These shocks didn't last a full season on my truck, 9 months. All 6 offered little to no resistance and most of them were blown up, leaking liquid. I figured I had other problems with my Peterbilt because it wobbled so much on the road and almost fell me once or twice. I've just pulled half of them out to find they were out of service, the rest are being removed and replaced. I think it's my own fault for buying a cheaper shock absorber.
