These shock extenders are a must have for anyone who has a rear lift of 3” or higher with oem shocks. The oem shocks just don’t have enough travel and would bottom out riding hard. These extend my shocks stroke and travel length allowing a better ride quality! Night and day difference!

These shock extenders are needed after installing the leveling shackles. They don’t take long to install and come with all the nuts, bolts, and washers you need. You will need a good drill bit to drill the brace bolt but it’s quick and simple. Great quality product. Highly recommend.

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.

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.

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.

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

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.
