Ford 9 Inch Ring and Pinion Gears

[mustang7173]

All,

I am looking into buying a 9 inch ring and pinion gear set, 3.55 or 3.60. I have seen all kinds of reviews and forums talking about Richmond gear, Yukon, Motive, USA Standard gear sets. I have also seen price swings of approx. $100.

Yukon and Richmond approx $265.00

USA Standard $165.00 Do not use if car is to be quiet.

So, I am asking for feed back on what you folks are using. Let the recommendations begin.

I have Yukons in my '80 Jeep CJ-7 - can't say anything bad about 'em, either. They went right in, the installation kit was top-notch, and no noises or issues to speak of. Had 'em for over 10 years, although very low miles since I don't drive the Jeep much anymore.

Of course, they're 4.10's in stock AMC Widetrac axles running 33x15.50 Super Swampers with Detroit lockers and hardened axles. The thing is a beast and will go anywhere... as long as there's a gas station within 50 miles.

I've heard lots of good things about Richmond gears from my buddies who 'wheel the crap out of they Jeeps and nobody I know has ever actually broken an R&P set... usually, it's the axles that give up first.

Hope that helps.

Check roushyatesparts, they have used NAPCAR parts for a great price. Their gearsets are deburred and polished high quality sets with tons of different ratios.

I bought new Motive 3.25 gears. A little bit noisy but strong.

I have had quite a few differential professionals tell me that the original Ford gears were the best gears ever made, if you can find nos parts. I had motive swapped in for 3.25's. they made noise. And they were set up by the guy in San Bernardino who supposed to be one of the best in the business. Bill Thomas is the name.

I just put a set of Richmonds in my other car. After like you reading a ton of reviews.

Spend the extra $$$ for the Richmonds or something other well known name that is made in USA.

Watch some out because some well known brands have an imported line also.

I went through this with my Model A and do not care to repeat.

Thanks. Jay

I just sold a set of Ford Racing 3.50 gears to a guy who had installed a set of Motive, he said they were very noisy which is why he bought mine.

Nothing is as quiet as factory Ford gears. Yukons are pretty close, but run a hundred bucks more than cheaper gears look for a 3.50 ratio (BTW 3.55 is an 8.8 ratio)

I used yukons for my 3:89s. The guy that did them said that Yukon specializes in off road 4x4, and if they last long in crawler they'll last long in pretty much anything. I also heard some good things about Richmond

I have Richmond 4.11's in my car. Never noticed any noise from them, but that is maybe because my car is already pretty loud.
