I've always had the worst luck with Richmond. Wouldn't rank the rest but would say after doing many gear installs, I try for oem used or oem/nos gears above all else if possible.

Thx. I will be using 4.10 ratio so OEM may be tricky - glad to hear others have had the same Richmond issues.

I have a Dana 60 and had a bit of a hard time finding a 4.10 as well. Ended up putting -wanted- ads on Dodgecharger.com and moparts and had what I needed right away.
(was much easier than watching ebay for a month)

Nobody's gears are as good and as consistent as they once were. US Gear and Motive seem to be the best options now. Richmonds are awful. I've seen some failures of those over the past few years that just make you shake your head.
If the results don't match the theory, change the theory.

Richmond and Motive 742 casting gears are identical.
Other than the pinion spline count, Richmond and Motive 489 casting gears are identical.
They are both made in the same factory in Italy on the same machinery.
Motive's 9.5 gears look like jewelry next to a richmond. Are they made there as well?

Used a Motive street gear Dana 4.10 in my race car. It was quiet coasting with engine shut down. It lasted 400 passes before bending the teeth. The no name replacement set only went 125 passes before shattering pinion teeth. Car has been 1.25 60ft at 3350lbs. Now has a US Gear pro gear. Doug Wow, what is the rest of your combination?

There is a nice writeup about Doug's car on Dragzine I have used Motive gears on different rears and they all had a great pattern and were quiet on a few street cars I have done. A few more I have built are in drag cars so I don't know if they are quiet or not but they are 9 inch Ford rears and still getting beat on all season. I used the Summit Racing house brand gears when I had a 9" in my Savoy and they were the Italian gears made by Maserio ? They were 4.56 9-inch Ford gears and it was a very nice set and they were very quiet for 4.56's Gus

I would be surprised if they weren't. Most of the stuff I see is 9" and I've seen some ugly Richmonds the last few years. Broken (shattered) teeth. gears that look like someone took a disc grinder to the contact area. I assume these guys are putting actual gear lube in their rears.
