i have a 2001 dodge ram 1500 4x4 offroad it has 4.10 gears n gets 12 mpg im thankin bout swapin n a 3.55 gears cause i only run a 33in tire i will lose good pullin power but i thank i will gain mpgs

 

If your looking for a set I have front and rear and a carrier.

 

hey i could use your 410s im running 35s on 6-7 inches of lift

 

i could use your 4.10 send me a message

 

Bad choice, that will do the opposite.

Just keep your foot out of it and you'll do fine. Smaller gears with bigger tire will make your truck work harder to turn the tires and therefore consume more gas.

 

3.55s will make that heavy truck feel like a slug. You will also have to use more throttle to get up to rpm from a dead stop and to accelerate at lower speeds. You will LOSE MPGs in town.
You may however gain a MPG or two on interstate driving due to driving at a constant and higher rate of speed.

IMO, unless you basically travel on the open highway most of the time, NEVER tow/haul and can be REAL easy on the gas pedal to get up to speed then stay with the gears you have.

 

I have 3.55 gears. I'm getting 12.5-13.00. Probably wouldn't change anything.

 

If your running 35's you need a set of 4.56 or 4.88 gears.

Dang man. How about considering a taller (and as narrow as you can find) tire? You'd achiever the same thing by raising (numerically lowering) your overall gear ratio at a quarter of the price.

While doing such a thing, you'll need to realize your speedometer/odometer will lie to you. By putting a taller tire on you're going faster/further than it will indicate. Use a GPS to discover the difference and work the math out...

Its real easy to just look at gears, but your tire height plays a very significant role in the OVERALL gear ratio too. If you want lower gears for towing, put tiny tires on it as a first option. If you want to increase mileage put taller ROAD tires on it.

If you're interested in getting similar to stock overall ratio while running oversized tires, THEN consider dumping the $$ into gears.
