Hi, I do all my own work, so I son't know for sure how much a shop would charge to install the gears... but I've been told around $250-$300.

From what I understand, the FRPP gears are made by Ford and cut the same way as the stock ones, so 99% of the time you don't have to mess with the shims, which would make it 1000 times easier. (I'll let ya know for sure on that cause I am installing FRPP 4.10's myself either this coming weekend or the next)

Hope I've been of some help!

gefracing.com 4.10 gears $139 I would buy the $80 install kit too. Why take a chance on screwing up the gears. Do it right the first time it may save you headaches in the future.

thanks 4 the help n link. should i get the speed cal or just get a tuner 2 change the speedo? i hate 2 buy the tuner unless i can change the program every time i install a new part.

what kind of speed increases will i get with 4.10 gears for a pretty much stock 99gt 5spd., like as in 0-60 or 1/4 mi.
