What size ball 24RKPR?

We are taking delivery on Friday (2/22/19) of our new 24RKPR. Knowing that dealers often under estimate the amount of time something will take I'd like to have as much ready as possible before I get there.

I bought an equalizer WD hitch for my rig. Can anyone tell me what size ball I need?

2" is what is on my 26RBPR which is very close to the 24RKPR so I am fairly certain the ball size is the same.

The ball size id 2 5/16". Just as important as the diameter of the ball is the weight rating for the ball. Be sure you buy a ball with a weight rating at least equal to the GVW of your trailer. Better yet, buy the strongest ball you can find. Eliminate all of the "weakest links" you can on initial purchase. It is much more expensive to buy a 7500 pound ball for your hitch so you can tow a 5000 pound trailer, then in 2 years, you decide to buy a 9000 pound trailer and your ball is under-rated.

JRTJH, thanks for the response.

We haven't met, so you are unaware of how I overbuild everything when given an option. For example, I'll be towing this 7,500 pound TT with a Diesel F350. I appreciate the coaching.

A previous reply suggested a 2" ball and referenced ownership of a slightly larger TT. What is your 2 5/16" suggestion based on?

Typically all TTs have a 2 5/16" ball, never owned one that wasn't. Utility trailers & possibly small lightweight TTs have a 2".

Congratulations!
Unless you have a very old trailer I would bet you need a 2 5/16" ball.

My 2018 keystone bullet 261RBSWE has a 2-5/16" hitch. My buddies 1971 Ideal uses a 2" ball. In order to use my WD hitch pulling his rig hunting I had to find a 1-1/4 shank 2" ball, and borrow a 3/4 Dr ratchet and socket to swap them. I think all or most modern rigs will have a 2-5/6 coupler.

2 5/16" ball is what you will need.

Since the equalizer doesn't come with the ball, as you look for the 2 5/16" ball make sure it is the LARGE SHANK. small shank collar comes with the hitch IIRC but We don't use them. another thing, the ball is a PITA to install as it takes a 1 7/8" socket and it can get caught up on the bar slots.

The equalizer manual specifies a 1 1/4" shank and no longer than 2 3/8".

I ordered the equalizer ball 2 5/16' rated at 14,000 pounds. Thanks for all the input.

I'll third the 2-5/16 ball. That's what our 272UFL Outback came standard with.

If you're going to install the Equalizer yourself, or maintain it actually, realize you will need a heavy duty torque wrench that can handle 400 ft.lb. or so. I also had to go to NAPA and buy a thin wall socket for the ball nut because a regular socket was too thick to get into the recess.

430 foot pounds according to the manual. That's the 4 foot long or so variety of torque wrench. Luckily I can check out tools from work, use at home, and then take them back. If I'm really lucky I'll score one that fails calibration and get to keep it on a scrap pass. Our calibration standards are very high at work.

I use an air impact gun from HF, it’s rated at 600+ ft/lbs. it does better than my buddies Mac. I do use HIS socket from Tractor Supply.

How do you know you are at specific torque value? I looked at the manuals for all of the current 3/4" drive models and there wasn't an adjustment. I'm always looking for an excuse to buy a tool.

I'm OK with using an impact driver to remove tight/stuck nuts. But when it comes to installing to a specified torque is there a way to do that with a HF air tool?

We use hand torque wrenches at work, and Hytorc for the big stuff and special circumstances. Hytorc is way out of the RVers budget.

These guys have got to right. I am 500 miles from my trailer when I answered and didn't look but John and Danny KNOW.

Sorry for the confusion
