  1. Very please - Posted by: 2013 Silverado (6/12/15)

    Everything went smooth, 4 1/2 hours to install. Bolts did spin in the strut spacers, not a hard fix. Went with 10 ply Terra Grapplers 2, they give it a Rough ride. Lift is great!

  2. Great Kit. - Posted by: 08' GMC Sierra 1500 Extended Cab (5/15/15)

    The installation was not too bad. It took me about 12 hours total doing it solo That includes a trip to auto parts store for an extractor to remove some lower strut bolts that the heads broke off, and a trip to a craft shop to weld the stud extensions on the strut spacers because a few were spinning. I was very pleased with the customer service. I pull a trailer often and hate the look of a squatting truck, they worked with me and sent me bigger blocks for the rear. Now the truck is 1" high in the rear with no load, and dead level with the trailer. Highly recommend this lift, easy install.

  3. Very nice kit - Posted by: Travis (5/5/15)

    Overall I would say that this is a very solid kit that def makes your chevy look good as the half tons stock form don't really have much clearance. This kit takes care of that. Put kit on a 2007 1500 extended cab with 285 70 17 bfgoodrich ko2 all terrain on stock wheels. No rub. Very smooth ride. Looks great. Took me bout 10 hrs solo. Little advice when mounting passenger side diff drop mount. It says to take off stock diff bracket an knockout the two studs the will hold the new drop mount. This looked to be a real pain so I just took the hammer an knocked them out while still on the truck. Worked fine. Def would recommend getting at least 33's to put on. Great kit!!!

  4. great kit for the price - Posted by: nick (5/4/15)

    Took a little longer than expected. But overall I'm very satisfied with the kit. The area I hunt has some pretty deep holes and ruts made it threw without bottoming out. Still have stock wheels and tires on it 265/70/17. On a 07 1500 would most definitely recommend this product to anyone. It's very affordable and keeps the ride quality on and off the road!!!

  5. Great kit !! Love it - Posted by: ECaste90 (4/20/15)

    I just installed this kit over the weekend on my 2011 1500 Silverado Z71 Took me about 4 hrs. to install went real good I do agree with the last review The only thing I didn't like was grinding my front differential but all went good fits perfect also had to weld the upper studs in the plates they spun in the holes minor fix Love the look of the truck now I used my factory wheels no spacers needed 285/65/18 BFG All Terrain tires were used Highly recommend this Kit !!

  6. Good solid kit for the price - Posted by: chevy 1500 (4/4/15)

    If u are like me and are using ur truck as ur daily driver rough country makes kits that give u an awesome look but still don't take away from ur ride quality without having to dish out 2,000-5000 grand which is nice I have heard they are good off-road too but I don't take my truck offroad so I wouldn't know but overall great solid kit

  7. Very pleased - Posted by: Blake (3/22/15)

    I am pleased with this lift, for the price you cant go wrong. I installed it on my 08 chevy 1500 vortex max, only thing i didnt like was that i had to drop the front diff and grind on it( its in the instructions to do so) outher than that very simple to install, i am running a 34"x12" tire with a -12 offset rim and had to trim the finder well a little. I would recamend it.
