Product Details

The Ksport Version RR (CSB040-RR) is a purpose-built road racing coilover system engineered for maximum track performance. Featuring aggressive spring rates and race-tuned valving, this system delivers acute handling response and precision feedback demanded by competitive motorsport applications. For race use only — not intended for street driving.

Damping & Adjustment:

  • 36 levels of damping adjustment for precise handling fine-tuning
  • Simultaneous compression and rebound adjustment via a single dial for quick, easy setup changes
  • Stiffer spring rates and valving matched specifically to racing applications
  • Spring and valving pairing optimized for unmatched ride quality and reliability on track

Monotube Shock Design:

  • True monotube construction separates oil and gas within the cylinder for superior performance over twin-tube designs
  • Better heat dissipation during extended high-performance use
  • Finer damping adjustability compared to twin-tube alternatives
  • Significantly reduced risk of aeration and cavitation for consistent, predictable damping

Construction & Materials:

  • 6061 billet aluminum mounts and components for a lightweight, durable, and corrosion-resistant build
  • Steel shock body with zinc electroplating for enhanced rust and weather resistance
  • Pillow ball upper mounts (on select applications) for direct driver feedback and improved suspension geometry retention
  • Camber adjustment available via pillow ball mount on certain applications — no separate camber kit required

Height Adjustment:

  • Adjustable lower mount design on most applications allows ride height changes without sacrificing suspension travel
  • 20–30mm shorter shock stroke compared to standard Ksport coilover systems, optimized for lowered race ride heights

The Ksport CSB040-RR is designed for serious road racing competitors who demand precise, repeatable suspension tuning. Built from premium materials with race-proven engineering, this coilover system delivers the performance and durability required at the highest levels of motorsport competition.
