Studs
Failure to heed the following recommendations will result in tunnel or track damage and a voided warranty.
Track damage resulting from improperly installed or maintained studs is not covered under warranty. Use only POLARIS-approved traction products on your snowmobile. See your dealer for more information about installing studs and/or carbides.
Use of studs longer than the recommended length on snowmobiles equipped with center coolers will result in center cooler damage or damage to the tunnel.
Do not install studs on this snowmobile unless the proper stud protection kits have been installed or damage will occur.
The Matryx chassis requires a stud protection kit to be installed before installing studs or chassis damage will occur. This stud protection kit will protect against chassis damage with the following track/stud combinations.
