I own a 2007 Mega Cab 1500 Hemi with the 3.73 rear end. I have thought about upgrading to a 4.10 rear end to tow more. Is there anyone out there that has done the same.
Thanks

 

yup you wont be disapointed in the 4:10 at all
i had a 2004 ram 1500 single cab with 3:73's upgraded to 4:56's liked it
now in my megacab it was speacial ordered with 4:10's reallllly love them allot more than the 4:56's . now thats 2 different trucks and weights but having ssaid that for $hits and grins i drove a megacab with 3:73's and it was a dogg compaired to my mega with the 4:10's

 

Well I'd say if your in the diffs then go for 4.56's its only about another
200~ or so rpm increase on the highway from 4.10's but if you plan on
towing or adding bigger tires then the big gears are the way to go.

 

4:10 has just as much power as the 4:56 and in the 4:10 you will get a touch better mpg's.

 

Didn't your 1500 have taller tires? That would make up the difference in the two.

 

After researching the difference in the towing capacity I am not sure if is worthe the money going to the 4.10. Can the Mega Cab 1500 Hemi 4x4 pull 10k Ibs? I know Chrysler has the truck rated at a weak 7,300 Ibs.

 

Power from a set of gears? I'd really like to see a dyno that shows how gears add power...

Gears don't add any power, they simply give you a mathematical advantage and take a LOT of work off the transmission and put it on the engine, which is much better designed to handle it.

If ordering from the factory on a new truck, I'd opt for the 4.10s in a heartbeat. If purchasing aftermarket, I'd step right on up to 4.56s on a vehicle that was going to see larger tires and/or towing use.

200 more RPMs at speed will make such a small mpg difference you probably would barely be able to measure it, but that little bit of extra rpm will significantly help you get a load moving without as much pressure on the throttle.

IMO, if you're going to go to the expense of a gear swap, go straight to the 4.56s...


I have read in a Dodge truck towing guide, published in about 2005 that going from 3.92 gears in a 1500 to 4.56 effectively increases towing capacity by 1000 lbs. Also I read a link on another forum that pointed to some camper association page that basically stated the same thing. I'll try to find the site, but it was a few years ago that I read it.

 

Good info Hammer thanks

 

where can you get the gears to do this? I have a 06 ram 2500 and it has 3:73's now and I would like to go up to 4:56.
