I've read sooo many bad reviews on here from people that obviously shouldn't be doing custom work for themselves! If you're not smart enough to know that if a bolt is going to rub an axel shaft if you install it from the bottom that maybe you should install it from the top down you have NO BUSINESS UNDER YOUR TRUCK. Now that being said.Great blocks, didn't have the logo as pictured but who is looking for that under my truck? Supplied bolts are grade 5 not grade 8 (Count lines on head and add two if you don't know how to tell) Factory bolts are grade 5 there is no reason to put grade 8 in. Do yourself a favor, just take it all apart. If you try to "cheat" it into place you're going to end up with something in a bind. Now is a GREAT time to change ball joints, upper control arms, stabilizer bushings, etc. As you install this make sure to loosen (not remove) the upper strut bolts also so all of that can move and realign properly. This may put your upper ball joint at it's limit, you may want to consider and upper control arm & ball joint with a lifted offset. This will solve your cast and camber problems if a leveling kit creates one. You are changing the geomtry of the front of your truck, this can cause you to have to buy other parts to make it all line up and drive right. Welcome to the rabbit hole of custom trucks, your wife will not be happy you're here LOL. MOOG makes a great replacement upper control arm with offset, that gives you a couple degrees of cast and camber. I wish I would have went ahead and changed out my struts while I was there. But honestly if you're going to do that rancho's loaded strut quick lift is the right answer instead of this block (they are $300). These blocks work great, but if you're even close to needing struts look at the rancho loaded quick lift, you dont even need a spring compressor, they are pre loaded. Hope this helps someone make a decission, please don't take the above information wrong, these blocks will most definatly level your truck for $40 and it is a GREAT, WEELL MADE PRODUCT. Just don't be supprised if there is something else (Upper control arm with offset ball joint) you'll have to buy to make this work. And if you are going to have to replace struts soon anyway the Rancho quick lift loaded struts are about $60 more (both sides) than the Monroe quick (loaded) struts. So for $20 more than this kit you level it with the struts.And finally, I dont care what these guys say, YOU HAVE TO ALIGN YOUR TRUCK AFTER INSTALL THE FRONT WILL BE TOWED. But don't take my word for it, destroy a brand new set off 33's instead.

IM PLEASED... EXTREMELY PLEASED..I love my 2015 GMC Sierra Crew Cab too much to mess something up and didnt wanna spend the money for professionals to do it but I figured what the heck, 100% bolt on no special tools required but 15mm wrench, a crescent wrench, and 2 sockets (18mm and 15mm). Let's proceed.First off the kit comes with 2 billet aluminum spacers, 4 bolts, 8 washers, 4 nuts, and instructions.INSTALL TIP: for ease of installment. I followed the youtube video "2010 Rough Country Leveling Kit Install" TO THE TEE! However when trying to pry the strut up there was an extreme amount of pressure and it just felt as though someone was gonna get hurt. Didnt feel normal. Well after about an hour of trying to watch every moving part while prying and also trying to observe what is happening as well as "what needs to happen" ..FINALLY WE SPOTTED THE PROBLEM... we noticed one important step missing in the video instructions that would make the install go from 1.5 hours to 20 minutes tops GAURANTEED, WHICH IS JUST OUR OPINION. But if somehow you were able to get it by watching the video in this post and following those steps then most likely your here reading this because you broke something or messed something up and want to know of that easier way you could have done it.In the video they stated loosening and leaving the sway bar bolt loose. For us this was humanly impossible to pry the strut far enough away from the lower control arm to slip the spacer in safely. We simply unscrewed the top nut and removed it completely from the sway bar but left the bolt in place. Giving you MUCH more room to move strut up and down. Next we easily picked the strut up away from the control arm and placed the spacer in place and wiggled the pry bar back and forth to align holes to accept bolts. We used a small vertical hydraulic jack to crank the lower control arm up to allow bolt for sway bar to protrude through enough for nut to catch.Your also going to need the 7/32 allen to keep the ball joint from spinning when tightening your control arm nut. Also FYI the other side took us 12 minutes TIMED!!! Trust me just just remove the to nut completely from the sway bar. Now that we are finished and see the bigger picture of what we needed to do I consider this install a very very simple install probably a 2 or 3 on a 10 scale of difficulty.I don't ever post on anything but figured my two cents may save someone an hour of daylight. PLEASE GIVE THUMBS UP IF THIS REVIEW HELPED IN ANY WAY! Thanks God bless.Update 4/9/2017: Since I first wrote this article, I have since installed this kit on a number of trucks and SUVs. All were equally easy and came out nice! MOTOFAB is the way to go! Dont settle for anything less!! Other brands have packaging issues, broken parts, missing pieces, uneven bolts, long bolts, misthreaded bolts, unthreaded bolts, etc... MotoFab has an unmatched Quality Control department that ensures correct blemish free products."
