Equalizer hitch size, how big is too big?

I purchased a 12000 lb Equal-i-zer brand for the trailer in my sig last December. I installed it according to instructions myself on my previous truck (F150) and then again on my present truck (Silveraldo 2500 HD). I have been very pleased with its performance on both vehicles, especially noticing a large difference after switching hitches on the F150. I would suggest erroring on the heavy side because the hitch can always be adjusted lighter but you cannot increase the stiffness of the bars without changing them to a higher weight. For my trailer, I was on the border between the 10000 and 12000 lb setup and so I opted for the heavier.

If you decide to install yourself, you will need to torque some of the bolts very tight including the hitch ball which requires a 1-7/8" thin wall socket. I took my hitch to a local agriculture dealer and they torqued it for me for no charge...pretty nice. Otherwise you might need to purchase tools which you might not have.

I hope this has been of some help. Good luck.

Equalizer hitches are good, atleast for me and my setup.

The dealer is recommending an Equalizer brand as that's what he carries.

Why not shop around and find the hitch you want, not the one the dealer sells?

You want bars for 13% to 15% of the TT GVWR, or a bit higher.

The heavier bars, above what is needed, will affect the ride. In extreame cases they can bend the TT tongue. Just buy the correct size and be happy.
