Designed by professional race drivers, the GAB Super HP meets the same high quality standards as the pure racing shocks, but are specifically valved for street use. The twin tube design and specially tuned valving provide superior handling without compromising ride quality. For most applications, the GAB Super HPs are fully adjustable, providing 4-way adjustment for front shocks, and 8 way adjustment for rear shocks. A special feature of the GAB Super HP line is that each adjustment changes both rebound and compression stroke. All GAB Super HP shocks are warranted by the manufacturer for one year from date of purchase.
