im looking into the 4.56 gears hard but i dont know to much on what i all need i have a: 2wd 04 dodge ram reg cab 1500 with the 4.7 and have the 3.55 gears in it now. So what do i all need to get going with the 4.56 gears? any help is needed thanks Dusty.

 

The gears (200.00), an installation kit (35.00), and someone that knows how to do it for free (Pricless!!!) and can reset the cpu for the new gears!

There is something else that Dodge reccomends you change out, but i can't remember what it is.

 

call Jeremy at www.ringpinion.biz

You will need a master install kit for about $100 and then the gears for $150-$200ish depending on what you want. Labor should NOT be over $300 per axle I had a guy quote $250 and axle but he was too far away.

well i will put them in my self, my boss said we would be able to do it while im at work some time so ill be getting paid to do it :-D

 

Or you could jump to 4.10gears. You would see a pretty big difference going from 3.55's to 4.10's but if you really want to go with 4.56gears thats up to you.

 

So what is the reason to go to the 4:56 gears ?? Is it for better MPG or Performance or both??

 

Well you will get better performance and some have seen an increase in mpg.

 

...for me it was performance...my truck doesn't feel heavy at all and moves amazingly quick...also...on the high end (110 mph+) I don't have to have my foot buried into the floor...
