4.10's with a six speed question
Hey guys i was wondering what kind of rpms you are running down the road at 75. i was also wondering how much you guys like these or if you would of went with a different gear. Thanks

With 4.10's you should be turning about 2k RPM. You'd be turning less if you had the later tranny with the lower overdrive, but not by much. The 4.10 gears make 5th and 6th gears a lot more useful.

I have been running mine for years now, but I don't rev and dump too often. I do haul ***, but just don't launch violently. When I get a 9 inch, I will beat it up with some slicks.

I'm really interested in a gear swap for mine as well. I have a M6 with the 3.42's and keep thinking 3.73 would be enough cause I'm worried that the 4.10's would eat up the gas for a car that is 99% of the time street driven. Any thoughts on that? You guys that made the switch and still drive the car all the time, hows bad did it hit you in the wallet?
Also, how bad can it be, dumping the clutch with the 4.10's on street tires? I woudl think you would just spin like hell.

With a 02 m6 tranny the tach says 2k, I wouldnt want to go any higher. 93 trannies have steeper gears but I think the O/D are the same, but you would have to consult a tech artical.

They are great. Low 2k for 6th gear in the 70-80 range. One of the funnest mods you will do. I put it in 6th with them just cruising around town, so you aren't going to see a 5 mile per gallon loss or anything. I've taken it on a long trip with them, didn't notice any worse gas mileage honestly.

The steeper gears are usually weaker because there are more teeth needed to make the gear. More teeth means that each one will be thinner, therefore weaker.
The gear change won't change your mileage at all. All of the burnouts and fast takeoffs that you'll be doing while enjoying your new gears are what will kill your gas mileage.
Going from 3.42 to 3.73 wouldn't even be worth the money, IMO.

I have a 93z with the M29 and O.D. ratios are diff. than later models. .80 5th and .62 6th vs. the later .74 and .50. (I believe) I now have 3.73's and at 80 I am about 2300-2400. The M29 with a 3.73 is similar in overall ratio to a later version with a 4.10. I have thought of going 4.10, but don't want any higher revs on the highway. 3.73's work great. I also had 3.42 for a while which would be close to a later version with 3.73's. Only thing I don't like about the M29 is the gear spacing. The 94-02 versions were a closer ratio 1-4 than the M29, maybe due to CAGS.

Anymore opinions on the 4.10's vs. 3.73's in an T56? On here, sounds like most people lean toward 4.10's. I've talked to a few people in person about it and they say 4.10 will be to much and that my 1st gear becomes almost useless and the 3.73's would be better.

All This Depends On Your Goals For Car?
I LOVED MY 4.10 GEARS IN MY 10 BOLT . IT IS PERFECT FOR 6 SPD.. I WOULD NOT WORRY ABOUT GAS MILEAGE. WHOEVER BUYS MUSCLE CAR OR BAD STREET RIDE FOR GAS MILEAGE ANYWAY YOU SEE IF I WAS GOING TO HAVE AN ALL MOTOR MAYBE SOME SPRAY I WOULD GO FOR 4.10 ON 6 SPD. BUT IF YOU EVER PLAN ON BOOSTING IT 1 DAY LIKE I AM GET 3.42 OR 3.73. I JUST GOT 12 BOLT AND I PUT 3.90'S IN IT I THINK IT IS JUST LIL 2 HIGH FOR BOOST BUT IT IS CLOSE ENOUGH.
