STR Strut is a popular and versatile offroad strut/shock combination for rock crawlers, trucks, buggies, desert racers, and other custom off-road builds. The STR struts feature unique dual nitrogen charged chambers for unmatched stability in off-road suspension, and are fully tunable to obtain any level of stability, ride height, and spring rate desired. The STR struts is designed with high grade billet 6061 aluminum, stainless steel internal components, and chrome plated piston shafts to be light weight, durable, and compact. Built into the compression damping is a 1 inch hydraulic bump stop, high flow oil return passageways, and a velocity sensitive compression valve that helps prevent bottoming out on hard hits to make for a 3 stage compression damping stroke. With a compact 3.2" body, 2" piston, and a 1.75" diameter piston shaft, the struts are compact enough to fit under most builds, and strong enough to hold up in harshest conditions. They come in a variety of standard lengths (8"- 20"), and can be custom ordered up to30" travel length.
