Im looking to upgrade both front and rear axles in my XJ, whats the best, price is not a factor. I am leaning towards the Currie 9inch but also am looking at Dynatrac 60. Anyone buy and use these, looking for feedback good or bad. Thanks
I dont want to spend 1500 per axle with new shafts gears and locker on a weak unit. Would rather spend more on a top quality axle and have it last. The 30 and 35 I have will break sooner or later, depending on use or abuse.
for 33s i wouldnt waste time in changing out the dana30, throw in some shafts and hd ujoints and ur good. For the rear i would get a 8.25 with 29 spline, or a dana44, maybe a ford 8.8. The axles ur lookin at are kinda a overkill for 33s in my opinion
Okay. Do you plan on larger tires?
With a limited slip in the front and 33's I dont think you will hurt the front anytime soon. 33's on stock 44 shafts would be fine as well, but a set of Superior 4340 shafts in a rear 44 even with the detroit will last.
I ran D-44 rear and detroit and D-30 with truetrac on 33's and 35's without a failure.
I installed a D-44 front and front detroit with the 35's and it worked fine as well. I stripped several teeth from the detroit and then started eating right front shafts, ujoints and hubs. Of course took a while to find out I had actually eaten the Detroit locker. Replaced it with an ARB, went to 38's with D-44's front and rear, 4340 shafts and CTM's up front. It worked well till I ate the rear detroit.
The point here is, with 33's a limited slip up front, the D-30 will hold. As I said before, a rear D-44 even with a detroit will be happy to handle the 33's.
If you plan on larger tires, 35s 37's 42's in the future, and money is no object, then get a set of custom D-60's made for about 3500 for the rear and 5000 for the front and never have to worry about it again.
