3.55 gears, like or disslike?

[FireFighter12]

Ive got a 1997 f250 ext. cab 4x4 with the 4.10 rear in it. I do not haul heavy loads. The occational trip to the boat ramp with the bout is about it. Im concidering swaping out the gears for some 3.55. One being im hoping to get better mpg, the second being less stress on the motor while cruising on the interstate. Just wanted to hear some feedback from those who currently are running the 3.55 setup.

IF you don't tow heavy, They are nice. I tow a 7500 lb, 5er and can tow @ 70 mph all day and only turn about 2000 rpms

Don't forget, it's also got a 4.10 front end...I love my 3.55's

id be switching to the 3.55s.... i love mine... i run 315/75/16s and i can run 100 km/h with my RPM's under 1500.... my truck is super easy on fuel, hauling a 2 horse bumper pull trailer with 2 2200lb horses in it and i still have all kinds of power.... and im all stock. i can easily pass people with the trailer on and horses without dropping a gear, i'd never run 4:10s unless i was sled pulling

Yea it looks like im going to plan on making that swap in the near future. The 4.10's are just more than i need. Like i said i basically use the truck as my daily driver to and from work, maybe a bass tournament on the weekend if there is time. You mentioned you are running 315's on ur truck. Is your truck lifted? Ive seen threads on here were people say that have 315's on a stock f250

ive got 3.55's and the mileage is nice,although it does feel underpowered in od when towing.Sometimes i find myself wishing i had 4.10s and an automatic trans......I dont understand why everyone wants to swap to a manual,i think an auto would be more powerful and better to drive.I guess the grass is always greener on the other side of the fence.>>>>>brian

i've got 3.55's and 35's with the zf5, and I love my combo. wow, lots of 5's in my truck

nice looking truck Tbone. Im not looking to switch to a manual just really concidering switching out the rear to the 3.55. Just want to get the most out of this truck performance wise, but want to be efficient as well. The 4.10's seem to be fine for driving around town or anything under 55mph, anything above that and its really reving out. Perhaps some bigger tires would help as well. But i really think the answer is the 3.55s

yah i have a 3 inch body lift, which is perfect for what i use the truck for (work truck) ive had other trucks with suspensions lifts , and they were not half the truck this one is working it( hauling hay/ lobster traps/ grain / trailers)
