I am getting ready to install my 31 spline setup and also my upper and lower control arms this weekend. While i have everything out i was wondering about changing my gears. I have the 3.73s in there now and wondering about going to a 4.10. I have a 5 speed manual, and the 4.6 to 5.0stroker kit. i also am going to be running the nitrous and i have just put the new nto5rs on so this thing should hook up. I am running 2000 or a hair below at 60 now in 5th. Is it going to be worth the change or should i stay with the 3.73s.

 

I will never go any higher than my 3.73's with a 5-speed trans..

 

If you really don't mind the higher rpms then it wouldn't be so bad. I personally wouldn't like the high rpms at interstate speeds. I don't think you will see that much of a gain by going with the 4:10s over the 3:73s but I've never driven with 4:10s.

 

as has been said in a million threads, a million times...

4.10 for automatics, 3.73 for manuals for street use.

 

I can't see spending the cash for new gears for such a small change from 3.73 to 4.10s.

 

yeah, but the situation is slightly different. 5L stroker kit, nitrous, tires. Thats the only reason I responded, I get tired of the "what gear should I get threads" too.

 

Sorry i see these post all the times also...but the guy that tuned my car said that i could possibly go to the 4.10 but i want to make sure i am crossing the finish in 4th gear. I dont want to be running out. Also with the stroker it seems like i am running slightly lower rpms then when i was stock.

 

What ever happend to suggesting a 3.90......lol

 

what happened was the only companies made make a 3.90 for the 8.8 couldnt seem to make a quiet ring and pinion gearset. Dont know if thats still the case these days though.

 

3.73 for auto and 4.10 for auto...your going to loose your first gear with anything over 3.73's

 

Ok well i see that on AM ..richmond and motive both make a 3.90...whats wrong with it?...better top end but still a hole shot right? I hope to upgrade soon ...ive seen videos on utube for the 4.10 top end ,but not the 3.90..any advice?um plus i really dont care about a quiet gear noise ..as long as it works ..i already have longtubes and a slp full length exhaust...soo noise isnt and issue ..lol..um also im running a manual..If i haft to il start in 2nd ..lol

 

Ivee decided on the 4.10..But i have a stick and i dont care...

 

yes it has been said 4.10 for auto and 3.73 for stick

but if you plan on putting a power adder in the future go with 3.73 if ur an auto

 

But it's worth it from 3.27 to 3.73 on a stock GT?
