View Full Version : Used Truck Specs

07-17-2008, 07:37 PM
I just recently bought an '04 F-250 with the 5.4L gas. I'm very pleased with this purchase but I'm wondering about some of the specs. The primary thing I'd like to know is the gear ratio at the axle.

Is it a 4.10? Maybe the 3.73? I don't have any idea but if I ever buy another gas engine truck in the future, this would surely help in my decision. We all tow so much, gear ratio is something fairly important to consider.

Anyone know any "simple" way to find this out? Could it be so simple as counting the number of driveshaft revolutions per one rear wheel revolution?

go to www.fordtrucks.com/forums and ask. If you know the VIN #, one of the guys over there can prolly tell you!

It took all of about 15 minutes to get it through FordTrucks.com. I've been a member there for a couple of years but I guess was too lazy to post there this time.

On my door pillar, my axle listing is a C1. That means 3.73 limited slip.:)

Thanks for reminding me, J&R.:hammerhead:
