  1. Perfect kit for a stock z71 - Posted by: Mitch (6/29/15)

    This kit is the best kit for a good looking z71, the tires stick out a lil on the front, which I kinda like.Great kit rough country :D

  2. Great buy - Posted by: James (4/28/15)

    I put this lift on my 02 silverado,all around a great buy can't complain at took my buddy 2hrs to complete,i didn't put the blocks in the back just cause I wanted the cali lean it was pretty self explanatory on how to install.the only problem we had is the rims would fit cause the guy gave us the wrong ones an we needed a -10 offset I took care of it mon afternoon an every thing is good now.i would definitely recommend this lift to any one trying to lift there truck an not spend to much...I put 17in on extreme all terrain pro comps 305/65/17 we had to trim some thing but everything turned out great.....

  3. Great product, Lower price - Posted by: Derstin (4/8/15)

    I have a 1999 silverado extended cab ls 2wd and I wanted to have my truck sit a litte higher than the stock 2wd suspension. This was a great way to do it. The lift kit is good quality, spindle and block are well made.... But the nitro 2.0 shocks... AMAZING!
    Truck ride high, smoother, and handles bumps better. I can now for some 31 inch tires on it!! Great product and it's cheaper than other companies are selling the same kind of kit for id recommend it!

  4. Great Look - Posted by: Will (3/25/15)

    Took about 5 hours to install on an 07 classic. Gave a full 3" in front and 2" in the back. Installing the lift blocks was very simple and took maybe an hour or so. The knuckles were simple but took longer than i thought. The only problems i ran into were the new holes to mount the brake caliper on were blocked by the dust shield so we had to trim a bit off the dust shield and RC doesn't tell you how to run the brake lines so you just have to eyeball them and make sure they dont rub anywhere. All in all a very easy kit to install and pretty well engineered. Gave my truck an aggressive stance. One thing i dont like is that the new knuckles make the front wheels stick out about a half inch more than the back which looks a little funny but with bigger tires or fender flares you wouldn't notice it.

  5. awesome - Posted by: jake (2/8/15)

    Great buy. The only thing we had some issues with a few bolts that had rusted together and we didnt have the right tools to get the ball joint separated (Lucky our neighbor had the right tool). And we had issues with the brakeline braket thing it rusted closed. It took us a long ass time to complete the lift(8 1/2 hrs) but with the right tools it will go fast and easy. All and all great buy even better price very happy with the end results. Oh and in the instructions one part said you need a 18mm socket when you actually need a 22mm

  6. Nice kit! - Posted by: 81k5guy (2/6/15)

    Installed this on my 05 Silverado. Sits even with my dads 05 z71

  7. Very satisfied. - Posted by: Steven (2/1/15)

    This kit is a lot of work. It wore me out. But my truck looks like a real truck now.

    Blocks and shocks are good quality components. But the steering knuckles, WOW! There's some real weight there! This is a well engineered kit.

  8. well worth it - Posted by: jacob (1/7/15)

    bought and installed on an 07 classic. was well worth it, easy install and it gave the truck a much better stance and looked great. All around a great value.
