  1. Great Price/Great Lift - Posted by: MSalerno87 (6/1/15)

    This lift looks great on my 2004 GMC Sierra 1500 SLT Crew Cab. I had the 2.5" Ready Lift leveling kit installed by the angles of the CV shaft was causing me to tear boots every 3 months. I'm glad I went with the 4 inch RCX lift. I run Toyo Open Country AT2's on 18x9 Pro Comps. The clearance is outstanding. Keep in mind with this lift kit your front tires stick out at least 1.5 inches further than the rear. Overall, would recommend this product!
