You are bidding on a brand new upgrade for a Yamaha Banshee 87-2006. This is a pancake bearing that eliminates a common problem on Banshees where the clutch rod welds to the ball. That can cause catastrophic problems for your engine, but this is an inexpensive fix.
All newer ATVs have the push rod bearings installed from the factory to prevent this failure. Also included in this ad is a billet water pump to help improve coolant flow and prevent cooling system failures. Impeller is Billet aluminum with a stainless shaft.
