Dana 30 reverse rotation? And Gear ???

Ok so I have a 95 YJ with the 2.5 and the D30 with 4.10's.

I am looking at switching to a XJ 30 up front with one piece, how do I tell if this reverse rotation issue?

Do I have reverse rotation now?

If yes, then I will still need them in the new 30?

If no, ok!

Also, Cherokee 30's are HP correct?

How bout giving me some gear names to research?

I am going to be installing 4.88's in the 30 and the 44 I am getting at the end of the month! I still drive my rig on the road but plan to have lockers in both, probably lunch box up front and what should I go with in the rear. I plan to run 33-35" tires


Thanks, im constantly learning more and more bout gears and what not.


95YJ 2.5 AX5 NP231 HP30 4.88 and aussie, 8.8 4.88 mini spool, 4" RC, 1.5" Boom shackles, 1" BL, 1" rear stretch, 36 12.5 15 TSL SX's, trimmed front fenders, bedlined exterior, comp cut coming soon!

Your existig D30 should be a HP, why are you looking to change the front end if you are going to stick w/ a D30. I also have a 95 that I went to 4:88's a few months ago, it made a big difference.

I can quit drinking anytime I want, but hey I'm no quitter :)

There really is no such thing as reverse rotation gearsets for a D30. They are either reverse cut or standard cut & rotate in the same fashion as standard cut gears.

Basically, a high pinion D30 (HPD30) has the pinion gear exit the differential above centerline. A standard low pinion D30 (notice I didn't type HP) has the pinion gear exit the differential below the centerline. So since the ring & pinion gear sets push against each other at different angles, the gears are machined differently & HP gear sets are slightly stronger because when going forward, you are "pushing" against the strong side of the teeth.

Yes, a YJ's HPD30 uses reverse cut gears.

It might be easier to swap in a set of axle shafts from a TJ or XJ & relocate the passenger side seal to the carrier. This is a very popular mod.

The front 30 is currently lincoln locked, and i think its gonna be less expensive to start over then to buy the new gears, long shaft, carrier/locker

Since you replied to a 6 year old post and not started your own and its your 1st post...

The 30 is a front and not good for what you want.

You want a Toyota corolla axle or celica rear axle back from the 80s or 70s./
You can flip the axle to change direction of rotation. they are short and STRONG.
Look into the legend cars

to the above... this is a 6 year old post..
