These shocks come all the way up from down under, where Australian engineers have custom-built a tough off-road shock absorber for Range Rovers, Discovery I & Series II, and Defender 90/110. The giant 18mm shaft is made of induction hardened steel then chromed to a superfine finish. A check valve insures consistent gas pressure even under the toughest off-road conditions. A Teflon-coated guide bush significantly reduces heat build up, and a stone guard protects the oil seal and piston rod against flying stones and dirt built-up. Thoroughly tested and imporved in Australia's rugged outback, these shocks are ready for your own test and approval.
