Wheel mass is also a factor. The HD wheels are heavy.

So y'all, how much of a difference would there be between 4.10's and 4.30's?

 

4.30s, it's a truck gas mileage goes so far. May as well make her fast

 

about 200 rpms

 

200 rpm, my decision is made.

 

actually, according to that chart, its only around 100 rpms

 

Duh. All I had to do was read the chart I posted.

 

yeah, pretty much

 

 

My friend and coworker and fishing buddy who has a jeep with 4.10's and 33" tires says I should just keep the 3.55's. I think 4.30 gears would make for a more spirited truck and provide the best towing. Plus if I ever can afford a supercharger...

 

if you dont travel over 60mph much, then get the 4.30 gears. otherwise, go with 4.10's.


you should turn right around 2k rpms at 60 with the 4.30's and 31" tires.

 

That's not bad. I sometimes get to 65 but the highways here are mostly 60. My speeding days are long gone. lol

 

yeah, its not too bad, i can still get almost 14mpg when im driving on the highway.

but you will really like the extra pep, thats for sure!!

 

I bet! I can't spin the tires right now. I think that'll change. lol

 

thats because its so hot out..... Oh and you should have gotten a 4.6 both my trucks can break em loose

 

I've never been able to spin em in my truck.
