Where to find Ford 3.90 gears for an 8.8.
I've looked everywhere...and can not find them. about six months ago they were everywhere. What happened?

thanks

Ford never made a 3.90 ratio. Richmond and Motive sell 3.90s though.

really? are you absolutely positive? i could have swore that GEFracing.com offered FMS 3.90 gears about 5 months ago.
i've always been told not to use any gears besides ford so i guess i will just have to settle for 3.73s then?
this is probably all over the forum but was is the rpm with 4.10s goin 70 in 5th?

thanks
anyone else with input please

FMS 3.90 doesnt exist, sorry dude

oh well, guess i'll just go with the 4.10s then.
Speed545...I'm assuming you like your 4.10s? is first gear almost useless?

Dude i have 4.10 gears and no 1st gear is not useless.. who the hell started that anyway..

actually a 3.90 gear is a 9 inch rear gear ratio .

Just go to partshopper. Pro 5.0 makes them. Im very happy with mine.
