About This Product
If you are building a high-performance motor, you need a primary chain that can handle the extra grunt. These S&S Cycle primary chains are a direct replacement for the factory units but offer a significant 11% increase in strength. This makes them the perfect companion for an S&S heavy-duty compensator ramp, ensuring your primary drive remains trouble-free even under heavy loads. This specific chain is designed to fit FXR and Touring models and replaces OEM number 40037-79. It is a rugged upgrade that provides peace of mind for riders who demand more from their Big Twin, offering the durability needed for both daily riding and aggressive performance applications.
