hey guys i certainly dont know much about performance upgrades but i ve been reading along the forums and i ve seen that you guys talk a lot about t-lock and gears sucha as 3.73 and 4.10 i need to know what would be best in 4.0 stock v6 mustang like mine.....i really want a better performance without losing hp or any power.............please include where to get them and how much for them and labor as well.........thaanks guys for the sharing the knowledge.......

 

do you have an auto or a manual?

 

i have a manual

 

Better traction: T-LOC (stock one-leg axle sucks)
Better acceleration: 3.73 gears (if you do lots of highway driving)
Better acceleration:4.10 gears (if you do lots of city driving)
Best acceleration:gears AND T-LOC

You are no going to lose any performance with any combination of these mods. But will work harder on the highway with either set of gears.

I added to T-LOC and kept the stock 3.31 gears because I do 90% highway driving and 2 MPG for me adds up to HUNDREDS of bucks a year (1 year old pony 43,000 miles).

Ripping a 150ft burnout looks cool on the street but sucks at the track or trying to just get into the flow of traffic in the rain!

T-LOC is excellent choice, but you can add a gear swap with no extra charge at the shop (the gears come out when you put in the T-LOC anyway).

SOHC

 

americanmuscle.com has motive 4.10s
" " motive bering kit also needed
discount code is "mustangboards"

you will need a tuner if you dont have one, talk to justin at vmptuning.com

tlok at stangmods.com
or
detroit true trac at drivetrainspecialists.com

 

awesome guys this was very helpful, but how about price wise...........?

 

whats the difference about this two gears guys 3.73 and the 4.10 performance wise besides that one is for city and the others is better for highway.........how about the shifting is it more rough or is the same???????????

 

the reason one is best for city and one is best for highway is cause the older folks are stuck back in the 70s with pushrod motors and a 1:1 final drive, on a SOHC 4.0 with a .75/.68 final drive there arent any problems with them on the highway unless you drive on the autobahn everyday

4.10s NA/sprayed/centris as for the roots and turbo guys, cant help ya sorry

 

I think price is like $400 for parts then probaly 200-300 for install. like others said if you do one, I would do the other as well because labor price should be the same either way.
