• DO NOT INSTALL STUDS ON A 2.0"+ TRACK.
• Studs can be installed on the inner and outer track
ro
ws. Studding the inside of the track is good for
improving traction and vehicle braking. Adding
studs to the outer rows is generally considered for
drivers who desire a high degree of traction, but
can sacrifice track durability. Studs placed on the
outer rows are more susceptible to being ripped
out of the track.
• Adding studs may require the use of longer, more
ag
gressive ski wear bars/carbides.
• A wear strip kit must be installed to protect the
tunn
el and tunnel cooler when studs are installed.
NOTE: 2012-2013 Rush 121/Switchback 136 models
with Cobra track feature additional wear strips
installed into integrated coolers. The wear strips must
be installed on any 2012-2013 Rush 121/Switchback
136 equipped with a Cobra track.
• Consult stud manufacture for more information
a
nd recommendations.
Stud templates are guides designed
to locate where to drill
the track when installing studs depending on the track
length, desired number of studs, and pattern.
The 1.25 Ripsaw track used on 2010 Rush snowmobiles
fe
ature stud location indicators molded into the outer
cover of the track. The indicators mark the manufacture-
recommended stud pattern for improved performance and
maximum track durability.
Do not install stud lengths that are not recommended in
the guidelines. Severe track and/or tunnel damage may
occur.
