What size shank dodge 2500 4x4

I got a new dodge today and will need to replace the shank on my equalizers. I want to get the 2.5” but what should the drop be?

What size shank dodge 2500 4x4

My 2020 Ram 2500 Laramie 4x4 has a 2.5 inch receiver. Pretty sure all 2500 series models for the past few years have the 2.5 inch version. 3500 series may have the 3.0 inch size.

The truck came with an adapter sleeve to accommodate 2 inch shanks on ball mounts, but I ended up buying a new 2.5 inch ball mount sized shank. Mine has the 6 inch adjustable drop.

But I also have the auto leveling air suspension on the rear axle. Getting it close with a 4-6 drop is all that’s needed.

Equalizer 6 in Drop

I have the same truck as you and an equalizer hitch for towing a 30 ft Flying Cloud. I bought this product from E trailer since it works with my equalizer hitch head. Cost was about $140

We ended up using the 2" shank with the 10" rise/6" drop for my '18 RAM. You'll find that the 2-1/2" shank doesn't have enough drop for the height of the truck unless you have a lift on the trailer. Also, the standard length shanks won't allow you to open the tailgate with the trailer hitched up. We ended up buying an extender from e-Trailer to move the ball out about 3".

Know that moving the hitch point out 3" has about a 5-8% effect on stability critical speed and degrades handling performance about the same. The trade off may well be worth it but you have impacted maximum safe speed by about 4-7 mph.

The Ram 2500 4x4 has fairly compliant rear springs, mine settles 2 1/2 - 3 inches when hitched with gear in the bed. My base zero offset ball height is 24 3/4 so I use about 3 1/2 - 4 inch drop.

Perfect, we sold the FC25 and are waiting on our FC30. That gets you to tow level? I really did not want to buy a complete new hitch if I can just get a shank and I like the idea of a 2-1/2 shank. Any trouble with your tailgate opening and closing?

Depending on your planed travel speed, you may want a shank the has the ball close to the bumper, but then the tail gate will hit the jack housing. What was you speed range with the 25'? Will you keep the same speed with the 30'?

Tailgate question

My trailer is level with this setup, like Bayou Biker said, the truck will settle a little as the tongue comes down, so you set the ball up a little higher when trailer is not on it. I found I do not have to use very much WD tension to get the axle weights and sway control right.

I have the stock 285/60x20 in. tires and stock suspension. It is a 4x4 with Cummins.

The tailgate can open a little bit but not fully before it hits the trailer tongue jack. This is not a problem for me since I am tall and can reach most of what is in the bed by reaching over the side. I use the bed step if i need to get in there and root around for something before I unhitch.

Never over 65 really. The camper will sit at a permanent camp spot most of the time, but we will take some trips

There are some 2 1/2 inch 6 inch drop (as defined by the equalizer ball mount geometry) shanks that extend further out than what equalizer brands directly. The shank equalizer uses is industry standard, it is not custom in any way, so there are many brands with slightly different dimensions so if you look you can find one that will just barely allow the tailgate to clear. And since you don't rocket down the road, the 3 or so inch difference while does affect ride quality and stability you still have a good margin. Measure from the receiver pin hole center to the end of the tailgate on the new truck and I'l help you with dimensions for a shank so you are ready when you go to get the new trailer. Also measure the elevation of the top of the receiver hole to confirm the required drop.

A word about "drop". each hitch maker has different ball mount designs so the ball elevation relative to the shank adjustment holes varies. Zero drop is defined as the bottom of the ball being level with the top of the receiver hole.

My 07 cummins 2500 4x4 has a 2 inch reciever and I need a 6 inch drop for Airstream but I also have 35 inch tall tires, stock suspension.
