ive heard of a shim thats used between the ring gear and carrier to space it out so that a set of 3 series gears can be used on a 2 series carrier. if this is true where can the shim be bought from? this is for a 7.5" 10b.

 

richmond makes thicker ring gears to use lower (higher numerically) gears.....if you havent already bought gears....I may be wrong, but I think the spacers are made for older 10 bolt and 12 bolts...

 

Richmond and some others still make the ring gear spacers for the 7 5/8 rear, they are pretty cheap and should come with the longer ring gear bolts that are required.
Like the other reply mentioned, the best way to do it is by the 3 series ring gear that is made for the 2 series carrier, that would be the way to go if you still have to buy gears. Hope that helps, Larry.

 

It's available at www.drivetrainspecialists.com except it's not on their page any more. You have to call.

Seems like it's about $50-60. Yes, they do come with the longer bolts; about 3/8" longer.

Lots of people make the "special" thick gears.

I'd go that way a long time before I'd use the "special" gears. Not that there's anything wrong with the "special" gears technically; it's just that, if you use normal gears and a spacer, then if you come up with the right posi a little farther on down the road, you can still use the gears you already have. Whereas, with the "special" gears, you're stuck with the 2 series crap FOREVER.

 

awesome thanks guys.

 

Awesome guys, SLP IROC-Z was actualy asking this because I just purchased a 2 series Eaton posi...and I need some gears now. He has a set of 3 Series Richmond 3.42's that i' will be buying.

Thanks RB83L69 for the link!! Your always alot of help. I will be calling them soon

 

I just gave DTS a call, he said $55 and it comes with the longer bolts.

thanks guys

 

Check ebay, i got mine from there, it was $35 i believe.

 

how thick are the gears. i just bought a 2 series posi. but the gear looks really thin. i have some 3.73 gears that i want to use and they look thick to me. if anyone knows and could help. thanks

 

3 series gears are thin and the 2 series are thicker. Thats why you need a shim to put a 3 series gear on a 2 series carrier.

 

If you use that spacer you will regret it for a long time, there is no shoulder on the 2 series posi to hold the ring gear, so you will be relying on just the bolts to hold it, If you have any power at all you will shear the bolts off. That is not conjector, that is fact.
The thicker gears is the only way to go and will last, so no need to worry about anything down the road.

 

how thick is the spacer? i am wondering because the guy i got my posi from is not sure if it is a 2 or 3 series carrier. and i am just wondering if i will know by looking at it or if i will have to measure it out. thanks
