Full 8.8 w/ 3.27 gears & TracLok. It has the North Racecars 5-Lug Fox length axle kit with Cobra caliper brackets and OEM Cobra rotors. These axleshafts MIGHT have 20 miles on them so they are literally still new. The Mustang is a project and doesn't get driven a lot. Not sure how many miles are on the rotors because I got them when I bought my IRS. As far as the axle itself, the axle seals & outer bearings are only a couple of years old and the internals on the diff are in great shape. Diff has about 180k on the ticker. TracLok still works. Was rebuilt about 6-7 years ago by me. I think the Pinion seal on the diff needs replacing. It wept a little when I pulled it from the car. Just filled it with fresh Mobil1 when I installed the axle kit. The kit from North sells new for $370. I'll take $300 for the entire axle (local pickup only) or $250 + Shipping for just the axleshafts, brackets, & rotors if I need to break it down. I need this thing gone. It's impeding my IRS install. Item located in Portsmouth, VA. Thanks!
