    I disagree. If lifted 3" with no diff drop, the angles should be fine. If lifted higher, then the problems are going to materialize. I think alot of the issues with CV's is that people are lifted too much. Realisticly, 4x4's shouldnt go over 2.5" lift in the front....

    Thing is.....The Diff Drop gives more leverage to what ever hits it. It allows more energy to be transfered to the diff when hit, thus causeing damage. Would a different skid have helped? Perhaps. But if that hit was hard enough to do the damage it did......Im not sure any skid would have prevented the damage. I DO belive that, had the diff drop not been installed, the blow received to the front would have created less damage, as the front of the diff would have also been 1" higher, with less ability to have shear forces exerted onto it..

    More info on the tragedy?... Your driving a race truck, I'm guessing you were going somewhere along the line's of 70-90mph? just a guess i dont know how fast you guys go in these races... but ANYTHING hitting a rock at 70mph with 4000lbs of weight pushing it, is gona be in for a hell of a ride!


    I would say this, for some applications maybe they are not the right thing to use. but for the guys that use their truck as a DD and do moderate 4x4 driving, from what I have heard there are no issues related to having a DD kit installed...

    Seeing the third gen section forced me to get a Ford...
    mike is also doing stuff with his truck that 99.999% of people will not do w/ theirs. he's already broken a UCA, COs, spindle?, and other stuff. i'm running the standard DD above my ATO and i do think that if things were changed to incorporate the DD and keep the skid smooth, it wouldnt have happened like that.

    Look at this picture and tell me how much that inner CV is dropped when the front is lowered 1":

    IMG_3058_66b89599808883e93a9060ab309e84359bf59df5.jpg

    You really believe it's helping your angles?

    It was a hairy, blind section of the course. This happened at 20mph.

    I don't think Ray Charles could have seen this coming. Anyone know why?





    Regarding the "debate": For some people, maybe a diff drop makes sense. And I'm not sure MJP's issue would've been avoided if his diff wasn't dropped. Me...I'm gonna make it prove it's necessity before I consider it. Everything I've read leads me to believe 3" or less is fine without a FD drop.

    Larry, IIRC, when you shredded your CVs you were way jacked up on the coilovers, something like 4" in the front wasn't it?

    I know I'm being outspoken minority here (and I have virtually NO experience with this...)

    Looks to me like the DD wasn't at fault - I mean, the spacer looks pristine. So IT didn't fail. The failure looks like the skid plate, and those drop downs didn't help the matter.

    Why do I say that? I'm guessing that the drop-down caught the rock, right? But the skid plate still bent, and that was what actually caused the damage. I don't know what brand skid plates you're running, but I'd talk to them and say something like "Dude, your metal didn't hold and really jacked up my truck. WTF?"

    Are DD's bad in the first place? I don't think that should even be the point of this thread - but again, I defer to those with more knowledge. Better road armor should be the real point, or at least FAILURE of the skid plate. (someone else pointed out that there are skid plates that should fit over the DD)

    The diff drop only drops the axel shafts about 1/8". The only reason I say "1/2" " is I try to give a "Best Case" scenareo.

    Understood, but that is one situation among many. And also, you didn't address Mr. Charles.

    Also, another thought I had:

    Has anyone considered lubricating the OUTSIDE of their CVs regularly with something self-cleaning like DuPont Teflon Lube?

    Seems to me this would slow wear by reducing friction forces between boot fins and also help to keep dirt/grit/etc from getting between the fins and acting as an irritant? My only concern would be a chemical in the lube causing the boot to lose its elasticity or actually corroding the material.

    I think I'm going to try this on mine and be the guinea pig.

    A friend of mine did that on his buggy. The drawback is the lube collects dirt. Even "Dry" lubes impart an electrical charge on the rubber, allowing it to collect dirt, and increase the amount of wear to the rubber.

    Impossible. The differential would have to be mounted near the center of the support arm for that to happen. Again, look at the picture I posted. It's mounted at the rear of the arm, so you're looking at about 1/8" of drop.

    So, wash regularly and re-lube is a possibility there.

    Ok, let's continue to think outside the box. What about coating the CV fins with some kind of easily replaceable armor, like clear nail polish?

    Also....People seem to be missing that the spacer is going to allow forces to be amplified to the cross member when/if hit. Mike was only going around 30 mph ( if that), when he hit the rock...or whatever it was. The impact was a glancing one. about 6" or so ahead od the DD. Had the DD not been installed, the force would not have been exerted to the the cross member in the same mannor. Im making a demonstration with my hands SHOWING you guys exactly what Im talking about....WHY arent you seeing it???? :p

    This is exactly my point. The differential drop itself didn't fail, but it puts critical parts in harm's way while providing 1/8" of benefit.

    The skidplates were modified to clear those spacers. Had the spacers not been there, the bottom would have been smooth and I would have slid right over the obstacle without suffering any damage.

    As for going with other skidplates, All Pro and ATO do not protect the lower control arm mounts.
