body shops dont normally do gear installs ....
2nd you really dont wanna skip out on gears ... i say pay for the better ones, thats one thing you never do is skimp on upgrades!
if you cant afford it right now then just save its the best thing to do, because if you dont already have trac lok, then youll definitly want it, and if you already have it im sure youll be fine without replacing it your vehicle is fairly newer so.. just gears will be fine,
and for gears i would suggest Ford Racing gears, they are what i have and are very quiet.
motive gears too
