busted? i was comparing 3.73 to 4.10 like i thought you were. you should just stop posting. you're not helping your case. you quoted what i told him to get. i said to get 4.10 and that the 05 had 3.55 stock. how is that comparing 3.73 to 3.55 and 4.10 to 3.55? ok, i think i'm actually getting dumber replying. this should be it. love ya!

 

Man you guys, i was just wondering the differences between the 2 ratios so i would know what to buy, that was answered long ago so just let the thread die. P.S. nanaki probly gave the most help out of all of you.

 

I recall a most that JD made where he posted the gas mileage from his road trip with highway driving using his 4.10s, and his gas mileage wasnt bad at all. Maybe 1 or 2 miles beloew what you got before, but thats nothing big, and if you drice it right your not gonna be gettin that bad of mileage, JD proved that wit his logs of mileage he posted.

 

I am also thinking about putting 4.10s in my 2000 Mustang GT auto trans...but Is it a significant loss is gas mileage?

 

well never mind I guess I should've read more lol
1-2 isn't that bad...well worth it from what i hear

 

To chime in for the sixxers in the crowd-

GTs come with a stock 8.8" rear end where as pre 2010 V6s have a 7.5" rear. IF anyone with a V6 wants to do gears and serious power adders, id highly recommend they buy a complete rear end assembly including a 8.8" rear to handle the extra power.
