i have a 2000 xj sport with tha factory chrysler 8.25 rear end with 3.55 gears and iv been thinking bout putting a dana 35 in tha rear and putting 3.73 or 4.10 gears in it either way im going to put better axles and lockers... is this a good idea or not

 

keep the 8.25 in and put new stuff in the 8.25. its a better axle

 

X2 upgrade the 8.25. Much better than the Dana 35 rear

 

I'ld keep the C8.25. The 29 spline C8.25 is close in strength to a Dana 44 and stronger than a Dana 35. If you wanted to upgrade try and find a Dana 44 out of an earlier XJ since it will bolt in, otherwise look into a Ford 8.8.

 

thanks everyone ill keep what i got and look for a dana 44 or a ford 8.8

 

No get a 35 join the dark side of the force...........lol

 

what locker would yall go with it tha 8.25

 

Not many options available with the C8.25 I'm having a detroit put into mine right now, but I think the only other one is an ARB. I would have gone the ARB but its a lot farther out of my price range of what I wanted to spend.

 

yea tell bout it there all high

 

Well, my whole 4.11 gear change, chromoly rear axle shafts, detroit rear, spartan for the front is a little more than I wanted to spend, but costs a lot less than the gears, two ARBs and air pump like I would have preferred.

 

D44 and 29 spline are pretty comparable, the only benefit I see too changing an 8.25 for a d44 is semi float axles.(bolt in, no c-clips) after having to remove my locker 4-5 times to pull axles, it would almost be worth it to me.
But much easier to throw a locker in what you have and be done. I use an Aussie in mine and its great.
If you want an actual upgrade than go 8.8, stronger than both

 

If it was'nt for that beautiful Turddy Five I would'nt got my truck for such a good deal!!!! The guy thought it had tranny problems..sounded like the whole back end was going to fall off!! LMAO One hundred dollars for the 8.5 at the u-pull it

 

im just going 2 keep the 8.25 in and put a locker in it...what locker would u do up front in the dana 30

 

Absolutely the way to go with your existing axle. With the Dana 35 you'd be going backwards in strength. The Spartan locker is great for the Dana 30 which is what I have. It comes with the new cross pin and it doesn't require reuse of the original shims. I have an Aussie in my 8.25 and the Spartan was easier to set up. Bigger Springs too. The Spartan is a better deal since the other lockers don't include the cross pin which is around $25 by itself and most of the time it's free shipping.

 

Lock Right up front Aussie in the rear.Heard good stuff bout the Spartan up front from buddies that have em.
