Fully Adjustable Coilover Kits provide the ultimate in suspension technology for your street or track car. 16 levels of dampening adjustment allow you to fine tune the ride to your handling and comfort needs. The dampening adjusts compression and rebound simultaneously for ease of adjustment. Pillow ball top mounts in the front and rear on some applications allow you to maintain vehicle manufacturer suspension geometry design. The pillow ball top mounts also allow you a more direct feel for solid driver response. Most applications utilize an adjustable lower mount, which means you adjust height without losing suspension travel like some other coilover designs do. With the mounts and most pieces of the coilover being designed for 6061 billet aluminum the kit is lightweight, durable, and rust resistant. The steel shock body is eIectroplated with zinc to resist rust and the elements. The valving of each set is matched to the springs installed for unmatched ride quality and reliability.
The ARK system uses a Monotube design in which the oil and gas are separated within the cylinder. When compared to twin tube designs the Monotube dissipates heat better, allows finer dampening adjustments, and requires more expensive design process. Aeration and cavatation are a lot less common in a Monotube design, which results in a better ride. The ARK DT-P Coilover system has been designed with professional road racing in mind offering extremely high value and performance.
