i was looking into T-Lok and gears but idk which to get because partially i dont understand the difference. for the T-Lok there is a ford 8.8 31 spline or a 7.5 with a 28 spline the only difference is about $70. and with the gears there is a 4.1 and a 3.73 they are the exact same price i just dont understand what the (pardon the ignorance) numbers mean..and also i am assuming i have a 7.5in rear

[05horse]

you need the 7.5 inch 28 spline its for the V6

3.73 and 4.10 are diff ratios

the higher the number the faster you get off the line and in to the powerband..


for a daily driver i reccomend 373's

for a weekend warrior 4.10

a t lock makes both wheels spin instead of one

[05horse]

oh basicly the higher the number the more RPMs it takes to spin the tires one time


do a search on gears... that snd mufflers are prolly the most common threads on here...and the what should i do next? threads lol

[Jake516]

ok thanks..and i need a little more help on the gears..because im sure like everyone else with a mustang..i like to take of fast everywhere and hear it roar..but it is a daily driver??? so 3.7 or 4.1

if your stock gear is 3.31 id say 373.


i got 3.73's and im glad i dident buy them
then again i do a ton of highway driveing


but 4.10s for a city car, occasional or lite highway would deff be a kick in the pants!


they must be installed by a pro. i paid 300 for an install

but some ppl pay wayyyy to much!

[Jake516]

well i rarely drive on the highway and if i do its no more than 15 min..and $300 for real?? thats more than the damn T-Lock lol

[05horse]

its expensive but my fav mod

220 t loc
159 gears ( motive) ppl say they whine but mine dont.
75 for bearing kit ( safe insurance while your in there )
300 install

30 500 mile oil change

[Jake516]

so i need more than just the T-lock and money for install? lol. and what about and underdrive pulley?

under drive pulleys... ehh for the price id pass


u dont need the bearings and you dont need the 500 mile oil change... its just safe insurance.

[Jake516]

159 gears ( motive) ppl say they whine but mine dont.
Dont know what ^ that means..and what would the bearings do and 500 mile oil change? do u just change it every 500?

motive is a brand

i love mine but alot of ppl dont like them

motive makes gears for Ford. but they are made in italy

ford gears are made in usa but cost mroe


bearings are what turn in the rear like wheel bearings or bearings on a skate board. theuy are bearings.

new ones are safe insurance that one wont go bad soon.


no after 500 miles of new gears ( break in period ) you should change the oil to get what dust, particles, gear wear has come off out.


not required but reccomended.

[05horse]

i plan on changeing my rear oil in 20 thousand miles again

[Jake516]

Oooooooo. lol ok thank you for the clarification. and i will look into the bearings and definitely change the oil. and depending on the mpg drop between the 3.7 and 4.1 i will get the 4.1 (only because i like taking off fast =P) but parents didnt want me rockin the v8 =( haha

[05horse]

4.10s will def get u closer

gears are my fav mod.

usually witeh 3.73 ull drop 1-2 MPG and with 4.10 2-4 MPG

but if u dont drive highway like 40 miles one way each day ull be ok.

esp if ur an auto

autos love 4.10s!

[Jake516]

yep im an auto..so sounds like 4.1 is for me
