DO IT. I just had my 4.10's put in today, and wow, what a difference. It feels so **** light in comparison with the 35's. I was originally going to do 4.56's, but I figured if I ever had to go back to small tires I'd be screwed, so I opted for the 4,10's. The front and rear axles have adjustable collars on them, so it's easy as cake to regear, as there is no putting on shims, pressing bearings on, and so forth. Slap the carrier in there, and adjust the collars with a screwdriver, that simple. Anyhow, it definetly _feels_ faster, since it takes less throttle to get moving, and no trip to the dealer is neccesary to reprogram the computer for the new gears, since it seems that it uses the tone ring on the carrier for the speed signal. I was cruising down the highway at 75 thinking I was prolly doing around 60 when I fired up the gps just to find I was doing 76mph

 

What did it run you to do the front and rear?

 

cool stuff, i want to do this as well.... what and where did it cost you

 

Any pics of the install?

 

Hmm, well in 4.10's it will run ya about 1300 f/r installed. I have a few pics on my phone I'll post 'em later tonight.

 

so is there a little less power loss with the 35" tires on your "stock" truck with the 4.10's?

 

It's stock... honest

I'd average 18.5mpg hand calc'd on a 300 mile roundtrip with maybe 20 miles in San Antonio, which means lots of go pedal. With the 4.10's, WAYYYYY more power to the ground, top speed 110 @ 3,100rpm in OD, 17.5mpg handcald'd. WAY worth it, it takes less pedal to get going in the city, so I'm sure when I grow weary of the new-found pickup. Hopefully my tranny lasts longer, since it will hit OD and lockup at 43mph now, but shifts out as soon as you reach 1/2 pedal. I really suggest this mod

 

Thats whhy i got em stock! Now i just need the bigger shoes! End of summer, end of summmer! what tires do you have? are they a true 35?

 

im 90% sure he has 35x12.50x17 MT's

 

To go back to 3:73's was gonna be about $800 for me, $600 parts

I was running alot of empty highway then ........................ sure glad I didn't

 

I really want to do this too. Do you have a parts list of what is needed. There is a place online to buy discounted mopar parts. I already have a labor quote from my dealer at $600. Thanks

Just call up Randy's Ring and Pinion. You need a spacer for the front gears, front gears, minimum install kit (I have 7k on my truck, no need for new bearings). The rear all you need is the gears and minimum install kit. THERE ARE NO SHIMS.

 

I'm gunna have to throw in my 2 cents on this one. The only reason to go to 4.10s would be a tire at least 37in. or you are consistantly towing heavy. Swapping gears is for gassers, our cummins put down plenty of torque down low, especially with mods to make it pointless to swap gears with just 35's. Of course when you are the burnout video master like Rodriguez, 4.10's might help get them smoking a little quicker. Save your money for a torque convertor to get more power to wheels.

 

That's what I am going to do

 

I'm going to 37's in May. I'm going to do a full-race stage-5 dtt as soon as I get the money, as opposed to doing a tc/vb/input shaft, then repay labor to get the new parts installed. The tranny is the only thing holding me back from ~550 or so to the wheels, as it's the most expensive thing to do.
