V6 Rear end Gears. 3.73 or 4.10
I'm looking to get teh 3.73 gears in my stock 01 V6. I was wondering if anyone knew the basic gains I could expect? Also if it would be worth it to get a Tlock as well? I am going to get the SCT SF3 programer and royal puple oil i think as well. does anyone have a guess as to how much it will cost to get installed? Or can it be done in my garage with simple hand tools?

better off the line acceleration, about half a second in the quarter mile
tloks are junk, my car is on its 3rd FRPP diff, and all i have is intake/exhaust/tune, im going with a detroit true trac when the tlok thats in there goes out
i dont like synthetic in the rear end, i run straight GL-4 gear oil

do you have an auto or a 5spd? The popular choice is 4.10 for the auto and 3.73 for the stick. Personally, I was going to get a 4.10 for my manual (driveability be damned lol), but they were hardcore backordered so I just went with the 3.73's (still waiting to be installed ).
I wouldn't really suggest a tlock; they can withstand up to 300rwhp, but they tend to break at stock power... a lot. It's hypocritical, but I have one (still waiting to be installed), but mine is just to get me through this winter; I'm going to be looking for an 8.8 rear end and a TrueTrac this summer.
And yeah, gears/lsd can be installed in a garage with (I believe) hand tools, but I wouldn't recommend it if you've never ripped apart a rear end before; from what I've heard, the spacing is hard to get right and requires a feel for it. If you don't space it right, you risk having gear whine and you could more or less destroy the rear end. I'd recommend just having a reputable shop doing it... it's what I'm doing (but I just don't trust myself lol)
*edit: also, remember that your cruising rpm's will be higher with 3.73's or 4.10's than they will be with the stock gear.

I don't know if it'll be better, but I know it's a pretty popular choice for guys with auto's. But gears just don't increase off-the-line acceleration, they increase acceleration throughout the rpm range, so highway acceleration shouldn't be a problem. Just remember that 4.10's will reduce your top speed a good bit (I think the theoretical top speed of a manual with 4.10's is something like 125 compared to the theoretical 140 of stock gears), but there's really no reason you should be going that fast anyway
But either way, I'm sure you'll be happy. Even the 3.73 is a big step up from the stock auto rear end gear (I believe the stock rear end is a 3.27).
I'm just going by what the 3.8L Modifications sticky says
