  1. Satisfied overall. - Posted by: CJ (3/20/15)

    Looks great, rides great, was fairly straight forward to install.
    Only thing I would disclose is that with the stock wheels, turning to full lock will make them rub on the new upper control arms. Spacers eliminated that though. Overall I'm very happy with it.

  2. Installed the kit myself. - Posted by: Dan (3/12/15)

    I installed this lift kit on my 2000 chevy blazer 4wd and the install instructions made the installation very simple and straight forward. The truck looks great but I think my expectations were too high because I was slightly disappointed by the tire - fender gap. For some reason I expected more gap but the increase in ride height is correct.

    Quality gets 4 stars because even with the differential drop brackets, my cv axles still bind when hitting big bumps on the highway with the ride height level front to back. I would strongly suggest dropping the differential at least another half inch. Maybe even a whole inch. I feel that this would dramatically improve longevity of the cv axles and drivability after the installation is complete.

    I personally feel that the instructions should be modified to not remove the passenger cv axle during installation. When I removed my passenger cv axle, the axle pulled out the intermediate shaft inside the differential and the axle tube needed to be pulled apart and everything reassembled. It created a lot more work and a headache that I would have rather not had to deal with.

    Instead of removing the axle from the differential, it would almost be easier to use a jack to support the differential, still in the vehicle, while doing your cutting for the drop bracket. This I feel would eliminate the risk of differential damage if the cv axle becomes stuck.

    Aside from the instructions telling you to remove the passenger cv axle, which I feel is unnecessary, and the drop bracket not dropping the differential low enough to really make a difference in cv angles, I really like the kit and would definitely recommend it to a friend.

  3. Did it myself - Posted by: The Outforce (2/16/15)

    Great and easy todo with help from a mechanically inclinded friend or two. The rear shackles are a bit tricky because the bolts will be seazed in, an oxy acet torch is really helpfull just use a bearing race driver to install new bushing there ~$10 a piece it wont hurt the wallet to much, i had to melt mine out, but other than that everything went rather smoothly, DONT RUSH!

    Pro Tip- make sure to tighten/torque down everything then get an alignment and a inspection done to make sure everythings good to go, FOLLOW THE INSTRUCTIONS CAREFULLY!
