3.42 7-5/8" Ring & Pinion

[Jack_K]

I have a matched ring and pinion gear set. It's 7.625" but fits the 7.5" and 7.625" 10-bolt rears. Ratio is 3.42. These fit the 3-series carriers. Also have new ring gear bolts.

These gears are used but in great condition. $100.00 plus shipping.

I'm checking with Ralph, but that just might be what I need for my 78. Will send you a pm if so! Thanks!

I'll take $75.00 plus shipping. Remember, this is a 7.625" ring gear. It's bigger than the 7.5" but still fits the same carrier and rear end.

Anybody?

[jarheadJim]

Who makes that?

Do you have a good 26 spline 3 series carrier??

No carrier.

I have no idea who made the gears. There's no marking on either.

Ok, I can safely say that I have no clue about rear ends except what higher and lower gear numbers mean. So clue me in a litter if you would please? My rear is 2.41 posi unit. Will this work for me?

In case you need more info, my rear is a 10 bolt in a 82 Camino.

No it won't work for you as is. In order to use a 3.42 gear you'd have to change the carrier (your posi) or get a ring gear spacer.

There are ring gear spacers available (ebay for instance) that will let you use these gears on your carrier.

So, you need my gears and a ring gear spacer.

make sure if you buy a spacer it comes with longer bolts,,,

Ok, I really am clueless on rear ends. But I do know a little terminology for them. You are saying it won't work because I have a 2 series carrier. So that means a series 2 is 3.08 and numerically lower and 3.08 and higher is series 3, correct?

So in order for me to use these gears I would need something like what is on this eBay link?

To anyone upgrading gears....check first before purchasing! GM had an overlap between the "series." Mine had a set of 3.08's with 2 series carrier from the factory. The 3.42's are also available for a 2 series carrier aftermarket. Spacers would be ok if the gears were obsolete but otherwise should be avoided in my opinion.

I believe the 2-series includes the 3.08.

Everyone has an opinion and MINE is that the spacer is totally acceptable. What's the difference between a spacer and a thicker gear? Same spacing.

Sure, a thicker gear might be a tad bit tougher, but the thin gear is stock and used in the 3-series carrier, so what's the problem?

SAFETY! Longer bolts and two sliding faces(ring gear to spacer, spacer to carrier) retained by the same bolts. The ring gear is slight press fit on the factory carrier. The 2 to 3 series spacer doesn't have much of a "shoulder" for the gear to fit tight on the carrier. Sure it's the same spacing but why would one risk something simple like this?

I'm not an expert but Richmond Gear is. They don't sell them and don't recommend them either.

Jack K .....thanks for the PM to me about ruining your "potential sale"

I apologize and I was only concerned for the safety of others.
