Ksport CSB040-AR Rally AR Spec Asphalt Rally Coilover System Damping - 36-Way

The Ksport Rally AR Spec Coilover System (CSB040-AR) is an asphalt rally-purpose-built suspension kit engineered for the demands of competitive asphalt rally racing. Featuring an extended shock stroke and heavy-duty internals, this system is built to stabilize the vehicle and absorb the punishment of uneven road surfaces at competition speeds.

36-Way Damping Adjustment

The system provides 36 levels of damping adjustment, allowing precise fine-tuning for both handling performance and ride comfort. Compression and rebound are adjusted simultaneously via a single knob, making setup changes fast and straightforward during an event.

Monotube High-Pressure Design

Ksport utilizes a monotube shock design with oil and gas separated within the cylinder. Compared to twin-tube designs, the monotube construction dissipates heat more effectively, enables finer damping adjustments, and significantly reduces the likelihood of aeration and cavitation — resulting in more consistent damping performance throughout a stage.

Pillowball Top Mounts

On applicable vehicles, front and rear pillowball top mounts preserve OEM suspension geometry while delivering a more direct, communicative steering feel. On models where camber-adjustable pillowball mounts are available, camber can be set directly from the coilover without the need for a separate camber kit.

Adjustable Lower Mounts & Height Adjustment

Most applications feature an adjustable lower mount design, which allows ride height to be changed without sacrificing suspension travel — a key advantage over traditional threaded-body coilover designs. Depending on application, the system can achieve OEM ride height or lower the vehicle up to 3 inches from stock. Note: many sanctioning bodies in rally competition have minimum ride height rules — confirm your class requirements before setting ride height.

Aerospace-Grade Aluminum & Corrosion Protection

Mounts, collars, and spring perches are machined from 6061-T6 billet aluminum for a lightweight, durable, and rust-resistant construction. Steel shock bodies are electroplated with zinc for additional corrosion resistance. Each kit also includes an anti-rust paste packet for application to key contact areas.

Application-Matched Valving

Spring rates and shock valving are carefully selected and matched for each specific application, ensuring consistent, predictable ride quality right out of the box.
