Richmond 4.10's exploded in mine. Then I went to Motive 3.42's and they held enough to kill an axle shaft.

Breakage has more to do with setup and other modifications than it does with gear brand. Plus it is not always the gears. I would say at least half of the people who bust a 10 bolt do so in the differential or axles.

Never snapped my Strange Axles - but I have busted 3 sets of gears though; stock, Motive, and whatever DTS put in my latest 10 bolt...

Ford 9 inch - the solution to my 1-2 shift issues!

the poll is deceiving. a lot of people choose motive gears so naturally, it's going to be the highest in the poll. that doesn't mean they're the weakest; it means they're the most popular.

I would like to see how many are stick cars and how many people installed there gears. If they were proffesionally installed did you tell the installer? We set backlash tolerances tighter for hard driving at the track and stick cars. The backlash is the slap of the gears and or mesh tightness. Plus set the gears in a slightly more competition pattern set-up . Hope you all have better luck out there. Jim

What company do you work for that you know so much about gears and setup. Not being a smartaXX just trying to get a little background.

Default rediff builds

I have my own company in akron ohio area.

J D Race and Restoration. I did not want to over advert...seems some forums have rules or just plain do not like people pushing there products on the forums. So trying to stay low key, but still answer some questions when I have some time. Try to get a pulse on what the guys are needing out there.


We specialize in GM muscle cars rears. I have a website I am trying to get moving for information on GM rear diffs and any rear diff questions anyone might have. It has classified section too. I am slowly building the info as my nephew is building it and have to work around a college schedule ...lol. Education first I told him . If he gets time we work on it.


www.jdrace.com

I do not claim to know everything and will not give a BS answer or a guess. If I do not know I will say it, But will try my best to get that answer too. I have learned from many different racers and spent many hours wrenching and disassembling all kinds of GM diffs. I started the business from nothing and narrow custom rears if needed. I have alot of hands on infomation so if you need help try me I am always willing to help out. Jim Mitschke

Any interest in the MOSER 12 bolt rears? I see everyone is going 9" That is a shame... I have to stick with GM . I can try to work out a better price and build using these housings (12 bolt moser) if any of you are interested. They will still be expensive but should be able to get them lower that 2000.00 GEEZ...

Brand doesn't matter in the 10 bolt. It's the simple fact that there's only 7.625" of room to work with. You can only fit a limited amount of beef in that can. And it's just not enough room to put in enough metal (big enough parts) to hold good power.

It doesn't really matter what brand you get. IMO 4.10s in a 10-bolt isn't even smart if you do anything at all besides fairly easy street driving because they break easy enough to start with.

i broke a set of richmond 4.10s and im now on motive 3.73s, i saw summit racing had there own brand of 4.10s i dont know how strong they might be but for 125 bucks im willing to find out.

Hey monzaz, like how much tighter do you set youre backlash? and does it cause any gear noise? or premature gear wear?
