I Have a 2001 Mustang GT with an auto and for my birthday my girlfriend is going to buy me 4.10 gears and have them installed and was wondering what all that i needed for the install. any help would be helpful. my 01 has 45000 miles on it.

to be safe go to mustang tuning and look at the rear end rebuild kit. i just had 4.10's installed in my 01 GT automatic about a month and a half ago. i have had no problems and they do not whine. i got the motive gears with the master rebuild kit which is like an extra 90 bucks but good insurace for the future. oh and the gains are awesome

i want to go with ford racing gears will the motive rebuild kit work with them. i know this is probably a stupid question but i said it anyways. what kind of rearend oil would you get

Take it to a reputable performance shop in your area. They should have everything you need from gears to shims, etc. Usually if you buy gears from them (more expensive) they'll cut you a break on the install. Don't buy anything until you talk to the shop.

I wouldn't go with Motive. They are divided half and half it seems...half whine half don't
