  1. Great price! - Posted by: Joel (6/29/15)

    My buddy just purchased this kit for his pickup and had me install it for him. Delivery was fast. The only issues I ran into were the following; the most important were the instructions. I've installed quite a few lifts on GM vehicles and the instructions on this were pretty vague. Previous experience helped me, but to the first time installer, it will be frustrating at times. 2, the kit was missing a few bolts/washers/nuts. Wasn't a huge problem for us because the hardware store was close. So double check everything once you open the packages. BUT a few missing bolts/etc is not uncommon with a lift kit. Overall, it was a nice kit. I did not notice a huge difference from this kit versus the other kits I've installed (fabtech, tough country, bds) minus the less expensive price. And after installation, this was the easiest lifted vehicle I've aligned. The caster/camber was on the money and pretty much just had to adjust the toe. Which is a given. If you are mechanically inclined, this kit is definitely awesome for the price!

  2. Fantastic lift, price and quality are the best! - Posted by: Kurtis (5/14/15)

    This kit is one of the best priced kits out there and is made of durable parts. No sense spending another grand on another lift kit just for a name when the parts they make are just as strong. Only thing that wasnt my favorite was grinding down the cooling fins, had to take it out after everything was tightened because it rubbed just a lil bit so we ground the fins down the rest of the way. Overall, would for sure buy another Rough Country lift!!

  3. Great Kit - Posted by: JS (4/8/15)

    I like the kit so far! Two things I don't like are plastic CV spacers and the fact you have to grind down cooling fins on front axle to clear the factory LCA pocket. Mine is still hitting after grinding fins all the way down. I need to cut out and weld a plate in. That's why I didn't give it 5 star.

  4. Definatly a kit to look into getting - Posted by: Matt Starke (3/19/15)

    I just had this kit installed onto my 03 gmc sierra SLE 2500hd .. I would definatly buy another RCX KIT they ride great, look amazing, great price, and also always add a pop to your truck! .. GO AHEAD HIT THE ADD TO CART BUTTON YOU WONT REGRET IT

  5. Great kit that won't break the bank! - Posted by: AJ (6/26/14)

    This kit is awesome! Rides far better than stock. Truck glides over the terrain. Clears 35 inch tires with no problem. If Chevy wheel wells were round like Ford and Dodge you could run larger tires. I love my RCX LIFT KIT!

    Thanks to my dealer Wilson's 4x4. Great job on the installation. I love my truck.
