Towed a f350 dually home from Miami last weekend with my 1/2 ton 90 300 5 speed...70mph on highway no problem.(Till I needed to stop!) lol

truck in progress

a higher gear ratio would do the oppositte it would actually slow you down even more. on my old dodge i had 4.10 and with it floored my 318 couldnt get past 80 unless it was downhill

It'll take the top end down but help the acceleration. I need acceleration help. I'll take the hit on the 90mph top end to get it moving faster

So how exactly do you know what gears you have?

mustangGT90210

Door jamb sticker. 18 and H8 are 3.08 and 3.08LS, 19 and H9 are 3.55 and 3.55LS. Those are just the codes I know. You can also crawl under your truck and there's a tag on the diff cover. It'll have on there somewhere on the tag a part that says 3 55 or 3L55 (the L is for limited slip)

I just use 3.55 as an example

or get a f250 with the 460 10-14 mpg and it will pull your mustang up any mountain on its roof

f250
35 = 4.10 ratio open axle
C5 = 4.10 ratio limited slip

39 = 3.55 ratio open axle
C9 = 3.55 ratio limited slip

I have 3.08 gears. Good? Or bad?

mustangGT90210

IF you stay on stock tires they should be alright to pull with. If you're on 31s or larger they aren't too good. I've ot 31s and 3.08s but she'll still pull pretty well

jwh0818

Okay well I'm looking to pull a 10×5 flatbed trailer with 2 tons on it. Can I do it?
