Got the diff cover from Barnes 4wd. Have to brag on Brad. This is a nice product! I lost about 1.25" of scrap metal
Really digging this cover Brad!

Had to do a little booty fabbing to shave the rear though.

I like mine also from Barnes4wd. Just need to test it out.

Looks great! You will love not having that lip hanging on every thing!

Could have just gone with a Dana 70 and not have to deal with the rock catching lip.

Want to talk about a rock anchor? I'm running an AAM 11.5! It's a smidge bigger than a Dana 80.

LOL! AAM 11.5 is def a MONSTER rear axle! Be interesting to see if they have any weaknesses offroad

I won't be able to say until I get done with my truck and actually let it see some wheelin' action! You have a PM about helping me with that

I had a D-70 but sold it. It was way too wide for me and I didn't feel like messing with it.

I'm gonna have a ton of money tied up in this axle. But, the pinion support and preload cups are similar to a 9". Guess there was someone smart enough at GM to admit that Ford had a good idea there

A removable, 3 bearing support, pinion and threaded carrier adjusters have got to be the best/easiest things ever used in an axle!

That idea was around before the time of the 9 inch with the Eaton axle which the 14 bolts are based on. I could be wrong I'm not sure when Ford put out the 9 inch.
