No reason for bigger tires when towing is in mind. Looks like that is about what Ian's tires are too. I've had a couple inch taller tires before and didn't notice much. IIRC about 100 rpm difference at 75. 3.73's will give you about 200 rpm over 3.55's, 4.10's are +-600.
3.55's mean higher EGT's cause of higher engine lugging while accelerating also.
Just a thought.
false, i swapped over to 3:55s from my turd 4:10s and its litterally the best thing ive done to this truck, drivability, power, acceleration has never been better. ive noticed zero egt difference BESIDES when im really cooking up top because theres more gear. the gearing with a zf5 and 3:55s i believe is a very potent combo! 4;10s and a zf5 you just run out of gear because theres no power in a 7.3 up top but with 3:55s theres just an incredible amount of more usable power. these 2s really shine now, cant wait to see how the turbo does!
haha, i love my 4.11's on my truck but i do have an automatic..i wanna do a 351 swap and go to a ZF-5 and change to manual 4x4 shifter instead of this BS push button 4x4.
I have plenty of power Ian with my setup and its just about what you'll have when done except auto to 5spd. No problem with egts accelerating, and you see what I pull. I used to want 4.10's, before I did my upgrades, but now no way. I wouldn't mind 3.73's, but 4.10 is too low, don't need it. If you do a switch, give 3.73's a big thought.
Oh yeah, nice truck ****!
Yea, I really think I would be happier with 3.73s...
