3.55's to 4.56's

[jstacey8]

Looking to start buying parts for this swap but before I do so how much of a improvement will it be? I'm on 37's and I know from the gearing caculater that 33's and 3.55's is the same final ratio as 4.56's and 37's so will it pull the same as it did stock or close to it?

Actually the 37s would need about a 3.98 gear ratio to be the same as the 33s and 3.55s. I would say it would be a improvement no doubt to get the 4.56s no matter what

Before dumping all that money in gears, I'd make sure that's the truck you wanna keep for awhile.

It's not the truck I want for ever. I want a white or silver of some shade cummins but I don't want that payment quite yet and I'm just getting into tileing and want to see how it goes for a bit before I jump into things because I'd like my house to be built by the time I'm 25 (I'm a carpenter also) so I'm gunna keep this for atleast a few more years and figure gears aren't much more then a tranny so I might as well do them and enjoy the fun

It will improve your acceleration compared to what you have right now.

If you have a. 2x4 it's money well spent. Huge difference.

Just know when you trade it in the dealer isn't gonna give 2 ***** that you have all this money in it. I wanted a cummins so I went ahead and got it before I kept dumping money in my 1500.

Is it bad that I want both?

That's assuming he would trade. He could private party and make some some money on the extras. A truck is worth what someone is willing to pay for it.

Yeah, I'm not willing to waste time showing it to 45 people so 44 of them can be all " man my credit score is a 511, why can't I get a loan"

When it goes it will be private sale. I have several people around town begging me to sell it but that's a little ways down the road

Here's is what I paid in the SoCal area and the options he gave me. I tow and have 35s I'm running 4.56s I can't tell that I'm towing now. Worth every penny

It will be a hell of a diff !
I had a 79 Toyota 4x4 with a Buick 231V6 & 350 turbo xsmn with .411 gears with 44" X 18.5" super swampers it ran okay not a slug but okay , I put .531 gears front and back and WOW what a difference! I could bust a 2nd with 44" tires !
You will love the .456s

ill throw this question in this thread so i dont need to make a new one. I know its suggested that you get new cv shafts with the older diff but do i really need to?

Im going to pick up a 2010 diff soon from PA and i just dont want to spend another 100-150 on cv shafts if i can re use my current shafts.

Whats the difference between the 07?-11 shafts vs 12-16? If there was a real difference wouldn't i need to replace the wheel hubs to older ones also?

Sounds like diameter and number of splines. If the aren't the same they aren't compatible. They would have to match perfectly or no-go.
