KSP 3" Silverado Rear Lift Block, 3in Rear Lift Kits Compatible with Chevy Silverado 1500 1999-2024, 2pc Rear Lift Block with 4pc Extended Square Leaf Spring Ubolts For GMC Sierra 1500 2WD 4WD 99-24

A year or so ago, I ordered the KSP 2.5" front spaces for my 2016 Silverado. The truck looked level at the time but I had Helper Shocks in the rear at the time. The helper shocks were too noisy and squeaked horribly. After removing the shocks, the truck had a squat to it.I ordered these 3" Blocks to replace the factory blocks of ~ 1.25". The result is perfect. I have the lift I desired with the factory rake back.To install these follow the same instructions as someone else posted.With the truck on the ground:-Loosen and remove one ubolt-Install one new longer ubolt with the nuts tightened just enough so the ubolt threads pass completely thru the nut-Repeat for second ubolt on same side-Using a floor jack, lift the leaf spring up away from the axle and support leaf spring with jack stand-Silde existing block out and replace with new block (tapered end toward front of truck)-Remove jack stand and lower spring back on to the new block-Be sure the holes and pins in the new block line up-Torque down new bolts and repart for opposite side.I was able to do this install in 25 minutes in my driveway with a 22mm deep socket and my M18 Impact Gun. Drive the vehicle and retorque the nuts after a 20-30 miles. Instructions were not included but I did 85 ft lbs on my torque wrench.

Worked great

Well made bullet proof extension. Easy install and saved me money. That's a win win for mand you.

I installed these rear shock extenders because my truck’s rear end was riding higher than my hopes during tax season. Every bump felt like I was auditioning for Dancing with the Potholes. Enter these magical little brackets of salvation.Installation was smoother than my uncle’s pickup lines at a gas station. Once in place, my shocks finally stopped crying for help like they were in an action movie. The ride? Silky. Like a velvet hammer. My truck now glides over speed bumps with the poise of a figure skater who lifts weights.Bonus: They made me look like I actually know what I’m doing under the truck. My neighbor asked if I was a mechanic. I told him yes, because technically, I now own a wrench and YouTube.Final verdict? If your lifted truck’s rear shocks are hanging lower than your motivation on a Monday, slap these bad boys on and enjoy a ride smoother than a jazz sax solo.

Worked well repositioned the shocks as needed, I put them on my 5/7 dropped crew cab.. only issue is they mounted to the stock location perfectly but the part that goes to the shock end was too narrow I had to grind it down to get the shock to fit in there. 5 extra mins of modification, but something to note. You could probably bend them to fit if you didn’t have a grinder.

Well made at a great price and work very well.

What I really needed to order was something.I can bolt on for the upper shock arm bolt. To go through the bolthole to go throw bracket a bolt one that's all I need it. Because my Weilds broke on my other one. Did want to have someone else do my job lol blot on upper shock mount yes

Exactly what i was looking for, fit perfectly, it came with everything is needed for the installation and rise the the back of the truck 3" making the look of the truck perfect. I recommend this set.
