Product Details

The Ksport GT Pro Damper System (CSB090-GT) represents a flagship-level coilover solution built around an inverted 55mm monotube shock body design. By inverting the shock, the gas/oil chamber is positioned farther away from the knuckle and braking components, reducing heat transfer to the damper fluid for more consistent performance. The inverted configuration also reduces unsprung weight, contributing to sharper handling response and improved road feel.

At the core of the GT Pro system is a true monotube design, where oil and gas are separated within a single cylinder. Compared to twin-tube designs, the monotube configuration dissipates heat more effectively, enables finer damping adjustments, and virtually eliminates the aeration and cavitation that can degrade ride quality under hard use.

Key Features:

  • 36-way adjustable damping — simultaneously adjusts compression and rebound for simplified, precise tuning to match driving style and conditions
  • Inverted 55mm monotube shock bodies — reduces unsprung weight and heat transfer from brake and knuckle components
  • Metal pillowball top mounts — front and rear (application dependent) preserve OEM suspension geometry while delivering a more direct, responsive driver feel
  • Camber adjustability integrated into pillowball top mounts — allows camber correction directly from the coilover without a separate camber kit (on applicable fitments)
  • Adjustable lower mount / spring perch — ride height is adjustable without sacrificing suspension travel, unlike traditional sleeve-type designs
  • 6061 billet aluminum construction on mounts and major components — lightweight, corrosion-resistant, and highly durable
  • Zinc electroplated steel shock bodies — provides long-term protection against rust and environmental exposure
  • Valving matched to installed springs — each kit is tuned from the factory to work in harmony with the included spring rates for optimal ride quality and reliability

The Ksport GT Pro CSB090-GT is engineered for enthusiasts who demand both track-capable performance and street usability. The combination of adjustable body height, matched valving, and precision aluminum components makes this system a comprehensive, high-performance suspension upgrade.
