Product Details

The Ksport GT Pro Coilover Kit (CSB150-GT) delivers race-proven suspension performance built on the same foundation as Ksport's flagship Kontrol Pro platform — with significant upgrades for improved durability, heat management, and long-term reliability. Featuring large 55mm inverted monotube shock bodies (compared to a standard 20mm design), this kit is engineered for drivers who demand precision handling on both street and track.

Inverted Monotube Design

The inverted front shock design relocates the gas/oil chamber farther away from the knuckle and braking system, dramatically reducing heat transfer and allowing the kit to run significantly cooler under demanding conditions. This layout also lowers unsprung weight, contributing to sharper handling response and improved road feel.

36-Way Adjustable Damping

With 36 discrete levels of damping adjustment, the GT Pro allows precise tuning to match any driving style or road condition. The single-knob adjustment simultaneously alters both compression and rebound damping, making setup changes quick, intuitive, and consistent.

Pillowball Top Mounts

Front and rear pillowball top mounts (on applicable fitments) preserve the factory suspension geometry while delivering a more direct, communicative feel between the driver and road surface. On compatible applications, these mounts also include integrated camber adjustment, eliminating the need for a separate camber kit.

Height Adjustment Without Sacrificing Travel

Most applications feature an adjustable lower mount system, allowing ride height changes without reducing suspension travel — a common drawback of lesser coilover designs.

Key Features:

  • 55mm inverted monotube shock bodies for enhanced heat dissipation and reduced unsprung weight
  • 36-way single-knob damping — adjusts compression and rebound simultaneously
  • Pillowball top mounts front and rear (application dependent) for direct driver feedback
  • Integrated camber adjustment on pillowball mounts where applicable
  • Adjustable spring perch and adjustable body for precise ride height tuning
  • Height adjustment via lower mount — preserves full suspension travel
  • 6061 billet aluminum construction on mounts and key components — lightweight, durable, and corrosion-resistant
  • Steel shock body with zinc electroplating for rust and weather resistance
  • Valving precisely matched to installed spring rates for optimal ride quality
  • Monotube design separates oil and gas for superior heat dissipation vs. twin-tube designs, with reduced aeration and cavitation

The Ksport GT Pro coilover system is an ideal choice for performance enthusiasts seeking a high-quality, fully adjustable suspension upgrade that excels in both everyday driving and track use.
