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 at a great price and work very well.

Good fit

Disappointed. The picture clearly shows a single 3 inch block. What came was a 2 inch block that I had to stack on the original 1 inch block. Bolts are really long and good quality. You are lucky I kept my original blocks. Otherwise I would be returning it. FIX THE PICTURE OR FIX THE DESCRIPTION!!!

Awsome fit

Item was perfect fit easy installation when you know how to do it and have the right tools 🧰 , Installed in my 2020 Silverado RST Z71.

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.

Fit on my 09 sierra. Had my middle leaf break. So I bought a heavy duty spring pack and added the lifting blocks. Added a lot of clearance for putting more weight in the box.

Not bad they did everything I wanted them to for a good price. You just have to be careful with the ubolts because of the fine thread.

installed the 2” front level/lift a while ago and wasn’t happy anytime I had weight in the back, once these 3” blocks were installed I got my rake back. Seems very solid but for my truck I now need the shock extensions until I replace the shocks with longer ones. With the 3” blocks my shocks on the 2019 Silverado maxed out with a thud on medium potholes

These worked great for me. As my truck had factory blocks of 1.5 inches, I bought these 3 inch ones to add 1.5 inches. Make sure to check your truck before you buy! Truck is now perfectly level. Also make sure to re torque the U bolts a few times after driving as they may shift and settle a bit at first.

Exactly as described. Have a level kit on my 2015 Sierra, but wanted some more rake for towing. Instructions were clear. Install took just over an hour in total using air tools in my driveway including getting organzied and cleanup. I swapped the ubolts first, lifted the leaf spring with a bottle jack and slide the new blocks right into place.
