  1. It is what it says it is 4 Star Review

    Posted by on 12th Mar 2021

    4 Bolts, 4 Washers, 4 Spacers. Not much to it. Only thing I did not like was receiving a shipping notification with tracking 3 days before it actually shipped. The parts shipped USPS Priority which is 2 day delivery, but took 6 days to arrive due to not being actually shipped for a couple days after I ordered. Ordered on Tuesday, received the following Monday.

  2. Well worth the money and very easy install! 5 Star Review

    Posted by on 13th Aug 2020

    2018 Chevrolet 3500. I have the FabTech 3-1/2" leveling kit with steering Knuckles and UCA's turned down to about 2". I wanted these to get the angles back closer to stock. Worked like a champ and very easy to install. I loosened all 4 bolts down to where the nuts were still holding the stock bolts and then did one bolt and spacer at a time. Took about 45 minutes or so. I did end up putting bigger washers on the new bolt heads. The ones sent were very small compared to stock. No big deal though. I would recommend them for sure.

  3. Don’t Hesitate!! Excellent Value and Makes a World of Difference!! 5 Star Review

    Best $40 I’ve ever spent. Well, besides that one time in Mexico. This was super easy to install. No cutting, no grinding and smoothed out the ride by correcting the CV angles. This made a real difference and is a must have. It is amazing how much better my truck rides and feels. Thanks CCM!

  4. Good Product & Easy Install 4 Star Review

    Posted by on 27th Aug 2019

    Kit components are good quality. Installation took about an hour with the proper tools. Only wish the included washers were a larger diameter similar to the stock hardware.

  5. Great product, easy install 5 Star Review

    Posted by on 12th Jun 2019

    I purchased this kit to help get my CVs as flat as possible on my 2013 LML. I am pleased to say that the kit was super easy to install and great quality. Took less than an hour with the proper tools. My CVs are at a much better operating angle now, nearly flat with my current configuration. I can't tell if its in my head or not, but I do believe the truck drives better now. Likely due to better angles which minimized vibrations. Thanks CCM!

  6. Robust and Just right 5 Star Review

    Posted by on 24th Apr 2018

    I just put this kit on last night and this morning I noticed more harmony in the front end as I drove to work. My cv angles are better and the diff dropped 5/8’’. This kit is robust and solid. There isn’t any other way to say it. I am very happy with the results. If you are on the fence about this...don’t be. Do this mod.

    This was easy to install just a couple jack stands and a floor jack to hold the diff in place , quality is good and it does help on cv angles .

  8. Easy install - great product for such small issue 5 Star Review

    Posted by on 6th Jun 2017

    Easy install - great product for such small issue.
    Had to completely remove all bolts from the Diff carrier to install the larger spacer but worked great none the less, still looking for the vibration issue but I can say that it is not from the Diff carrier being too high now... thank you for such a good product.

  10. 17 3500hd 5 Star Review

    Posted by on 31st Mar 2017

    I ended up milling down the spacers from 1" to 3/4 of a inch. I never tried to fit them at 1" just eyeballed it and look to be a little bit of a fit mit issue on the pass side rear cross member. Also I only had my stock keys turned up to where I still had a 1 1/4" low in the front rake. After installing the 3/4" spacers the cv angles are perfect just like stock. Fairly easy install with a 3/8s drive ratchet with a flex head.
