I installed these shocks on my Isuzu Bighorn/Trooper. I had no trouble installing during lockdown, they just stood. My Bighorn is fitted with a 3.1 4jg2 diesel, I believe the diesel is heavier than the V6 petrol version common in the US. don't know how it affects my experience. I found the driving behavior to be very pleasant, small vibrations are not transmitted to the cabin and large bumps are easily absorbed. I was expecting the ride to be harder, but it's harder to explain than it can be explained in one word. I don't think stiffness is an accurate description, I haven't lost comfort due to stiffness but body tilt has improved a lot. The car has become more comfortable on the open road, it's faster now, I'm very satisfied.
