The HYLO valve gives riders the ability to make independent low speed and high speed compression adjustments to OEM shock absorbers. This valve has four times the adjustable range over the stock TRX450R adjusters! The HYLO valve is designed to keep the pressure balanced inside the shock eliminating hydraulic spike (kicking feel) felt on the square edge bumps. You will be able to adjust bottoming resistance without compromising the plush ride on small chop bumps. The HYLO valves are included on all of our PRO shock packages.

High speed, Low speed adjustable valves are the same type of compression adjusters found on high end aftermarket shocks. Hygear has developed the same type of adjustable compression valve to upgrade your OEM shocks. This gives you the same advantage for a fraction of the price
