  1. Good product for the price. - Posted by: Steven (7/4/15)

    There really isn't a whole lot left on the market for the 5lug 2wd Tahoes/Suburbans. So when I was looking for a 6" lift kits this was one of the few kits I could find even though it was a 4" kit. So upon arrival I was impressed with what you get for what I paid. So here is the good. The quality is there and everything fit together very well and over all I am very happy with the fit and finish of the whole thing.

    Here is the bad. Well not really bad but what could be improved on. The 2" rear blocks are too low considering that the 2wd SUVs sit to low to start with. So some 3" blocks still give you that slightly lower rear without making the truck look like its pulling an invisible trailer. Also due to the rear not being high enough on 2" blocks i blew the rear shocks in less then a year cause there was only about 1" of play before bottoming out. Once again a problem a good set of 3" rear blocks would fix.

    The only other thing I would add to this kit is some rear wheel spacers. The knuckles widen the front track width a bunch. And on a truck where the front is already wider then the rear when you put all this together and a looks a little much difference from to back. I'd say with a 1" wheel spacer in the rear would still keep the rear narrower then the front but not so extreme looking.

    And the last thing which is not rough country's fault. Is I would consider looking at 33"s over 31"s. I prefer the more baja look which this kit offers. Regardless of the look your going for the 33" tires would probably fit it a little better. 31" tires almost look small on it.

    So all and all Rough Country thank you for building a quality kit for an affordable price.
    I do not know if my suggestion about the 3" blocks would work for the 1500 pickups considering they do not hold as much weight over the rear end. But for Tahoes & Suburbans I slipped in a 3" block and it made all the difference in the world.
