Like the title says, I have heard yes, and I have heard no, I have searched, but I have not found any info, can someone please help me out, and if they ARE available, in what ratio's? thanks for the help, flame suit on!:flipoff2:

Richmond gear makes the for Hi9 IIRC. but you need Hi9's case to use them as they dont fit in a regular 9" third.

Currie makes what they call a high pinion 9", though it's really more like 8.8" and are known to be weaker. Otherwise look at TrueHi9 and spending over $2k.

Really? Hi 9 is your only choice for a real 9" as of right now. You don't mean to say reverse rotation do you?

hi pinion, reverse rotation, reverse spiral, reverse cut, all the same thing just different name for it.

Like a set of D60 gears for a front high pinion, reverse rotation, reverse cut, whatever, I am not sure the correct lingo for it, but when the rotation is reversed then the gears would be on the cutting side, for a front axle, anyone? besides high9 and currie, I am not looking for a hybrid dropout, just a set of gears for a standard front axle, thanks again for the help.

What part of a 9" front is "standard"?

I don't know if they make reverse spiral gears for Hi9 or not, but I'm pretty sure they don't make standard low-pinions in reverse. The housing would have to be modified to accept and benefit from reverse spiral gears. The tooth contact may be better, but the thrust angle would still be on the wrong side of the axle centerline for that direction.

High 9.
And they only sell complete kits. They don't sell Ring and pinion only.

As far as I know we are the only people that made the investment for reverse spiral 9" gears.

Just like reverse spiral Dana gears don't fit standard Dana housings, our reverse spiral 9" gears don't fit standard 9" housings. :)

hi-9, the only choice and even the best choice if they weren't.

I have been eating ramen noodles for months but I'm glad I have my hi-9's ready for my build! :laughing:

Reverse rotation =/= reverse cut. If he for some reason wants his axle to run in reverse then it's different than wanting hp gears. And if that's the case, no one makes reverse rotation 9" gears but he could just flip the 3rd and get the same effect.

Step away from just reading forums... try researching for a change.

High Pinion, slang as the pinion is above the center line of the axle.
Reverse Spiral, What Dana did back in 65 for Ford
Reverse Cut, how the ring is cut.

Now, russellmn...
Please tell me what part of the axle travels in a "reverse rotation" as compared to a regular axle?

ok so I am understanding that there is not reverse cut gears for a 9" besides the hi9 stuff, this is for the 9" front axle in the 2 seater I am building, the 9" will be upside down because of the rear engine, the front will have to live with being on the coast side of the gears, thanks to all that have given input.

It won't be driving on the opposite side of the gears if you turn the 9" upside down. The real tops of the tires will be on the ground, and on the front end, when going forward, the real tops of the tires will be rolling towards the driveshaft/pinion which is the correct way for forward drive. Is that what this was all about? :shaking:

If you got a reverse spiral Hi9, that would be powering on the coast side because your drivesahft is now backwards with rear engine, assumiing you have the motor in backwards that is, and not driving off the snout, or had a special cam and reversed the firing order to run ccw.

If I'm wrong, seriously, please correct me. My understanding of all the terms used is referencing the same axle configuration. I know "reverse rotation" is a misnomer as nothing is "reversed", I was just stating various names people use for the same setup. As far as I know, all "high pinion" axles are reverse spiral and all reverse spiral are high pinion. Like I said, if I'm wrong please correct me.

I am just trying to get some clarity, when did the PBB become so fucked up, I am asking a simple question, if you guys dont like my question then dont read it, I am looking for help, not a bunch of ass hat web wheelers to waste time, we have SHIT SHAT for that, thanks to all that have chimed in and contributed,

yes its a rear engine, yes it will be running backwards, so the front will be on the cutting side of the gears and the rear will be running on the coast side of the gears, correct?

yes thats right - you cock whore you :flipoff2:















and i feel nude without my star - hope the paypal goes through soon :D

With the rear engine what you could do would be to run a Hi9 in the rear upside down to make low pinion again (yes that's an expensive low pinion 9") and a standard 9" 3rd up front upside down to make hi pinion (cheap hi pinion 9"). This wouldn't be very cheap, but would keep everything driving on the strong side of the gears.

russellmn, you got it.

Have to make sure us MN's get it right.

Easy there.... Maybe you should stated more infor in your orginial post.

Also, you've been around long enought to know if someone post they don't always need to add "x2" Sometime the best info is when people go back and forth on details.

WRONG!!! Your rear end upside down on the front will be running the right way. Turning it upside down makes it run backwards. Taking it from the rear to the front makes it run backwards to go forward. You turn an already backwards rear end backwards and what do you get. The right way again. A standard front end, be it hp or lp has the driveshaft turning ccw going into it to run forward. Your upside down rear end will have the driveshaft turning cw to run forward, the same as it does right now on the rear.

Edit: I totally missed the part about the Hi9 on the rear upside down and normal in the front upside down in your next post. You would be ok there. Sorry, and thanks for not drilling me on not keeping up.

cant you run both front and rear upside down then?

Jrod....If I remember right if your running a reverse engine you flip the axels upside down...

Sounds stupid but thats how the mud racers do it...



Also Mr.N knows his shit.,...

Jrod if you need more info I can send you in the right direction...Just PM me...

anyone care about the dates on this thread?:laughing:

the reason he asked is he wanted to run a low pinion in the front to clear his sump, as in the rear he has a strange 9" in the mogger - but when the axles find there way into his someday buggy he wants a 9" low pinion in the front


and the hi9 is out - as he is cheaper than me :flipoff2:
