Scott Rasmussen –
Cap works fine but the threads are cheap plastic and even though I replaced the master cylinder, the threads are in the frame of the receiver and they just shredded as soon as I tried to screw it in. I just use it as a push on cap now. Kinda sucks.
David C. –
Be careful – it strips easily.
Andy –
Cap fits perfect on my old hitch. Old one stripped out and this one seems like it won’t strip quite as easily.
J. Kennedy –
It’s a MC cap. It works better than the 10+ year old cap I had. Not much more to ask for, in a cap!
Justin Hill –
Kind of expensive for what it is, but if you’re replacing the rest of the brake system or you lose your cap this is your go to. I was the former so I replaced the cap while I was doing the rest and kept the old one just in case something happened to this new one. Fits as expected and does what I needed it to
