I'm not a racer, but I installed a Rogue pulley last year whan ski had 199 hours, now I have 279 hours.... I took off my belt guard yesterday and had zero rust and was very impressed with the way this thing is holding up in extreme salty conditions here in Hawaii. Just thought you guys might want to hear this.... And no, Ron is not paying me to say this! lol Mahalo tho Ron.... My kids want more shirts!
