    Love this lift. Easy to install does take some time if you are doing the install by yourself but very very happy with my purchase. My truck is a 2011 GMC Sierra and this lift gave my truck that aggressive stance. Paired my lift with 285/70/r17 Toyo Open Country R/T tires and 17 inch KMC Spyglass rims. Totally changed the look of my truck. People at my work love the way my truck looks now. get a lot of compliments on it. Rough Country is a company i will be buying more from.

    Love the way it looks. Along with my new Trail grappler G2s in a 285/70/17 it raised my 2008 Silverado 2wd exactly 5.5" in the front and 3.5" in the back. I was shocked. It was easy to do but did take a long time to install and help from a friend would be a big plus. BTW I had the factory 20" wheels before so the tires shouldnt have raised it but about .5-1in

    I love my lift I did it myself and man does it make a difference u can see in the picture I uploaded my dark gray baby ;) i first got the 2inch leveling kit which are the 2 front blocks and I loved it at first but I wanted to go bigger so I looked at the other kits and 3.5 stood out the most but I had questions with the bumb stop I didn't even know where that was located at until I downloaded the instructions it told me to take off everything just to cut that little metal piece which I didn't take off but short story I love the kit I'm proply going to sell it for next year I'm going to go with a 6inch lift and 35s but one bit of advice bring a impact if ur going to do this not for the front but for the back ur going to be there for like 2 hours the u bolts are so freaking long!!!! I think that was proply the hardest part of the instalition but everything else was a breeze I'm in love and would recommend this kit just realignment is a must when ur done or ur going to eat ur tires up thanks rough counrty ;)

    Great product for the price. Took me about 4 1\2 hours to install the hardest part was putting the front spring and shock back in. Considering the local 4x4 place want $900 to install the same lift, and it cost me $150 and 4 hours of my time this is a great product.

    Kit is awesome. Paired with 285/70/17 nitto trail grapplers. Lifted my 2wd Ext Cab a full 5" in the front and 3.5" in the back. Tires accounted for about an inch or so of the difference. I thought I was fairly handy but I have to say it took me about 10-11 hours to install by myself. I would suggest having some help. Ride seems to be the same. Definitely get a front in alignment. Mine was way off but they had no trouble adjusting it.

    If you're gonna install it by yourself it's gonna take a while, but that's the nature of the beast, otherwise it's a great kit that does exactly what it says and at an outstandingly low price.

    After a week of researching different kit I decided to go with Rough Country. It was here two days later and the install was a breeze. It took me 3 hours total and Ai also installed a set of 18x9 XD wheels with Nitto 285/65r18 tires. It raised the front 6 1/2" total and rear 6". The truck looks great and the kit retained the factory ride quality. A small amount of trimming was done to plastic splash guard to clear for tires in a heavy turn. I recommend Rough Country to everyone. -Don Mosley

    Excellent Kit. Installed on my 2012 Silverado 2WD Ext Cab with only hand tools in about 4 hours. I'm pretty experienced with suspension work so someone who is new to it will probably take longer. Raised my 2WD 3.5 to 4. Great aggressive stance. I also purchased the Rough Country 2 inch wheel Spacers and paired them with my factory 18 inch wheels with 275/65/18 toyo AT 2s. Excellent look absolutely love it. I'll be purchasing the hideaway winch mount next( I had one installed previously already) that product also get 5+ stars.

    Rough Country. What the true country boys choose.

    Great, low-cost kit. Install was very easy, especially with the instructions that are included. Took a few hours to install with no problems. Highly recommend getting an alignment, like it says. Silverado 1500 2wd is now 1-2" taller than z71. Raised about 3-3.5" in front, 2-3" in rear. Highly recommend this kit.
