AUTOPTIM 2 inch Rear Leveling Lift Block Kit, Replacement for 2007-2021 Chevrolet Chevy Silverado 1500, 2007-2019 GMC Sierra 1500 Square Leaf Spring Axle U Bolts Set

Worked as expected

We did fox 2.5 coil overs in the front and 2.5” fox shocks in the rear with a Deaver MiniPak. When we load up the truck with the rooftop tent, two eBikes and the camping gear it squared pretty good. So we put some air bags on it and it just rode horrible reguaress of how little pressure we had in the bags. We even used the Daystar cradles so the airbag would float off the axel during articulation. After looking everything over and speaking with Deaver we decided to go with the 1” block to float off the bag a little. Well…it worked awesome…blocks and U-Bolts are high quality. Our thruck is a 2020 GMC Sierra 1500 4x4…hope this helps!

So let’s get into this in depth in regards to the installation on my 2020 Silverado it’s definitely not for so your average joe it required me to dissemble the upper control arm lower ball joint sway bar and loosen axle and remove strut to install top plate and also swivel the bottom 2 bolts on the strut the complete opposite way to install the rear blocks were much easier loosen up the rear struts unbolt the u bolts and pry the pack up a bit and drop the rear diff and boom back Blocks fit quite well the new u bolts are quite too long but doesn’t affect the functionality over a decent product I will come back and re-review in 6months

Exelente

I struggled a bit but only because I didn't have the correct tools. Spring compressor is a must to rotate the strut. Had to cut the bolts on the cap too but after it was all in it looks perfect

Exactly as described. AAA++9

This wasn’t a bad install, but it was something that I’ve never done before so for the most part everything seated up properly, and I was very happy with the results.

Absolute junk!! This product did not even come with the bolts. I ended up spending more money on the bolts than I did on the product.

Did not fit my 18 Silverado despite saying it will, was the worst purchase I made for that truck, don’t waste your money on this scrap, spend the money and get a quality levelling kit from rough country

Great Happy customer!

This will not fit a 2020 GMC Sierra despite it saying it will on the "fitment" check. I brought it in and once it was on a hoist with everything off it was pretty clear that you would have to heavily modify the installation to make it work. Do not buy this if you have a 2020, thanks for the wasted money 👍

Bought these 1” blocks to drop the back by 1” to level it with my 2” lift in front . Fits and looks perfect . Hardware was good also
