I have a set of box brakes on two of mine not polaris They are solid brass and I run them in anything I can get into the been on for 1 and a half and no problems You might need to email and see if they make them for polaris that is what I want to put of my Polaris when this run out The web site is www.boxbrakes.com
good Luck

 

Has anyone used the EBC rotors ?? I was told they were alot better, but I'm not sure. The rear rotor for my TB is $70, the Polaris is $20.
I wonder if the new Polaris brakes will work on older models ?
