Product Details

The Ksport CMZ140-AR Rally AR Spec Coilover System is purpose-built for asphalt rally competition, delivering the extended stroke, heavy-duty internals, and precise damping control that serious competitors demand. With 36 levels of damping adjustment, drivers can fine-tune compression and rebound simultaneously to match changing road conditions, tire compounds, and driving styles — all with a single adjustment.

Key Features:

  • 36-Way Simultaneous Damping Adjustment — Compression and rebound adjust together for fast, consistent setup changes at the stage
  • Monotube High-Pressure Design — Oil and gas are separated within the cylinder for superior heat dissipation, finer damping control, and reduced risk of aeration and cavitation compared to twin-tube designs
  • Extended Stroke Construction — Heavy-duty internals engineered to handle the demands of competitive rally driving on paved surfaces
  • Large-Diameter Pistons — Increased oil capacity for improved cooling efficiency and more consistent damping performance under sustained competition use
  • Application-Matched Valving — Spring rates and shock damping settings are carefully selected and matched per application for optimal handling balance and reliability
  • 6061 Billet Aluminum Construction — Mounts and major components are CNC-machined from 6061 billet aluminum for a lightweight, durable, and corrosion-resistant build
  • Zinc-Electroplated Steel Shock Body — Provides long-term rust resistance and protection from the elements
  • Pillowball Top Mounts (Select Applications) — Front and rear pillowball mounts preserve OEM suspension geometry while delivering a more direct, responsive feel for improved driver feedback; many applications include built-in camber adjustability, eliminating the need for a separate camber kit
  • Adjustable Lower Mount — Ride height is adjusted without sacrificing suspension travel, maintaining full shock stroke across the height range
  • Height Range — On applicable vehicles, the system can achieve OEM ride height or lower up to 3 inches below stock level

Note: The Ksport Rally AR Spec system is built to order. Height range varies by application — on many (but not all) vehicles, OEM height is achievable. Rally competitors should verify ride height compliance with their sanctioning body's regulations before competing. This product is not compatible with OEM electronic damping control systems (EDC, DDS, etc.).

Autoplicity simply had the best prices available and everything was in stock to be shipped.

Billing/shipping db is a little quirky.

Autoplicity leads the way ! Others take a lesson !! Great prices and excellent service !!!

No problems ordering a leak down tester from Autoplicity which had the lowest price and reasonable shipping charges. The item was well packaged and I would buy from them again.
