4.10's
 

I have a 99 TA m6 wanted to know how much these gear's will change the car. I have herd that it a hole difrent car

Yes it will. As long as you have a 6 speed.

They are one of the BEST mods you can do to your car, regarless of additional mods or power output. In a 6 speed, the 4.10s really shine and help the motor move the car down the road! Let us know if we can help with install!

I miss my 4.10s....but I will have 4.11s soon in my new rear (broke my 10 bolt)

mmmm 4.10's . . . wish my car wasn't a dd so i could get some real gearing in there

How likely is it to break your stock rear-end using 4.10s on regular street tires? I've heard 4.10's and drag radials it is really easy to get a dead hook and break your stock rear end. Ever since I heard that I didnt want to get them but if any of you guys can say different it might change my mind lol.

Were running a special on 4.10's & 3.73's right now!!

i think the 4.10's are a little weaker than 3.??'s, i seen somebody talking about that, i think they said the 3.??'s spline is a little bigger than the 4.??'s, also seen something on 2.73's being stronger than 3.??'s, i dunno, i could be talking out my @$$, i am just trying to remember

I have 4.11's in my Ford 9". Trust me. You will want those gears. Im all bolt ons and the gears are what makes that car move. If your on the stock rear end...I would just save for a new rear instead because 4.10's will break it. I DD mine and its not that bad at all. I drive on the 408 and turnpike Monday-Friday and I still will get 210 miles on a full tank. Then there are days when I will get on the car and I'll get about 130 or 140...but hey I didn't get the car for economy. Get the rear and get the gears you will not be upset I guarantee it.

a ford 9" takes a lot of hp to turn, about 45 hp . thats alot

Gears will make a big change in the car. 1st and 2nd will go by much quicker, but if you are thinking long term a girdle and/or aftermarket axles will help the 10-bolt live a bit longer. If you're considering upgrades, doing them together saves labor time and money.

A 9 inch, 12 bolt or dana 60 will all chew more power than the 10 bolt due to rotating weight, but they are much stronger when built right.

well I am goning to do bad ass heads a big cam roller rockers zo6 intake headers cat deleat 90 mm throttle body and a zex kit for a 50 or 75 shot. shood put me around 525-550hp , forgot a tune!!!!!!!!!!!!

If your planning the mods your saying, your going to want a stronger rear. Yeah it takes more to turn but its better than breaking your rear at the track.
