  1. Excellent lift kit - Posted by: Michael (8/18/14)

    This lift kit worked perfect for my '85 M1010 CUCV (k30) . All parts are heavy duty and you can't beat the price.

    Two bad points about the kit is no shock boots are included so be sure to order them with the kit (that's lame) , and the instructions are kind of vague and seem to be written for general install of a lift kit, not vehicle specific, which makes you guess a little. But a call to Rough Country customer service for a little guidance was all I needed to help me complete my install. The rep was very kind and helpful.

    I do recommend installing this lift kit in a shop that has a full lift to use, I used jacks and jack stands and this made the install a lot more time consuming and more work.

    All in all if you are looking for a good suspension and more height on your Chevy then this kit is the way to go.
