Question Cost of changing my axle ratio

I have a 1999 F350 that has 4:10 and I would like to change to 3:73 or possibly 3:55. Any idea on cost for the parts required?
Thanks,
Craig

I don't want to change any tires or wheels. Just the gearing. It is a diesel that I won't be pulling anything that is real heavy. I would like to go to 3:73 or 3:55 for mileage purposes. What do you think? Cost??

The price that Abendx gave is mostly on key.
If you do a lot of highway driving, the 3:73's will give you a little more mpg.
3:73 are a stock offered gear will be cheaper and more obtainable that 3:55's

My opinion, not worth the money to go from 4:10 to 3:73's

I'm sure there are some folks out there running larger tires that would love to trade a 3.73 for a 4.10. Maybe you could hook up with someone on this board and trade gears. It would at least save the cost of the parts.

Are these costs for 2WD's??? I assume 4WD requies a front change as well??? How much extra?

no... these prices are for two axels.....

about 300 in labor per axel and 300 per axel in materials (ring and pinion and install kit). another 150 or so if you need your carrier replaced (which i don't believe he will with a change from 4.10 to 3.73).

some things to consider.... you will lose A LOT of power when you do this and towing will be harder on the engine.

also, i'd not go the route of swaping gears with anyone.... gears break in and if swapped you might have lots of problems. best to put out the cash and go new!

At the rist of sounding like an idiot I will update everyone (which by the way, thank you for your responses and input). The pickup is one that I am buying. The owner "thought" he had 4:10 but after I asked him to verify, he has discovered that it has 3:73's which is what I want. I apologize for wasting everyone's time.

I have a shop in Texas and my truck needs 4:10 gears. It currently has 3:73s in very good condition. Are you interested in an even swap I pay shipping both ways.
