2015 Ram 1500 towing?
Hello all, Well, here I am again, at the end of a truck lease cycle. I've been leasing trucks every 2 or 3 years for the last 20+ years...it works for me. My current truck is a 2013 Ram 1500 B...

I guess I could have been more clear. I do have multiple issues and I am trying to attack all of them on all fronts. The handling I am hoping is due to the tires, which we will see this weekend, and I am going to play around with the 4 point to see if I need to make some adjustments.
As for the gears, this was mainly to help me out with the inclines. California topography is very diverse. you cannot go 100 miles without hitting some major grades. This was an issue I noticed as many large toyhaulers were smoking me on the grades. And reading throught this forum, everyone seems real happy with their Ram 1500's using the 3.92 gears, while I am way down at 3.21. Not that I want to just piss away money, I just want to get my truck in as prime of towing condition as possible, so I can deal with it for another 3 years or so until i can upgrade.
So you're only having problems with highway speed grades? If so, a gear swap will NOT help. Here's why:
A while back I did the calculations on Ramforumz, and because the 8 spd ZF's ratios are so tight, the difference in RPM between a 3.21 truck and 3.92 truck is exactly 1 gear apart!
Meaning, if you're at 4500 rpm in 5th gear, you'll be at almost exactly 4500 in 6th gear on a 3.92 truck. If you get 3.92 gears, you'll be at the exact same RPM (and therefore pulling power), but only 1 gear higher. Or backwards, if you dropped 1 gear lower, you'll be the same as a 3.92 truck.
The only time a 3.92 truck has an advantage is starting off on an extremely steep hill, we're talking 10,000 lbs trailer on 20+%.
If you're interested in the exact numbers I'll try to find my old post.
