whats the difference between the high pinion reverse cut dif they used from 96 to 99 and the low pinion standard cut one that was used in 00-01? im kinda new to solid axles and jeeps in general. main reason im asking this is because i have a 00 and i was trying to use the transfer case and front drive shaft from a 96 with my lift because it has a sye already installed. wondering if this will work with ok the newer axle? im guessing since its lifted i would want the high pinion from the 96

 

All XJs had the HP30 until 2000.

Yes, you want the HP.

It brings the pinion gear up towards the top if the ring gear, allowing for more contact of the teeth, as well as higher clearance under the truck.

Imagine drawing a circle with a line horizontally through the middle. That's a basic low pinion design. Now take that same circle and line, only place the line through the top 1/4 of the circle. That's the basic design of a HP setup.

 

aiight that makes sense....n its reverse cut cause its opposite side of the ring gear...

 

the gears are "stronger" because the force from the pinion is acting on the convex face of the tooth

basically

reverse cut --> (

standard --> )

 

no thats a misconception

 

Standard cut


Reverse cut

 

ohh ok thanks for the pictures that helps alot

 

no problemo man.

lots of people think that because of the "reverse cut" that it spins backwards, or that because the axle is "flipped" to run up front

 

yea that was the first thing that came to my mind as well
