BahamaTodd, thanks for the picture! Also, RangerBob, let us know how your install goes with the skidplates.

And SuperMod, I'd be interested in ordering the bolts, but I'll keep an eye on the FS section for when they're ready.

Looks good, just need a washer for that and it will be golden.

If we are going to use the Socket Head Cap Screw, use a washer.

I believe the original bolt was a Flange Head?

If we can get m14x2.0 - 120mm it will give approx. .78 inch drop.

I can get a M14 Socket Head Cap Screw at 120mm but it will require an 1/8 (0.125") washer + 0.500" steel spacer.

coyote - Do you agree that 120mm in length should work?
Let me know so I can order the Socket Head Cap Screws!


I recommend that we use loctite threadlocker!

120mm should work. I want to see if I can drop mine a full inch and see what it looks like.

Ok I have 24 M14-120MM Grade 12.9 Cap head bolts.
They require a 12mm driver.

I should have the 0.500" spacers done by next week!




12mm Driver:

coyote - are you staying with the 0.500" spacers or do you want to go thicker?

I'll use a set of 1" spacers as it'll will almost level the CVs back out. It will leave my diff ~10 & 5/8" off the ground. Just for reference I cranked mine TBs 2".

driveline angle

arent you concerned about the drive line angle?seems to me if you go much farther than 1/2"drop you risk making you front driveline angle too steep which can cause severe vibrations in 4wd
