4.10 down the road to match up with the 32’s and still unsure on the locker situation. May go full arb air if I can find a deal, or leave it open as it’s done me well so far. Likely keep stock shafts as I’d rather have that as a weak point short of the ring and pinion. Running the larger 760X xj u-joints. Will carry spare shafts of course. The bleepin Jeep overland xj built a very similar 30 plus IRO sleeves.What gears did you say you're gonna run? Locker?
Asking because at that point your well into dana44hd strength on the axle. Other than axle shafts and u-joints, it'll be bombproof.
