OP, I have Curt 17501 think it is the same as yours. When I got my 2.5 inch shank I had to file/grind off a little on the corners to get to fit in the reciever. I got the Curt because it was in stock locally no one in town had an Equalizer. I have had no problems in the time I have had it. Keep the head greased and I use Aero Kroil (WD 40 on steroids) on the L brackets to keep the surface rust down. I have my hitch cranked up a little but it is rock solid passing 18 wheelers.
