These are definitely an upgrade to the very worn out shocks I had. I purchased this truck used and it was taken care of but not with the best parts. The ride is so good and tight now I'm no longer considering adding a rear anti sway bar kit. I paired these up with some Monroe Reflex Monotubes in the front and the truck rides like new to me (I know I didn't buy it new). Bumpy back roads used to throw the truck all over the road. Now it begs me to go faster as it just hugs any surface. Install was as easy as any other shock. The coil spring didn't get in the way at all. 2000 S10 4x4 "stock" suspension - just well-upgraded.

Was a real task to install, the shocks weren't received or packaged in a compressed state or tied as some are. I wanted the back of the truck raised up more than my air shocks but these didn't raise enough in my opinion. I wanted a no sag rear end even when just the truck bed was loaded these sagged a bit. Most reviewers convinced me to buy them for towing I think my air shocks were better. They are now installed on my truck so I will just have to deal with them now.

    Comments about Monroe Load Adjusting Shock Absorber:

    Although the description says that the ZR2 edition s10 and blazer are excluded.....it still fits great and does great on these vehicles!! The only difference that I would note is that these shock absorbers take away about an inch and a half to two inches of extended length when compared to stock shock absorbers! But overall great product

        Comments about Monroe Load Adjusting Shock Absorber:

        Sensa-trac load adjusting shock absorbers are not currently made to fit properly on a 2001 ZR2 Blazer despite the websites listing it as an exact fit. The 3" factory suspension lift leaves the shock topped out in an unloaded position and cannot operate properly. Should work well on a non-ZR2 model.

            My suspension was in desperate need of a lift. Bought these to stiffen things up. It certainly did this. We will see how they hold up.. But it looks like they will.. Tip on installing on the S-10 because they are 5 inches longer than original shock they need to be compressed. I screwed in top screws. Then I used a small ratchet strap, hooked it above on frame above shock. Then made a loop on strap attached it to bottom of shock above the bolt holes.. Then I could compress easily.

              Comments about Monroe Load Adjusting Shock Absorber:

              Put these on my 2 wheel drive S-10 because I do a lot of towing and haul ATVs and motorcycles in the bed. To ease installation I put a small bottle jack on the top of the leaf spring to flex it away from the frame slightly. This allowed me to slide the lower mount right on (install the upper mounting bolts first). They definiely seem to have stiffened up the rear of the truck nicely. The only reason I did not want to go with the full five stars is because I do not know yet how durable these shocks really are.

Please check the Monroe Sensa-Trac Light Truck Shock Absorber - part# 37066 which is for front and Monroe Sensa-Trac Light Truck Shock Absorber - part# 37069 which is for rear. Both are an exact fit for your vehicle.

                      A new pair of Monroe Sensa-Trac load adjusting shock absorbers can help maintain an even ride height even when up to 1,200 lbs of weight is added - making them ideal for light trucks used for carrying heavy loads or towing trailers.
