I disagree. My 4.10s pull harder than my 2.73's did at any rpm and/or speed. A 2 gear drop with 2.73's is roughly the same thing as a 1 gear drop in 4.10's, both will land you at about 4000rpms right in the meat... The 2 gear drop of the 2.73's takes longer too...

4.10's are better gears for stop and go acceleration youll toast other stock f-bodys with there 3.73's and under

Any recomended brands, I was looking into getting the 4.10's from Pro Tech Engineering there out of some parts catologs couldnt find a website but they cost 149.99 free shipping!

thats a pretty good price for those gears are you sure thats 2 series gear i really dont know about the quality of them.i got richmond the do whine but they are some of the stronger gears out there.they are like 190. or somewhere around there.

I have 4.10s in my A4, and love them. My dad has 373s in his z and on the highway we cruise at almost the same rpm, the reason being i have 18's on the rear. But from a stop the gears will pull like crazy. Go with the 410s you wont regret it one bit.

yes series 2 carrier

Few months I intend to go CC306 with 1.6's and a stall too that will be the next mod after my 4.10s

If you are seriously looking into doing a gear swap, I highly recommend the Thunder Racing gear package. You get your choice of gears, a t/a girdle and stud kit, install kit, fluid, and additive.

with 3 series carrier, they are $400 total, and with 2 series carrier they are $435 total...

I'm more conservative and I would say 3.73's with an auto. I like the shift points and they way it carries 2nd gear.


Jason

whats the deal with the shift points

the higher your gear ratio is the faster it will shft through the gears.

Unless the're putting 500 to the wheels

Like if im going i guess about 40 or and punch it it takes about 2-3 seconds before you feel the powerband come in to play or like a flat spot nothing that slams you back all over again, but how would that feel with 4.10's compaired to 3.73's

The 4.10's are installed!!!

I can't tell you guys much about how they work yet, because OF COURSE, it's raining!!!

What I CAN say is this:

• They're Richmond 4.10's, built for a 3-series carrier (originally a 3.23 diff).
• They only whine a little bit (hardly noticable) on acceleration. Not even half as bad as my 3.73's whined last year.
• They do not whine at all while cruising or decelerating.
• At 80 mph, 4th gear and lock-up, the revs are about ~3100 RPM!!!
• Under light acceleration, the transmission is into 4th gear and lock-up by about 40 mph!!!
• Even in the rain, traction doesn't seem all that bad surprisingly, however I just got new tires on Friday.
• I can't wait for some dry roads to really try these out.....I think they're going to haul a$$ off the line!
• I really can't wait to get to the track.....I'm going to get E/T Streets this year, so hopefully 1/4 times will drop a lot.
