Found a HD front cover that should work for all lifts and track bars that fit the stock cover!!! It's made from 3/8" A356 T6 aerospace grade hardened cast aluminum. Has a full 1" thick lower mounting flange and 1/2" thick upper. It's made by ODC, and they made the mold from the actual factory OEM covers. This came about they said after they seen so many complaints of clearence issues with their own "extreme offroad" series cover, as well as most other aftermarket diff covers.

Called and talked directly to the lead design engineer, after I had to cancel my order for a front extreme cover due to the concerns raised in this thread. He like all the others stated they tested on over a dozen different rigs and cleared the tiered and trackbar when flexed out with no problems. He directed me to their newest product he said came directly from requests from desert racers who constantly see the type of suspension compression that leads to these problems but still need a strong cover that also dissipates heat the way aluminum does.

That's a great example of how companies and their "lead design engineers" don't understand the mechanics of this problem.

as I showed in a post #862, it really says nothing if it clears when flexed out. You need to pull the springs and push the axle to full bump.

Flexed:


Full bump:


BIG DIFFERENCE.

Hey, you gotta give them credit for recognizing the the testing procedures of their original "Extreme" series covers was flawed and in real life street/offroad testing by the public had clearence problems and decided to listen to their customers demands by designing and bringing to market, a Lo-pro style cover based on the factory OEM profile. This is a real viable alternative for those needing, or wanting a stronger than stock cover, and really is a unique, yet very simple solution I wish others would follow!...........Oh, and they are made right here in the U.S.A.!!!!!!!

Seriously, how hard would it be for other companies that make steel covers to make a 1/4"-3/8" hard plate stamped steel cover identical to the standard OEM profile?

Here's a few pics (albeit small) of the above mentioned diff covers.

So this moved the trackbar forward and farther to the drivers side? Do you have better pics of the mount and the bracket?

you don't even have to show me full bump pics and i can see its an issue. i'd guess it needs at least 2" front bumpstop just by looking at it. check out my pic, and see where the flex joint sits realitive to the straight part of the tie-rod...yours is moved forward and down even more...the bolt is going to hit the tierod.

i'll definitely check it out and get some new pics as soon as im able. should i flip the bolt around or do you think it would still hit? i need bumpstops anyway just so my tires don't hit the fenders.

Jeffrey sent me the same "new" one with different bends but it ended up being exactly the same as the one i already have on there just slighty longer at the axle end. But the bends were the same. the only difference would have been my joint on the axle end would have been threaded in further so i didnt even bother installing it.

here it is for refrence...

you've got to compress that jounce bumper fully till the cup touches the spring pad. theres still a good 2"+ compression there till you reach full bump. yet another track bar that doesn't work.

Ok, but there is another reason for bump stops that nobody seems to be pointing out here!!!! I don't know why people are dead set on removing the springs to check clearence and set bumpstops. That can be a recipe for disaster in and of itself.

You need to see what the total compressed height is with springs installed! If someone places bumpstops that are one inch shorter than what the stacked/compressed height of said spring is, and comes down hard on the suspension, you can literally break your coil pack!!!

For instance........if the measured height between upper and lower spring pads with springs and bumps removed is 8" and your coils only compress to 9", you need at least 1" bumpstops to prevent blowing out your coils. I know with my current RC 2.5" progressives, I can strap it down to the trailer till the coils are completely stacked/compressed and with factory stops, the upper snubber just barely touches the bottoms pad. I really need 1" stops now, and not even worried with diff clearence!!!
