Type HG is designed for rally and / or dirt trail racing. It meets the demands of any road surface with its individual compression / rebound damping force adjustment, and ride height adjustment. Utilizes a twin-tube design, and is constructed with steel for additional durability on rough courses. In order to prevent aeration that can diminish performance, a unique free piston was adapted in the construction of the HG. Developed from TEIN's extensive experience gained in Rally competitions and support.
