      No Revalves Necessary

      The ultra wide range of adjustment offered by the CFD piston allows for the convenience of tuning your suspension without having to revalve your dampers. A conventional shock absorber can withstand a 2kg spring rate difference before requiring a revalve, whereas the Concave Flow Digressive Technology has a broad range of 8kg spring rates. This is invaluable for tuning your suspension quickly at the track on race day.

      Jekyll and Hyde

      The Concave Flow Digressive Piston allows for a Jekyll and Hyde personality. Lower spring rates can be stiffened up by using the wide damping range as an artificial spring rate, while higher spring rates feel much smoother. The large adjustment range contributes to a comfortable ride on the street and unyielding performance on the track, all with the twist of a single adjustment knob.

      Custom spring rates are available. You can request custom spring rates by entering the rates you want in the special instructions box after clicking add to cart. Spring rates up to 18K are available on standard Springs. Rates higher then 18K will require Swift springs or Hyperco springs upgrade.

      510 Series Coilovers are custom hand-built to order with a lead time of 3-4 weeks before shipping.

      • Front Spring Rate: 4K to 16K
