Fox T-Bird/Cougar Forums  

a friend of mine gave me the gears out of a '91 ranger that had the 7.5 with 4.10 gears...wondering if his bronco 4cyl 4x4 would have lower gears...4.10 is a lil extreme I think...she'd launch like heck *boom goes the 7.5* then probably have no top end?

Got 3.73 gears and a traction lock in my 5.0 Bird. Seems to have enough giddy up. I think with 4.10s even with overdrive on the higway you'll be turning a rediculous rpms. My Bird with 3.73 gears turns about 2300-2400 at about 60 mph in OD. With 4.10s you'de probibly be turning over 2500 rpms in OD and have horrible gas mileage. And yeas by going with lower (numerically higher) gears you will loose top speed. But who goes 120 mph on the freeway anyways (I'm taliking to all you sane people  ).

I have 3.73's in my daily driver 88 bird  that i wish were 4.10's
the car actually picked up gas milage with the gear swap and i have no fear breaking the 7.5 even with what few things is done to mine :D

also are ranger rear end caps stronger than the t-bird 7.5?

have any numerically lower gears...higher than 2.73s? might make trade...I'd like no higher than 3.55s...also are ranger rear end caps stronger than the t-bird 7.5?

2,500 @ 75 mph here in od  and get 26-28 mpg doing it

Next time I've got the Bird out I'll take it on the expressway and drive 70 in 3rd. Then I'll officaly pass into man hood  . J/k TurboCoupe50  .
