You can't just run your 3rd member upside down on a 9inch. You can go to http://www.currieenterprises.com/ They make high pinion 3rd members but use the 8.8 inch ring gear.

exactly what modifying would one have to do? i have a 9 inch and have thought about the exact same thing. i have also thought about making a custom front housing and using the third out of the rear--only upside down. i wonder if that would work?

You sure can run your third upside down, you just need to have some way to oil the pinion and ring gear weather it be external oiler or some other way. A lot of the mog9 manufacturers keep that secret, but check wngrog's pinion support with the oil passages.



...But thats not going to be your problem. Your problem will be the fact that you will be driving in reverse.

Do a search on people flipping their axle housing upside down for hi pinion. IT WILL NOT WORK, YOUR TIRES WILL TURN BACKWARDS.

Exactly, and nobody makes reverse cut 9" gears. Thats why currie uses an 8.8 gear. And a totally custom centersection to house everything.

Not to flame, but reverse cut gears DO NOT run in reverse...

thats why he said reverse cut, not reverse rotation.

Well since noone makes "reverse rotation" gears for anything, and we were talking about reverse rotation HP 9's, More than likely he was referring to reverse cut as running in reverse as most newbs think. I was only clarifying.

With a rear mounted engine, or portals, you can run your axle upside down with normal cut gears. Oiling is a issue though, well covered by wrngogs buildup

Personally time and BS don't equal doing this job yourself. Due to the oiling problems of the highpinion 9" its very likely you may have a problem someday. Thats why you want a warranty or the job done right. Just my .02

FYI - I am pretty sure they run a t-case oil pump, like a 231 or 241 or something, to lube the gearset in the flipped centersection. I have only seen this done on Mog axles.
