Why in the hell would you need 2.5 ton axles? Even with 44's you're never in a million years gonna even stress those. Just curious. Sounds like you're going way overboard unless your CJ is gonna be built like a dumptruck to haul around other people's rigs or something.

i can get the 2 2.5 axles cheaper than 1 front d60 used from a junkyard with 6.72 gears and i can shave them to have the same ground clearance as a d44. besides nothing is unbreakable and i was thinking maybe some used 48 inch tires would be fun to have

Its true. I know of a place i can get Rockwell 2.5 ton front for 450 and rears for 400. but im still happy with my 8.8 and Dana 44 for now.

dude if you really live in hell then you really need rockwells
if not then you just kinda need rockwells
all in all i think you should do it
don't let anyone tell you that your 44 is enough, even if it is you should still buy bigger stuff
why not?

I'm currently putting rockwells under my TJ, if you'd call it that. Anyway, the rockwells end up being 69.25" wide with the brakes removed and the hubs flipped in...about the same as full width 60's.

The biggest concern is the front axle and clearance. Since you remove wheel brakes most people put a brake on the pinion..which sticks up past the housing. They are tall, very tall. In my Jeep I've got the axle forward and the motor back...it should clear, but on a stockish rig I really don't know, I've been building everything around this.

why not?
because whats the point if im not breaking the shit im running. Just so I can say "Im running rockwells man" Besides I wanna go out and beat my Jeep. Im tired of always having it in project mode while my buddies go out wheelin.

Also whats the point of having some bomb proof axles when im still running the np-231? If the axles dont give then whats next? The transfer-case would explode. And id waaaay rather change out some axle shaft then some t-case parts. Know what i mean?

cj did you just buy a bolt on pinion brake kit or did you make your own? any idea how wide they are without reversing the hubs? i am thinking 4 inch springs soa with a 2.5 shackle reversal or somthing similar. i may even run chevy springs. still figuring out what im gonna do all i know so far is it will be an 82 cj to start with i am stretching the wheelbase and slapping a big block in and im pretty sure after getting the price of the 2.5 tons that they will be my axles.

Wagoneer Machine shop in Oklahoma has done this to a few Jeep that I know of. Ive seen them in action works great and is fawking sweet! They run 44 TSL on the axles. I know it will work on a CJ and a YJ for sure cause they have done it, maybe one day I can run theese axles.

I am pretty decent friends with the guy at Wagoner mentioned above, his is currently having problems thrashing leaves. If you choose to do this I would go link and coil or coilover, something that will allow for better approach and departure angles.

The pinion brake in that image is simular to his setup but they ad a gaurd to keep you from ramming the rotor into stuff.

$850 sounds like a good deal for a set to me, assuming they are still in good shape.

Totally true about shaving them, if you can do it, do it.

Actually thats not true. At CAL ROCS, i think that it might of been Brutus, or one of the other guys snaped a axel shaft right in half.

hey danial that was me that wanted to trade u the 2.5 tons, i would have loved to do it, but i took some mesurements and they just wont clear my oil pan at the moment, so i need to do some custom suspension work b4 they would work, which at this point im not capable of doing and i cant afford to have it done, so i will have to hold off, i called and left a message about that transfercase i still want it but u posted on here that it was sold so do u still have it, ohh ya and i have 4 inch spring over springs and i mesured and didnt have room for 2.5 tons, and jeepmangled is smokin crack they will not work in a yj or a cj stock, both the ones he was revering to were cjs for one and also they were severley modifyed to fit the axles, so with the axle and motor in stock location they will not fit

axle clearance

You guys are worried about clearing the brakes in the front, why? the steering linkage is behind the axle so just move that bastard about a foot forward, extend the frame in the front, on a cj project I've been thinking about I'm just going to build my whole frame around the rockwell's, I think leaf springs will hold up if you use a tri-link set up of some sort to manage the axle wrap. Daniel sells the 48" for $150! I cann't see why more people don't swap these in. Hey Daniel I saw on your wedsite that you guys are making custom rims for the 20" tires, can you guys make a 20" style Hummer rim? I think the two piece rim with the inner collar is perfect for those 48's.
