use
• Monotube construction with separated oil and gas chambers for superior heat dissipation
• Large-diameter pistons for increased oil capacity and improved cooling efficiency
• 6061 billet aluminum construction on mounts and major components — lightweight, durable, and corrosion-resistant
• Zinc electroplated steel shock bodies for rust and element resistance; includes anti-rust paste packet for additional protection
• Pillowball top mounts (on applicable fitments) for direct steering feel, improved driver response, and OEM-spec geometry
• Integrated camber adjustment on pillowball top mounts (where applicable) — eliminates the need for a separate camber kit
• Adjustable lower mount on most applications for ride height adjustment without sacrificing suspension travel
• Application-matched spring valving for optimized ride quality and reliability

Ride Height Notes: On many applications, the Rally AR Spec system can achieve OEM ride height or lower up to 3 inches from stock depending on fitment. Competitors should verify ride height compliance with the rules of their sanctioning body prior to installation.
