Product Details

The Ksport CBM140-KP Kontrol Pro is a fully adjustable coilover kit engineered to deliver professional-grade suspension performance for both street driving and track use. Built around a high-pressure monotube shock design, this system separates oil and gas within the cylinder for faster, more even heat dissipation compared to twin-tube construction — reducing aeration and cavitation for a consistently smooth, responsive ride.

At the heart of the Kontrol Pro system is its 36-way adjustable damping, which simultaneously alters compression and rebound with a single adjustment. This makes dialing in your preferred setup fast and intuitive, whether you're tuning for maximum grip on the track or a comfortable daily driving experience.

The kit features an adjustable lower mount design that allows ride height to be set independently of suspension travel — a key advantage over many competing coilover systems that sacrifice travel when the vehicle is lowered. Included pillowball top mounts allow installation to OEM geometry specifications while also enhancing steering feel and response. On applicable configurations, the upper pillowball mounts provide integrated camber adjustment, eliminating the need for a separate camber kit. Advanced upper mount configurations on select applications support independent camber and caster adjustment for the most precise alignment tuning.

Key Features:

  • 36-Way Adjustable Damping — simultaneous compression and rebound adjustment in a single knob
  • Monotube High-Pressure Design — oil and gas separated within the cylinder for superior heat management and consistent damping
  • Adjustable Lower Mounts — height adjustability without sacrificing suspension travel
  • Pillowball Top Mounts Included — front pillowball upper mount; rear aluminum top mount
  • Integrated Camber Adjustment — available on front upper mount, no separate camber kit required
  • 6061-T6 Billet Aluminum Construction — mounts, collars, and spring perches are lightweight, durable, and corrosion resistant
  • Zinc Electroplated Steel Shock Bodies — protects against rust and environmental exposure
  • Matched Valving and Spring Rates — front 9 kg/mm (504 lbs/in), rear 6.5 kg/mm (364 lbs/in), tuned together for balanced ride quality and reliability
  • Designed with professional road racing performance standards in mind

All Ksport components are CNC machined and hand-assembled to tight tolerances, with each batch undergoing leak testing, balancing, and corrosive environmental simulation before shipment. The Kontrol Pro system delivers an exceptional combination of precision engineering and real-world value for enthusiasts seeking a high-performance suspension upgrade.
