Ford 9\" or Dana 44 fr my CJ7?......

I am going to get "new" axles for my 82 widetrack CJ7. I've got 33's but MAY in the future go to 35's, no bigger.

I run 50% street, 40% sand dunes, and 10% heavy duty trails, and rockcrawling (when I get out west every few years). I will get F+R ARB in whatever I get with 4.10 gears.

Which should I choose? Rear will be high pinion, front standard. I will use current front outers including knuckle and warn hub upgrade.

Currie says 9" better, Dynatrac says D44 is better. What are pros and cons of each? Any reason for me NOT to use my current outers (in very good condition).

I am leaning toward 9" because of drp out 3rd member, extra pinion bearing, and little stronger overall.

Re: Ford 9\" or Dana 44 fr my CJ7?......

I assume you are talking in the front based on wanting to keep the outers that are in good shape.

Are you comparing a High Pinion Currie to a High Pinion Dana 44? In the front a High Pinion (or reverse rotation) is stronger. So, if you are comparing Currie’s High Pinion Ford 9” to a regular rotation Dana 44, the 9” will be better for clearance and strength.

The Currie High Pinion 9” actually runs 8.8” reverse rotation gears that don’t have the 3rd pinion bearing like regular Ford 9” axles have. The third member is made out of nodular cast iron which is usually only in the perfermance 9” rear ends. The convenience of a 3rd member is nice for setting up gears etc.

If the price is comparable, I like the Currie unit better. Slightly larger R&P, nodular 3rd member, CNC machined, good clearance, etc.

Thanks for the input. I think I'll go with both 9" unless I hear a good reason to consider a D44 instead.

Get a Dana 60s for teh rear and a high pinion 44 for the front.

If you take a Dana 60 from the front of an F350 you can build a Rear high pinion for your Jeep.

If you do rock crawling then a detroit locked rear is the way to go.

LOL,

well.. you'll be making both of the axles weaker with this plan.. a high pinion axle is STRONGER in the front than a standard axle and weaker in the real.. in fact, i have doubts that a high pinion 44 or 9" in the rear will hold up. I broke my rear high pinion 60 gears last year.
the debate over which is stronger d-44 or 9" is age old and the bottom line.. I've seen plenty of both break.
I have dynatrac axles and they are quality parts with good customer service, but I would never purchase them or currie axles... to much $$$ just for a name in both cases.
A hihgh pinion d-44 front will do everything your asking and you should be able to find a sjhop to build one for half the cost of either of the aforementioned companies.
and ARB's are the right choise for you as well.. whatever detroit does, arb does better.
