I just bought some richmond racing 4.10 gears, is this a good ratio? will i be happy with the acceleration?

I don't have any opinions if its a Auto, but I'm really happy with them in my M6 car.
Its such a difference over the 3.42 you wouldn't believe.

I ran 4.10's in my 94 w/a T56 and loved them....swapped the tranny to a 700r4 and the 4.10's were a little too much gear for a DD. Switched to 3.42's and they were better for driver duties but were not enough for drag duties. I am now running 3.73's and 27" tires on the 94 and 3.73's and 26" tires on my 95 w/a 4L60E.

cliff notes
4.10's are good for a T56
3.73's for a drag oriented A4
3.42's for a spirited daily driver A4

I thought that 3.73s ran fine on a daily driven a4? Thats what I was planning on getting here soon

not much difference but I liked the 3.42's better if I was going to drive it every day...for a drag setup or frequent racing go with the 3.73's...I have them in both of my F-bodies right now

I had a buddy put a 4.10 gear in a mostly stock 97 TA and it spun bad on street tires, very, very bad.

I used 3.42's in my a4 383 LT1, I liked them, I thought about 3.73's but that changed when I got the ls1 with 6 speed. I kept the rear and thats going to get 4.10's

BUT for highway cruising I dont like spinning above 2k @ 75mph ave, im not rich lol

im at 2100-2200rpm at 65 or 70mph... cant judge good.

A T56 and 4.10's is a perfect pairing because of the .5:1 6th gear
5th in the T56 is .73 and 4th in the 4L60 is .7...so to give you a good feeling of how 4.10's would be in an auto ride around in a M6 in 5th gear

I had 2:73s and got a 4:10,all i can say is Shiiiii........

Yeah that is a crazy jump. My mind was blew away when I went from the 3.42 to 4.10s, that was the first time I've had a gear swap in any of my cars.

Yep I love the t56, at 75mph your barely turning over 2k.
It takes way less effort to accelerate, which is where you use most fuel, not while cruising, so if you could control your right foot, gas shouldn't be so bad, I haven't noticed a difference yet, can drive for about 4 1/2 hours before stopping for gas, burn about 12.5-13 gallons in 4 hours or a little more.

i run 4.10 gears with 315 tires and i can never get traction. Daily driven.

well with my 4.10s, if you paid me for gas to ride around in 5th on the freeway then i would lol. i use 6th on the freeway and still get

i still miss my 3.42s, so i can drive on the freeway and sit at 1500rpm. and my gears would last longer.

to everyone with no traction: same here, when turning and on the gas i powerslide no matter what. especially in rain. when/if there is any

but on a drag radial rolling into first gear and through a quarter mile, it is just about the greatest feeling my bolt LT1 has ever had.

ps when you have too much power, 3.73s are fine with a t56. my friend's 74 nova with a 383/t56 does just fine

My friends are impressed when i loose traction turning out of my driveway going like 5 mph. After traveling 2500 rpm on the highway in my automatic, i realized this is a low cruisin or strip car. So what do i do? change the gears? nah i bought another car to drive to work.

a 9" would be great. 2 center sections. 1 with 4.11 or 3.90 and 1 with 3.50
