Alright, I've been wanting to change the diff gears on my ram for awhile now. I have a 06 quad cab 4.7L 2wd and running stock 3.55 gears. I'm almost positive i don't have a LSD. I guess my first question would be is it even worth doing on my truck? I don't do any towing. I will most likely run them just for the gain in acceleration. I am running 275/55 tires on the stock 20's. If it is worth the swap, what ratio should i go with? 3.90, 4.10, or 4.56? I've looked at moe's but i really dont know what i would need. I've never did this but i do plan on tackling the job myself. So is there anything else i need to consider. Any help would be great. thanks

 

yup, itd be a great idea. 4.56s for 33" or bigger tires, 4.10s for smaller. it will help with acceleration, towing, and despite what most think, it WILL help your MPGs

 

Nice. I was looking at some 4.56s. would this be what i need?

that would do the trick. make sure you get a set for the front if you have 4x4. and might want to invest in getting an aftermarket LSD. i mean they are gonna be in there already, itd save you on labor cost to do it at the same time.

 

I have a 2wd so i would just need the rear. I've looked into the 4.10 gears + Auburn LSD kit but its a little pricey for me at the moment. I think it was $765. I may just wait and save to get the whole deal at one time.

 

I personally would wait and save for the LSD as well.
If you put 4:56's into that baby with a peg leg......your gonna' roast one or the other tyres!
It will be bad enough with an LSD in place, never mind just a peg leg ha ha ha.
Al.

 

i say dont do gears yourself unless you have done them before they are a pain

 

I've done them before but last night i found out i no longer have my tools. I suspect someone either stole them or someone borrowed them and never returned them. I knew something was going to get in the way.

 

And your break-even point will be in ten years/100,000 miles.

 

Now that's what I call an investment.
