New tow vehicle

[RVNewbie4now]

Just upgraded my tow vehicle from a new Silverado 1500 to a 2500 HD. It sits about 3" higher than the other truck. My question is what adjustments will have to be done to my Blue Ox Swaypro for the change in height?

Reality is you probably won't have to do much other than lower the hitch head on the shank.

Physics is physics. The same tongue weight is pushing down on the back of both trucks. It will take the same amount of spring bar force to counteract it.

You won't *NEED* to counteract it nearly as much on the 2500HD, but it doesn't hurt to.

The new GM trucks tend to sit high in the rear. You have the option of installing "drop" shackles which can lower the rear end about 2". I have done this on my last two trucks to allow my 5th wheel to tow level with adequate bed to camper clearance. Drop Shackles

Start out at the last hole, which will drop you 3". Being 1/2" low will not be a big deal. At least that's what I'd do.

Thanks for the help. At least I have a starting point. I believe the difference in hitch height at the receiver is about 2 1/2 inches. I have two more sets of holes in the shank which would drop it another 3". So....

Really depends on hitch height of both vehicles. Hitch height delta is likely less than the overall height increase. At least it was in my case.

If you still have access to, or know the hitch height of the old vehicle, measure the hitch height on new vehicle and that will tell you what you likely need, at least as a starting point.

In the end, you have to go through the whole setup again, so just follow the instructions for the hitch and the vehicle.

Whatever it takes to have your trailer level at its highest pointing...I prefer pointing slightly down

That the TV's front axle is re-loaded as per your glove box manual. Used to be even drop front and back, but today's TVs has many different architectures (IFS, Live Axle, and bump stops that touch 100% of the time, etc)

Most likely you will need to readjust the shank...if it has adjustment holes. Some times flipping it if it was sticking up

That is the goal....all of the adjustment recommendations are just the dials/knobs/etc to get to that goal of a level trailer, or pointing slightly down after it is dialed.
