  1. 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

  2. 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.
