    Comments about Pro Comp Suspension 6 Inch Crossmember/Knuckle Lift Kit with ES9000 Shocks:

    it says it will allow for a 5.5 inch backspace wheel and i ordered XD misfit wheels which have a 5 inch backspace so i thought id be clear. well the manual it comes with says 4.5 is max. so in order to clear the tie rods i now have to use .5" spacers. im not happy about this.

      I did a lot of research and compared a number of shops before deciding on the ProComp 6 inch lift for my 2010 Silverado from 4 Wheel Parts. The store manager Eric, took the time to show me the similarities and differences between different 6 inch lifts. I am a 4 Wheel Parts customer for life. Thanks for taking great care of us military customers Eric!

          The Pro Comp system is great. It makes my truck look totally like a new truck and my truck is only an 08. I was apprehensive at first due to this being a six inch lift but now I would recommend it to anyone looking to lift their truck.

          Service and delivery comments:

          The guys did another great job and they even beat the time on their install. Thanks.

              I had a very good experience with this product. Installation went good, if you have one good helper you can meet the 10 hour installation they say if takes. I like a level ride that is the only thing about this product. It needs to be about 1/2 to 1" taller in the rear. To me it rides better than stock, especially on dirt roads.

              • Q:

                I installed this lift on my 2013 Silverado 1500 & absolutely love it. The only thing I'm not thrilled about is the fact the truck is not level, its now slightly lower in the rear. What can I do to raise the rear end of the truck an inch or so? I've used procomp lifts on all my trucks in the past & they are usually level. Thanks-

                  Jerry,

                  The 35" tall tires on the Pro Comp Suspension 6 Inch Crossmember/Knuckle Lift Kit with ES9000 Shocks will work fine on your truck with minimal strain on your transmission. What we usually recommend doing is driving around for a couple hundred miles to see if you like the new driving characteristics of your truck before deciding to change the gears.

                  Jon-

                  Thanks for the question. The note for the Pro Comp Suspension 6 Inch Crossmember/Knuckle Lift Kit with ES9000 Shocks is as follows. For this application, we recommend a 17” or larger wheel not to exceed 8” in width with a maximum backspacing of 5” must be used. additionally, a quality tire of radial design, not exceeding 35” tall X 12.5” wide is also recommended. Please note that the use of a 35”X 12.5” tire may require modification to the front valance. If the truck is new, no reason to change the u joints unless they have play allready.

                  Thank you for your question. The Pro Comp Suspension 6 Inch Crossmember/Knuckle Lift Kit with ES9000 Shocks does not require you to get new or lengthen your drive shafts. Remember that you are drastically changing the angle of the drive line and you should replace your U joints at the time of the lift install.
