PISTON CLIPS
M-SERIES PART NUMBER SYSTEM
In 2001, Wiseco changed the part numbers on all individual
snowmobile piston kits. The P-Series part numbers have been
converted to the new M-Series part numbering system.
The P-Series system was based on the English, or Imperial
measuring system. The M-Series is based on the metric system.
The M-Series was implemented to ensure accuracy for today’s
high performance snowmobile motors.
This chart shows the new millimeter identification
