Solved my vibes - by Benzoil04 , 2022-03-23 02:39:14

I recently had a 3-inch Rough Country lift installed on my 2004 Chevy Silverado 2500HD 8.1 l Vortec. The lift did not come with a diff drop. As a result, my CV angles were pretty extreme and I was experiencing pretty bad vibrations at highway speeds. This diff drop cured both issues and I am very happy with it now. To those of you who are considering a 3in lift for your Silverado, I would recommend the 3in zone Adventure series kit. The diff drop is crucial.

Great price , great fit , great product. Written directions leave a lot to be desired. There is a Youtube video that makes it very easy to understand. I'm 62 years old , have had several 4x4s but this took me by myself with replacing cross member bushings which if you have an older truck you to should do , new keys and kit apx.8 hours. Now that I've done it I think I could do it all in 5 hours or with help 4 hours. Great product , fit perfectly. What I will say is to me the best way to get front end back in is to hang it off top bracket using a jack then after you've done your cutting and drilling of new lower bracket put lower bracket on. If you try to put on lower bracket you'll probably not be able to get front end in.

Great product everything fit , all bolts were there . I will say the written directions leave a lot to be desired but on YouTube there’s a couple of guys that made a video that was very helpful. Quality of kit is perfect and fits perfect along with a great price.

  • Does this kit fit on a 2002 escalde

    This item is for the 2001-2010 GM 2500HD/3500HD model vehicles. It will relocat the differential to maintain proper CV Shaft angles.

  • Will this work with a rough country 3in lift.

    This item is designed to drop the differential on the 2001-2010 GM 2500/3500 HD model trucks with a 2.5" to 3" Leveling Lift installed. It will not work with any other differential drops previously installed with a leveling/lift.

  • Are any modifications required, or is it a direct bolt on?

    Yes this unit does require modifications to the Differential Mount brackets. A bracket needs to be cut and another bracket welded into place.
