No, not how I use my truck. It's normally pulling a trailer and used on weekends and vacations only. If used as a daily driver with lots of highway miles it might not be for everyone. There's a stretch of I-10 with a posted speed limit of 80...I'm turning 3,000 RPM's at that speed, not so good if you're concerned about fuel mileage. I think a final gear ratio of 4.30 is ideal for towing and highway travel, the 35's should give me that final ratio. If I decide to stay with the same tire height...no regrets at all. Hope this helps!

So based on your above statement, sounds like you're saying that IF you were to stay with 33" tires, 4.56 are geared a little too low for your truck's towing/hauling duties?

Well after sitting on the fence for a couple of years, I had to finally pull the trigger on regearing. I went up a size in tire to a 33" and I am pulling more weight now with the recent purchase of a RZR XP 4 that sits in my 7500# bumper pull toyhauler. The truck was really struggling on some of the grades out here in the west. On mountain pass outside Las Vegas I could only pull 2nd barely! At one point after goint to 1st I thought we were going to slow down to a stop, but it didn't.
I have a 2000 F250 V10 supercab 4x4 Auto with 140K on the clock. It currently has 3.73s and as I type this, I am waiting on the 4.56s to be installed. I can't Wait! The wife and I debated on putting this much $ into a gasser with 140K but in the end we decided to keep the V10 going because I truly love this truck.
I will post up results after the break in.
I was going to go with 4.88s but made the last second decision to 4.56s because although it is not a daily driver, around here 80 is cruising and wanted to be able to keep up!

Don't fear the gear!

The previous owner of our '99 F350 V10 4x4 dually had 4.56s installed, and they're about perfect for towing. We pull horse trailers mostly, so we don't go past 65 regardless, and we're taching about 2200RPM at that speed. So far empty the truck gets about 14mpg, and towing we're at 11-12.

No, we don't hot rod the truck.

Next stop, 5 Star tune and y-pipe, catback exhaust and a better intake. And open up the rear diff and see if the PO had the sense to install a limited slip in the rear, the tag says it was originally a 3.73 open axle, and I really want to have as many wheels turning at the same time as I can get next time I have to tug a big loaded trailer through the monsoon mud out here.

I keep reading posts about gears and well I'm debating between 4.30 , 4.56 and 4.88. I have my f250 with an 8" lift on 37s. With stock 3.73 it's good on freeway but feels like I'm towing when city driving and stop and go traffic

First of all thanx to all this is an old thread but a good thread for all ford v10 superduty owners looking for information on gearing and its effects on driving....i too am leaning towards this gear ratio 4:56 for an upgrade seems like a good choice for guys who want to run 33''-37'' tires for tow or play...you can go up or down a size from 35'' tires to set your rig up for towing or mudding.... and Yukon seems to be the popular choice of gears.

When my truck was ordered the only boxes they checked were for V10, 4x4 and 4.30 LS axle group. It's a stripper model that came with an am/fm radio and two speakers and when I weight it the truck came in around 5600 lbs with a 1/2 tank of fuel. It currently has 168k on the clock and I put a set of 33's and it still pulls my friend's heavy trailer and my portly jeep just fine. If I was going to set up to 35's or 37's I'd defiantly get some 4.56's or 4.88's
