Product Details

The Ksport Rally AR Spec Coilover System (CBM031-AR) is engineered specifically for asphalt rally competition, combining extended stroke capability, heavy-duty internal components, and precise damping control into a complete suspension solution.

Damping & Adjustability:

  • 36 levels of damping adjustment for precise fine-tuning of ride and handling characteristics
  • Simultaneous compression and rebound adjustment for quick, simplified setup changes
  • Adjustable lower mount design allows ride height changes without sacrificing suspension travel
  • Lowering range of up to 3 inches from OEM ride height on supported applications

Monotube Design:

  • True monotube shock construction separates oil and gas within a single cylinder
  • Superior heat dissipation compared to twin-tube designs
  • Finer damping resolution and reduced risk of aeration and cavitation
  • Valving is matched specifically to the installed springs for optimized ride quality and reliability

Construction & Materials:

  • Mounts and key structural components machined from 6061 billet aluminum — lightweight, durable, and corrosion-resistant
  • Steel shock body features zinc electroplating for rust and element resistance
  • Pillow ball top mounts (front and rear on select applications) preserve OEM suspension geometry while delivering direct, responsive driver feedback
  • Camber adjustability integrated into pillow ball top mounts on applicable fitments — no separate camber kit required

Rally Competition Notes:

  • Designed to meet the demands of sanctioned asphalt rally events
  • On many applications, the system can maintain OEM ride height — important for compliance with sanctioning body ride height regulations
  • Extended stroke internals support the rigors of competitive rally driving

The Ksport CBM031-AR Rally AR Spec system delivers a purpose-built, competition-grade coilover solution with the adjustability, durability, and precision engineering demanded by serious asphalt rally competitors.
