Common questions
What is the primary function of these S&S Cycle rod bearings?
These rod bearings are designed to support the crankshaft's rotating journals within your Harley-Davidson engine. They are crucial for smooth operation, reducing friction, and maintaining the correct clearances in the bottom end.
Are these S&S Cycle rod bearings genuine OEM Harley-Davidson parts?
These are S&S Cycle manufactured rod bearings, engineered to meet or exceed OEM-grade specifications for Harley-Davidson compatibility. They are an aftermarket component known for their precision and quality.
Do I need to replace all my rod bearings, or can I replace just one?
