axle code R5

in my ranger which is a 3.55:1 gear set according the the tech library on this site.

whats weird is it has the factory installed tow package with auto tranny... dare i say if i put some 3.73's or 4.10's it would haul even more ass? worse gas mileage? it cruses at 2200 rpms at 65

Up to about 2500 RPM cruising I don't see much impact on your mileage.

What size are the tires you're running?

 

[DFracing]

29.5 but getting 31's here soon i runnin on slicks.

or i might do a 3 inch and some 33's

 

[4x4junkie]

I'd go to at least 4.10s, or even 4.56 if you're planning on 33s.

with 4.56s and 33s what rpm will that put me at cruising on the freeway

 

[4x4junkie]

With the auto tranny (TC locked), probably around 2260 RPM @ 65 MPH. You could even do 4.88 gears too, which would put you a little over 2400.

with 4.56s and 33s what rpm will that put me at cruising on the freeway

4.0/a4ld/4.56's/33's is PERFECT for my b2, IMO.
i'm glad i didn't decide on 4.10's.

ive got the 5r55e i know its basically the same tranny but not sure what the final drive is
so im thinking 4.56s i might do 410si think the 4.0 has the power to pull them

Personally, I'm glad I was talked into 4.56's
My truck gets used around town and trails. Very few interstate miles... If you drive a lot of interstate you may want 4.10's but I don't think you'll like it around town. Stop and go is what killed me when I ha 3.73's and 33's but now, it doesn't bother me.

i drive 30 miles a day freeway so i need to keep my rpms down a little. but at the same time i do more driving around town on the weekend than my commute to work. i drive up to 250 from friday night to sunday.

With the auto tranny (TC locked), probably around 2260 RPM @ 65 MPH. You could even do 4.88 gears too, which would put you a little over 2400.

i cant even imagine how fast my drive shaft would be spinning with that combo kinda freeky to think about lol

 

[4x4junkie]

I have 5.13s and 35s... Never had any issues in the 35,000 or so miles I've put on it.

All RBV automatics have the same 0.75:1 OD ratio. Sounds to me like 4.56 is the one to go with in your case.

I had 3.45 with stock size tires. Went to 4.10 and 31" Works perfect for me, the speedo is off by 6% according to my gps. 100kph speedo=94kph gps. Helps in avoiding speeding tickets.
