    Unfortunately, you are right. I decided to test the new sleeves on a standard 12mm factory shock bolt and they began to crush and deform just a bit over 65 ft/lbs.

    I think the 2 piece design is a bad idea because the 2 pieces will not say aligned on a 12mm bolt because the fit on the bolt is too loose. As soon as any significant pressure is applied to the sleeves, they misalign which allows them to cut into each other easier and deform. I torqued the pair of sleeves to 65 ft/lbs and the torque wrench did click once but it felt mushy and the sleeves were misaligned and a little deformed. I then increased the torque to 70 ft/lbs and the torque wrench would not click, the sleeves were crushing and deforming more and more as I continued to pull. I stopped pulling the wrench because I did not want the sleeves to become so deformed that I could not get them off the bolt. Then I reduced the torque setting to 65 ft/lbs and tried again. This time the wrench would not click at 65 and the sleeves continued to deform, so I ended the test.

    Even if the sleeves were actually inside the rubber bushings on a shock, they would still misalign and deform because the rubber is not hard enough to prevent the misalignment. In fact I bet the two piece sleeves would still deform somewhere between 65 and 70 ft/lbs even if they did not misalign because the steel is too thin and too soft. I am assuming the new 2 piece sleeves are some grade of stainless steel because it is not magnetic and it is fairly soft because it is easy to mark with a center punch.

    It appears to me that the lower mount and crush sleeves on these Fox shocks has to be increased in size and strength similar to the factory lower shock mounts which are much beefier and stronger as shown in my first set of photos. It also appears that a 2 piece crush sleeve design is not going to work since it seems to reduce the ability of the sleeves to handle torque.

    Here is a pic of the 2 piece sleeves after my test. Since the wrench would not click at 70, the sleeves began to crush significantly somewhere between 65 and 69. I am using a Snap-On industrial brand torque wrench in new condition so I am quite sure the torque is in calibration.

    Donít know if you noticed but the upper sleeve is the same 2 piece design. If you initially torqued them to 80 ft/lbs they have probably deformed as well. They are just as thin on the part inside the bushings. I agree they never feel solid when you go to 65 and when you re-torque they seem to it want to get there. I ended up at 60-62. I had 1 in the rear making some noise made new upper and lower sleeves. Everything seems to be staying tight and no noise now. Did some testing up and over some rocks to get some flex no issues. Iím leaving it alone for now and will keep an eye on things.

    Man this is a bummer. I was about ready to purchased but am turned off by two things:

    1. I had thought the lift was $1,200 but it looks like $1,300
    2. No discount code for forum members is always a bummer - this forum is essentially what has convinced me to buy.
    3. These sleeves crushing. Iíve lost confidence in the product; I do not want to spend $1,300 and then be messing with things because they cannot he torqued correctly.

    Guess Iím back on the sideline waiting to see how this plays out.

    1. A hundred dollar difference between reality and what you had 'thought' the price was going to be doesn't seem like a huge deal for a quality lift kit, in my opinion.
    2. Why should anyone offer a discount? I'm not following....
    3. Here's what I know from past experience with Dynatrac. They care about quality and customer satisfaction. They'll do everything they can to make this right. That's what they do.

    1. Agreed - as a rule of thumb, I am always willing to spend about 10% more than my original "budget" for improved quality. My original budget was $200 for a budget boost. So... selling myself on the $1,200 was already 600% of my original plan. This is not a question of a fair price or value of Dynatrac, it's a question as to whether the value is there *for my use case* compared to a cheaper spacer kit. Also, take it easy on the "reality" vs what I "thought" - I may have made an honest mistake. Did Eddie not say $1,200 in the install video? I may have made a mistake and misheard.

    2. Nobody has to or needs to. I may be mistaken, but I was almost sure Eddie's install video on this kit said $1,200 - then when I saw the $1,300 on the Dyna site, I thought maybe there is a forum discount code that dropped it $100. Of course that's never required, lol - it's a free market. Do you disagree that it's cool when vendors offer forum discounts?

    3. I do have an instant message chat going with them which is cool - my last question was about the crushing and torque specs. I'm hoping to get an idea as to whether they have a fix around the corner that makes sense to wait on, or if I should wait for SEMA as we know the market will likely explode then.

    At the end of the day, my situation is that I'm on the fence as to whether I will appreciate the value of a spring + shock kit over a spacer kit. That plus the price difference between $1,300 and, lets say ~400... plus the new issue with the sleeves crushing are all that is keeping me from ordering now.

    Damn! NO, I did not notice that the upper sleeve is also 2 piece. I did torque both of the upper sleeves in the front shocks to 80 when I first installed them and did not notice that I was crushing the bottom sleeves until I investigated the "mushy" feeling on the second bottom sleeve (could not get 2 solid clicks) and saw the brackets bent way in. It was daylight but I had the Jeep up on jack stands in the garage and somehow there were shadows on the parts and I could not see the brackets bending until I got a flashlight and looked up close. I was shocked and immediately removed both front shocks from the Jeep, luckily there was no damage to the top sleeves.

    Sorry to hear you were getting some noise, I have not had time to test the kit offroad or for flexing, only have maybe 5 miles on flat local streets! I was worried that the low torque on these sleeves (60-65 ft/lbs) would let them move in the brackets during any offroad use - definitely not good!! Interesting that you made new sleeves. Wish I had the tools to do that, lathe etc. Maybe you should go into a side business and sell your sleeves if they test out good. LOL! I'll buy a set since I don't want to have to worry about the shocks coming loose in the brackets.

    Seriously though, I think Fox has to beef up these sleeves, top and bottom, so they can be used on Jeeps without issues. Hope Dynatrac is working with them on a solution.

    1. When we made the video, the lift wasnít even available yet and the price I stated was based on what Dynatrac was hoping to sell it for. I think they got really close.

    2. While there isnít a discount code, Dynatrac did offer one of their kits as a giveaway prize here. You should have entered it as you might have been able to win it for free.

    3. So that it isnít missed, theyíre called ďcrush sleevesĒ for a reason. Them getting crushed a bit will not change the performance of your shocks.

    With all that said, this may not be the right lift kit for you.

    Yep twice the wall thickness plus a little flange would be nice but that would require a new bushing. I think there is too much slope in the holes in the shock mounts which allows the sleeve to misalign and start pushing through the hole. Seems to be staying tight for now. Hopefully Iíd Dynatrac makes some type of upgrade they will offer that to those who already have the kit.

    Thanks. So on number 3, are you saying there is no issue with these crushing before the torque spec?

    EDITED TO ADD: I'm not trying to be a jerk or asking facetiously - generally asking because I don't know the answer to this.

    I had to fix an upper end that was moving a little got crushed a lot trying to go to the wrong torque. I assume my share of responsibility there. everything else is re-torqued to 65 and nice and tight. I donít see there being any problem. My only complaint is the directions, yes the right numbers are there, but as you follow along you come to the wrong specs first. Iím sure this will be corrected. I am happy with the lift and the ride quality. I am in NO way suggesting anyone avoid this product.
