Product Details

The Ksport Version DR Coilover Kit (CMZ140-DR) is purpose-built for drag racing, engineered from the ground up to reduce elapsed times (E.T.) and improve 60-foot times. Built upon Ksport's proven Version RR coilover platform, the Version DR features internal modifications specifically tailored to withstand the demanding conditions of drag strip competition.

Each kit is custom valved for drag racing, with spring rates carefully selected to maximize traction and precisely regulate weight transfer at launch. Ksport engineers each DR kit differently based on drivetrain configuration — FWD, RWD, or AWD — ensuring optimal launch characteristics for your specific application. Not intended for street or daily driving use.

Key Features:

  • 36 levels of damping adjustment for precise tuning of suspension behavior on the strip
  • Monotube shock construction for superior heat dissipation, finer damping adjustability, and more consistent performance compared to twin-tube designs
  • Pillowball upper mounts available on many McPherson strut applications, improving steering feel, response, and feedback
  • Patented pillowball bearing design engineered to minimize noise during steering inputs
  • Custom spring rates and shock valving optimized for weight transfer management during hard launches
  • FWD / RWD / AWD specific tuning — each kit configured for its drivetrain type
  • 12-month warranty covering manufacturer defects

The Ksport CMZ140-DR Version DR coilover kit delivers the same race-proven hardware trusted on drag strips nationwide, with the fine-tuned setup needed to get the most out of every pass.
