Product Details

The Ksport Rally AR Spec Coilover System (CBM090-AR) is engineered specifically for asphalt rally competition, delivering the performance, durability, and adjustability demanded by serious competitors. Built around a monotube design, this system separates oil and gas within the cylinder for superior heat dissipation, finer damping control, and significantly reduced risk of aeration and cavitation compared to conventional twin-tube designs.

Key Features:

  • 36 levels of damping adjustment — simultaneous compression and rebound adjustment for fast, simplified tuning at the track
  • Extended stroke and heavy-duty internals — purpose-built to withstand the rigors of rally competition
  • Pillow ball top mounts (front and rear on select applications) — preserve OEM suspension geometry while delivering a more direct, communicative driving feel
  • Integrated camber adjustability on compatible pillow ball top mounts — adjust camber directly at the coilover without a separate camber kit
  • Adjustable lower mount design — allows ride height changes without sacrificing suspension travel
  • 6061 billet aluminum construction on mounts and major components — lightweight, strong, and corrosion-resistant
  • Zinc electroplated steel shock body — provides long-lasting rust and element resistance
  • Valving matched to installed springs — each set is precisely tuned for optimal ride quality and reliability

The monotube architecture outperforms twin-tube designs in high-demand environments by dissipating heat more effectively, enabling more precise damping adjustments, and maintaining consistent performance during extended competition use.

Ride Height Notes: On many (but not all) applications, the CBM090-AR can maintain OEM ride height levels. Depending on the specific vehicle application, lowering of up to 3 inches from OEM height is achievable. Competitors should verify ride height compliance with their sanctioning body's regulations prior to competition.

Ksport Asphalt Rally Spec AR Coilover Kit - CBM090-AR

Great price and shipping. Just now placed another order because I can rely on them to get my parts to me quick.

More than I wanted to spend on a cargo carrier, and I'm worried it won't fit my vehicle. Hoping for the best!

Received order quickly. I had to return it because I ordered the wrong part. I would not hesitate to order from this company again.

emailed you yesterday and received a response shortly afterword.

Great selection and fast shipping. Not to meantion the lowest prices anywhere on the net.
