Good To Know

Q: How many idler wheels does my sled need? A: It depends on your skid setup, so count the idler positions before ordering. Most riders replace them in pairs or sets for even wear.

Q: Do I need special tools to install this? A: Standard hand tools and a torque wrench are typically enough for an idler wheel swap. Check your service manual for the correct bolt torque spec.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
