Ksport CSB150-AR Asphalt Rally Spec AR Coilover System 36-Way Damping

The Ksport Rally AR Spec Coilover System (CSB150-AR) is purpose-built for asphalt rally competition, delivering race-grade suspension performance with an extended piston stroke, heavy-duty reinforced internals, and a fully adjustable damping architecture engineered to handle the rigors of competitive motorsport.

Key Features:

• 36-Level Damping Adjustment: Simultaneous compression and rebound adjustment across 36 precise clicks lets you fine-tune handling response and ride characteristics to match course conditions and driver preference.
• High-Pressure Monotube Design: Oil and gas are fully separated within the cylinder for superior heat dissipation, finer damping control, and significantly reduced risk of aeration and cavitation compared to twin-tube designs.
• 6061 Billet Aluminum Construction: Mounts and major structural components are machined from T6-treated 6061 billet aluminum for a lightweight, durable, and corrosion-resistant build.
• Zinc-Electroplated Steel Shock Body: The steel shock body receives a zinc electroplate finish to protect against rust and environmental exposure.
• Matched Spring and Valving: Each kit's valving is specifically tuned to the installed springs, ensuring consistent and reliable ride quality straight out of the box.
• Pillowball Top Mounts (Select Applications): Front and rear pillowball upper mounts preserve OEM suspension geometry while enhancing steering feel, driver feedback, and direct response. Many applications also include integrated camber adjustment, eliminating the need for a separate camber kit.
• Adjustable Lower Mount: Most applications feature an adjustable lower mount for ride height changes that do not sacrifice suspension travel—a critical advantage over fixed-perch coilover designs.
• Rally-Legal Ride Height Range: On supported applications, the system can maintain OEM ride height or lower up to 3 inches from stock—an important consideration for sanctioning body compliance in organized rally competition.
• Rally-Specific Spring Design: Springs are specially engineered for rally driving conditions, providing the compliance and control needed on demanding asphalt stages.

The CSB150-AR is a competition-focused coilover system for drivers who demand precision, durability, and adjustability in a single package. Built to order with CNC-machined components and hand-assembled quality, this system is backed by Ksport's motorsport engineering expertise.
