studs
I just like to say, no, you dont need tunnel protection.you have them and if you try and install anything over those coolers,you will have heating issues.IV,E RODE POLARIS AND WORKED ON POLARIS SLEDS FOR YEARS,AND I RAN WOODY STUDS 1175 IN A 1 INCH TRACK AND NEVER HAD ANY ISSUES.AND I RAN THE TRACK LOOSE FOR BETTER SPEED.THE 1175 RUNS ABOUT 7/16 OVER THE LUG TOO. SO HERES SOME INFO.POLARIS TRACK .92 YOU CAN RUN 1 INCH OR 1075.1 INCH TRACK,YOU CAN RUN 1075 OR 1175. NOW IF YOU HAVE A OLDER 3/4 TRACK.THEN YOU RUN 1 INCH STUD ONLY .BUT IF YOU HAD A .92 TRACK AND RAN 1 INCH STUDS ,YOUR NOT GOING TO GET A BITE HARDLY AT ALL. AGAIN YOUR FINE WITH THE TUNNEL.
