KSP 3" Silverado Rear Lift Block For GMC Sierra 1500 2WD 4WD 07-24 | 3in Rear Lift Kits Fit for Chevy Silverado 1500 2007-2024, 2pc Rear Lift Block with 4pc Extended Square Leaf Spring Ubolts

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.

All the specs for this kit matched up perfectly for our 2006 NISSAN TITAN 4x4. Very high quality materials and actually showed up at my door earlier than expected. Just wanted to say thanks so very much for listing all the important details about the kit on Amazon. I was able to order it without the worry that it might not fit correct. Thanks again and please guys don’t hesitate to buy this super strong kit. Also I’m a welder and I was very impressed with the welds.

Well made at a great price and work very well.

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.

U bolts not for larger trucks... Too small... All works as designed however. Though I can't attest to u bolts... They sit on shelf waiting for a smaller project to come along. As stated by another helpful review.

Awsome fit

Good fit

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.

Great kit installed into my 85 chevy truck bolts are strong simple install

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.
