If you ever tow more than a rowboat, then go for the 4.30 gear ratio.

4.23 will account for only the increased diameter of the tires. You'll also need a bit shorter than 4.23 because of increased drag from a bigger tire patch, and increased aero drag from the lift and bigger tires. So 4.30 should get you close to stock performance considering all the factors.

If you never tow more than a rowboat, then I'd wait and see how you like the longer legs of the 3.73 gears with the tall tires. You can always change the gears out later down the road.

Aftermarket.

An F-250 or F-350 SRW is going to have a stock 3.73 axle ratio. Period. So if you customize the truck you might want to change the stock axle ratio. The Ford dealer can probably do it, but normally you'd use an aftermarket specialist to change the ring gear and pinion.

I'm in the process of checking costs through both Ford and aftermarket. Aftermarket should be cheaper, but we'll see.

Plan ahead.

Randy's Ring and Pinion is an excellent source for the parts. But right now both the 4.30 rear and the 4.30 front rings and pinions are out of stock.

Don't order the parts unless you plan to DIY. Most diff experts won't do the job unless they sell you the parts, too. And most of those guys will charge you a lot more than Randy's price for the parts. [img]/ubbthreads/images/graemlins/shrug.gif[/img]

I've seen gear changes done on old cars, like Chevelles, but never on a newer vehicle. Is the process any easier than it used to be? I'm not sure I'm comfortable messing with them.

Ford quoted approx. $2500.
