What spline do i have?

[suzuki14258]

I have a 2004 ford ranger edge, automatic, 3.0 liter, 2wd, 4.10 gears, have the 8.8 rear axle. Can i find out what spline i have without pulling the axle shafts out? Im trying to price a locker and gears but need to know which spline i have. Any help would be appriciated.


Also i have asked this before but i think i decided to go with 4.56 gears instead of 4.88s. Reason is i got 17mpg when i first got the truck with stock tires, ran the tires off a sport track ( forgot size 28 i think?) i got 24 mpg. It was the sweet spot. Now i have 33 inch tires and im geting 16.5 to 19 at the best. Mostly 17-18 mpg. Im afraid if i get 4.88s they will be low and 4.56s will put me into the sweet spot?

28 spline

and 4.56's is all you need with just 33's

I'd go 4.88s, 3.0s aren't afraid to rev...

+1.

4.56 is good if you have a 4.0L, but the 3.0L needs more RPM to be at it's peak efficiency (2700-3000 or so). Remember the larger tires will have slightly more drag too (more rolling resistance).

Well the 33s are on the truck now and its turning 22-2300 at 65 to 70 which is WAY to low. Id like to be turning 2800 on the highway but i was afraid the 4:88s would put me like 32-3400???

4.88s would be at 2700RPM at 70MPH with 33s and an automatic...

Would 4:56 be like 24-2500 at the same speed? Just curious....

Yes, but it will be a bigger turd and likely get worse mileage.
