Just wondering how it affected your performance, cruising speed, fuel economy.
 
I've done it on a few trucks. Mine with 6 speed and a couple others with autos. 1st gear was much more useable and fun as well as 2nd. Customers went from 12.5 to 14.5 hwy and my own achieved 19.5 over an hour drive. GoPro'd as well for naysayers ;)
 
What was the general reason for going from the 4.10 gears to 4.56 by Dodge?

I believe the 4.10 were chosen in 04 to beat the pants off the fastest truck in the world record. After that was accomplished, 4.56 for the street driven beasts.
Kinda like Vipee cars with 3.07 gears that go 60-70 in 1st gear! Well 4.10s aren't that extreme but I think 3:73 would be perfect!

The trucks came with a trailer hitch. Between 4.11 and 4.56 gearing, 4.56 is better for towing. Could be the reason.

Final drive for the QC is about a 3.14 ratio and the RC is about a 2.05

That's quite a difference for slowing the engine down on the highway for any given road speed.

Id like a more usable 1st thats for sure.

What does the 4.11 gears usually cost? Does the speedo still work?
 
I'd be interested in a little more detail about this swap as well. I have a QC that will probably never see a trailer on it.
 
Thanks for all the input. I'm gonna try the 4:56 out at first, ( because that's what I have) but since I have no plans to race it ( Maybe try the autocross ) eventually I'll swap over to the 4:10's.

Well, they weren't rated to carry crap per the manual and although the gearing, power and rear end are there, the suspension isn't. QC especially. I have warped spring trucks often! RC not an issue yet still not rated to carry more than a JetSki/Snowmobile (for you Yanks, lol)
Now, having said that I've towed 3500lb cars with ease although the springs squatted even with tongue weight correct.
Viperhauler has been known to haul dang ole backhoes with his truck so RC will do it, but not at all what SRT designed for.
 
If you decide to lower your beast I recommend going to a RC spring pack and rear end from an 04 if possible for factory setup 4.10s. Or give or take $700 for swap in your rear from 4.56-4.10. May sell your stock setup for $150 ;)

Personally, I like the 4.56s in the QC; it helps them out for let's say the under highway speed stuff.
Like we have talked about though, a converter makes the biggest difference in that range in the QC. WAY different animal with a good 26-28 installed.
I haven't really carried anything in the back except for a floor-jack and Drag Radials.
Like you say, towing isn't really what either version of these trucks was designed for.

Have Fun.

Off topic but would i be able to tow my jeep srt8 from cali to ny without any problems?


That's a tough one to answer.
There's the possibility of:

Mechanical Breakdown(s)
Running out of fuel
Traffic Delays
Traffic Accidents
Tire Problems
Speeding Tickets
Changes in weather
Car-jacking
Lost wallets
Lost cellphones
Taking a wrong turn
Vehicle Theft
Bad food or water
Fatigue
etc...








:D

I wouldn't hesitate but would add air bags to the rear. Cheap and effective load handling. Rear sway bar helps dramatically when towing as well.
