2015 3500 Ram

We have ordered our last 3 Ram duallys (2004, 2012, 2015). All arrived in about 6 weeks. That way we get exactly what we want on the truck which always includes a 4:10 rear end.

Pulling the 12,000# Montana I sometimes forget, for a long time, to use tow/haul. I only occasionally lock out 6th gear. Aisin. Go for it.

Most of the Ram 3500 duallies I see on the lot here in Texas are 3.73 trucks. There are some 3.42 trucks (the standard axle ratio - thanks EPA and CAFE standards), but 4.10s are hard to find. I had to drive to Alabama to buy the truck in my signature that I found on an internet search. Normally I have to order them to get the 4.10s.

Probably be better off just to look for a different truck rather than change all the gearing.

Love my 4.10 rear end. Personally I would not get any less than a 3.72, but you have to understand ratios, torque, and load handling further to see my point. The 3.42 will work, but he might be towing in 5th when I tow easily in 6thOD.

Big X2 here also!

I've read were guys have received quotes from dealers and private shops for gear axle ratio changes, if memory serves me correct, the rear axle was around $2,200 and do not remember the front axle cost, that is if he has 4x4.

Search around on the Cummins forum this is where I've seen a few threads discussing axle ratio changes.

That would be full retail for both ends of a 4x4. Remember the diff only then has a one year parts warranty. I believe Dave Smith was going to do cummins12V98 2011 for 1500. Chris

Yes, $1,550.

A great deal but as I have said the truck performed great with the 3.42's towing a combined 29K Just took it easy on grades taking off. Oisin would have cured that small issue!

I have a 2015 RAM SRW with a 3.42 axle that pulls a 14k pound trailer. We pulled through Colorado up the Brekenridge pass at 11500 feet with switchbacks without any problems at all. The only thing noticeable was the engine/transmission temps increasing 10 degrees staying well below the max limit. When not towing we get great mileage. The 3.42 should be fine.
