Polaris MATRIX INDY VR1 Series Owner's Manual page 123

Failure to heed the following recommendations will result in tunnel or track
• 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.
• Aggressive studding patterns may require grinding protruding stud bolts
flush to prevent idler wheel damage. Maintain track tension on studded
tracks on the tight side of the specification to prevent heat exchanger
damage. The center of the stud must be at least 1 1/8 inch (2.9 cm) from any
edge of the track, including track window.
• Studding the outside band of the track diminishes durability.
• Polaris does not recommend studs on the outside band of the Storm 150
track. 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.
CHASSIS/TRACK
Matryx 129 / Storm 150
