Liberty
Products, Inc. recommends that tunnel and/or heat exchanger protection be
installed in all snowmobiles when traction products are utilized. Even if your
snowmobile is equipped with factory tunnel protection we suggest that you check
for adequate clearance of traction products before you ride. Riding without
performing a clearance check can result in serious damage to your snowmobile.
Stud quantities listed are based on standard stud patterns for 121” tracks that
have 48 ribs, you will have to adjust the stud quantity for shorter or longer
tracks. (Divide track length by 2.52” then multiply by desired number of studs
per lug to determine quantity of studs required-example-136”/2.52x2=108)
