These shock absorbers were installed on a 1996 Toyota Tacoma 4x4. 15 months after installation, both shock absorbers burst. A little on top because fluid was leaking on top and the dampers had no resistance either inwards or outwards. I could never tell the difference with the adjustable handle. I don't drive this truck off-road. This is my daily driver and I took some wood and stuff with me. These upheavals were a great disappointment. Back to Bilstiens, who lasted over 10 years before trying these shocks. Revain does very little to help with the warranty on this item. you're pretty much alone
