Stock Gear Ratio?

Guys,

Getting ready to order a tune from Jody at DP-Tuner soon. It seems he needs the PCM code, and the rear end gear ratio. Planning to pull the PCM to check the code on it, but I was wondering if there was any way to know what my stock gear ratio was without crawling under the truck to look at the tag?

It's a stock 2000, Powerstroke, Auto, SRW, 4x4, XLT.

Thanks in advance.

I think you can tell from the axle code on the door jam... post it and someone will tell you. Or if I can find the link to the decoding chart I'll post it.

The only axle ratio available on the '00 diesel SRW was 3.73.

Casey is correct. 4.10 was possible, but only with DRW I believe.

Robert,
Crawl up under that truck and get the numbers off the tag. No margin for error. It's on the tag thats fastened to the diff cover.
Not hard to find...Peace of mind.

Your PCM code should be on a piece of sticky paper. It is located by the hinges on the front driver's side door.
