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

    Lift install went on without any major issues which is unusual for a project like this. Instructions and diagrams were very helpful. Truck rides great and looks awesome. Able to ride on 35s with just some minor trimming of the front bumper and the wheel well trim.

    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!

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

          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.
