Both my '06 Single wheel G56 and '17 Dually 68RFE were 3.73 gears.
She was pulled with no problems at all.
I am looking at a '15 single wheel with 3.42 gears and 68RFE.
I am not sure why someone would want 3.42in a 3500 anyway.
So the question for those with experience with 3.42 is how does it pull?
I'm not a daily puller, but I have a 5th wheel camper and a gooseneck for my tractor and whatever else.
Thanks for the responses!

I have those gears in my 2016 3500 G56 35x12.50 tires and never had any issues.
I bought the truck new.

Before regear, you think it's okay.
After regear, you wonder why you waited so long to change it.
If you do a ton of unloaded highway miles, don't regear it.
If it lives, it's a life-loaded heavy or towing regear.

My dually has 3.73 gears.
The advantage is increased towing capacity and easier transmission when moving from a stop.
The disadvantage is slightly less MPG at highway speeds.
The 3.42 gears will be harder on your transmission especially when towing heavy.

Having towed with both 4:10 and 3:42’s on the same trailers, as long as you understand that it will be slower to take off from a dead stop, especially on hills, you can do it.
However, if towing most of the time, go for 3:73 or 4:10. I have never regretted returning to 4:10 gears.

2016 G56 runs 2000 rpm at 73-74 mph.
She tows amazingly at 70.
I've towed plenty of heavy, and the OEM setup handled 30k combined well.
I would hold speed even on Saluda grade (6%) and I 40 through Tennesee.
Even more so once deleting and tuning.

Like others, about 3.42 is okay; I think they need to regulate the throttle.
The engine is more than willing to treat the transmission as a consumable, but I accept running with the slow trucks.

Thanks for everyone’s response!
Thinking I’m a little scared of the extra strain on the tranny starting and pulling the hills with the 3.42s.
Just not sure!
Thanks.

Stay out of 5-6 gear when towing; you probably won't see much issue.Originally Posted by fourteen
Tow in OD, and you'll burn it up regardless of gearing.

Imo 3.42s suck with the auto trans and it's worth it to swap them out. The G56 has lower internal gearing and it's fine with 3.42s. I swapped mine out for 4.10s and love them.
