gear ratio in a dana 60

[danwheeler660]

i have dana 60s front and rear with 38 15.50 16 tires.I went out and jacked the truck up and for 1 complete spin of the tire my drive shaft only went around 2 1/8 turns.So what gear do you think i have.the truck is at 2500 rpms doing 65 on the high way with a 302 punched 30 over...any help would be great thanks...

4.10s or 4.56s

i put in everything you said, but for the tires i put 37.5, cuz most of the time they arent truly what the size wall says, plus wheel width, etc. input more precise numbers and there ya go

[danwheeler660]

thank you

Pull the covers, count the teeth and divide. Its the ONLY way to be sure.

[danwheeler660]

but i don"t know how to divide...LOL

I have a dana 44 and 9 inch with 4:10 gears if u wanna swap then u will know the gear ratio for sure lol

[danwheeler660]

nope i will keep my dana 60s i just going to get a big block and stick it in there to get the tires moving easier

Yeah a big block would help that beast roll a bit better

dose it have a pois in it? if it dose not you need to spin the tire two times around,

[danwheeler660]

no pois in it

[Blazin40s]

Just pull a cover and b done with it.  Only real way to tell like old school said above.  Count ring teeth and pinion teeth and divide

[danwheeler660]

what do i divide by how do i do it?

[J.C.]

if you take the ring gears number of teeth, and divide them by the number of teeth on the pinion gear, that will give you the ratio of your axle

[Blazin40s]

Yep!

Dollar store has calculators

looks like i have 456 gears.What size would you suggest i put in them to get more power.Like i said it is very slow when you punch it.I want more low end power.It is awsome in the mud and rocks in low range.But i need more power for the sand so i need to regear it intill i gat a new motor for it.Im looking for a 460 or 351 to rebuild.

[Blazin40s]

5.13s

[Flat_Black]

something is wrong if your having trouble with 4.56s and 38s. i have a mild built 360 turning 38s with little effort and i only got 4.10s

[Blazin40s]

Yeah...but he's basically got a one ton crew cab with a cap...that has a 302..........that's why its doggin out in 2hi

Step up the horsepower a little
