EPI Ski-Doo Bottom Gear Wide Tooth Sprockets

EPI Ski-Doo bottom gear wide tooth sprockets are replacement lower chaincase sprockets (bottom gears) for Ski-Doo snowmobiles. The bottom gear works with the top sprocket and drive chain to carry power through the chaincase to the drive axle. These wide tooth sprockets suit owners who need to replace a worn, damaged, or hooked sprocket, or who want to change their gearing.

Key Features:

• Bottom gear (lower chaincase sprocket) design made for Ski-Doo snowmobile drivetrains
• Wide tooth profile for use with wide-pitch chaincase chain
• Available in multiple tooth counts and widths, so you can match the sprocket to your chain and gearing needs
• Replaces worn sprockets to restore smooth, consistent power transfer
• Sold under the EPI brand, a name known for snowmobile and powersports drivetrain parts

Match the sprocket width and spline count to your chain and chaincase setup. Changing the tooth count on the top or bottom sprocket changes your final gearing, which affects low-end acceleration and top speed. Replacing the bottom gear is a common maintenance and performance upgrade for Ski-Doo sleds.
