first like to say thanks for all the help so far,



ok here the question,

i wanting to know if a 3.55 diff would be higher or lower then a 2.47 diff?

also dose it matter that the 3.55 is going to come out of a v8 power truck with a auto tranny?

and would it work in my truck a inline 6 with a 3 speed?


thanks for the help

 

Gearing numbers are a little confusing. 3.55 is higher numerically than 2.47, but it's called a "lower" gear.

If you were to drive at a certain speed with the 2.47, with the 3.55s you would be turning more RPM at the same speed.

Or another way to explain it, the higher the gearing number, the slower the tires turn in relation to the driveshaft. A 2.47 turns faster than a 3.55, and a 3.55 faster than a 4.11.

As far as your last questions I'm not sure. I would think they're the same gears and it wouldn't matter whether it's a stick or an auto, but don't quote me on that. lol

 

3.55 is going to pull loads and trailers better than the 2.47. But the engine is going to be revving higher when you are driving down the road, and your fuel mileage will suffer a little bit with the 3.55.

2.47 is not good for towing, but is good for high speed highway driving, and for good fuel economy. The engine will be turning slower with the 2.47 going down the freeway.

 

yea they are,

reason i ask is, cause ever spring we have to turn the flywheel and put a new clutch in, cause it hard to get the truck going,

we wanting to put a (lower) ratio in it,to make it like it was from the factory,


when driveing the truck you pretty much have to slip the clutch alot to get it going.

 

3.55's will definitely help that problem.
