4.56 in a 10 bolt behind a 6 speed?

yay nay?

torque monster or 10 bolt krytonite?

[SlipStreamZ28]

Depends on what your trying to do, But I think I remember SS4Matt saying if its a automatic go with a 3.73 if its a manual go with a 4.11 . 4.56 might be a bit big for something you plan on street driving...maybe not. The 10 bolts on our cars are notoritously weak but I dont think you would have much to worry about unless you plan to start putting DRs and some mild mod's on it any time soon. IF you do, your either would want to get a 12 bolt or risk detonating your 10 bolt, However a cheaper alternative would be to buy a nice posi carrier with some larger spline axles, get a TA ( or simular) stud rear end girdle. Have the axle tubes welded in (they are just press fit as is) and have some brackets welded to the sides of the PIG. That setup should hold to about 400-450 rwhp depending.

Boom!

a 4.56 makes an already bad situation worse in 2 ways. One the pinion gear has less teeth and smaller ones which equals less strength. 2 the thrust loads will be tons higher cuasing even more trouble. Yes I prefer a 4.11 for a 10bolt but even those are on borrowed time with a sticky tire. Hell even a crappy wide tire could cuase convulsions.

i plan on sticking with street tires. opinion noted.

i can't think of any reason you would need that high of a gear...with 4.10's you are shifting a ton more as it is...a 4.56 would make things that much worse. unless you're running a tall tire drag car i see no reason to go further then a 4.10. especially in a 10 bolt!

i vote NAY

[kammi10]

i vote 4:10 otherwise good bye 10 bolt

i just want something thats gonna slam me in my seat I guess i dont see what the negative of a big gear is if 70 mph is still only 2300 rpm.

but theres a reason im asking people that have "been there done that"

[JoeliusZ28]

also sean, how much do you charge for a gear swap (if you do them at all)?

[iroc85blu]

i vote nay

broken 10 bolts are all to common. Especially with a stick. If u want that tall of a gear get a 9 inch or 12 bolt under it first. I broke my 10 bolt in my 00 ws6 vert a4 on 275 eagle f1's. Thats an auto car your stick really beats the rear end.

[JoeliusZ28]

quote from someone another site:

From my experience with (broken) 4.10's, it was the pinion that lost 2 teeth.

Consider this. The ratios 2.73, 3.42, 3.73, 4.10, and 4.56 all have 41 teeth on the ring gear. The pinions are what differ (15,12, 11, 10, and 9 teeth, respectively). IMO, there are equal odds of breaking a tooth off the ring for any ratio. I think the pinions are probably where the odds increase the lower you go??

Now a TRUE "4.11" ratio has 39:9 teeth, ring/pinion. IMO, the ring gear should be stronger, but again, the 9 tooth pinion may not be??

check my forum I have a winter special going and really for an M6 car you need to do it all. Otherwise you'll puke the 10bolt really fast. trust me this package is a good value. Keegorydah has been beating the living shit out of the 10bolt buildup i did for him. I am a bit surprised its lived this long.

Street tires will not slam you in your seat, a higher numerical gear will just spin them easier. unless you're just looking for 30-50 mph "roll races" i just don't think it would be wise to do that gear...
Trust me, Sean (keego) and myself can both tell ya that with street tires and a half way decent gear you'll just be spinning unless you get a drag radial and hook, and when you do hook, 10 bolt=boom. that's why i went with the 9" so when the time comes for some serious tire. i'll let hell lose with out lookin back!

well i definitely wont have that much $ before the special is over. Its looking like this is out of the question anyway. Id like a 4.10 but I almost dont wanna mess with my stock axle the way its been completely tolerant of the abuse the Spec clutch gives it. I think ill just continue saving for the cam instead. Also keegohs ten bolt has probably lasted because of the slipping clutch. A weak clutch isnt gonna shock a drivetrain the same way my spec will. (i know im preeching to the choir here )

[DETROITMUSCLE]

Well that gear would seem completly useless if you didn't run a sticky tire and in that case the rear would go boom. Save for a 12 bolt or 9" and then do a higher gear
