Product Description

S&S Cycle Heavy-Duty Primary Chain - Touring Models

Your primary chain is the critical link between your engine's power and the rear wheel—it deserves to be bulletproof. The S&S Cycle Heavy-Duty Primary Chain is engineered specifically for Touring models to handle increased torque from performance builds while delivering extended service life. Heat-treated components resist stretch and wear, ensuring smooth power transfer and reduced maintenance intervals. Whether you're running a stock motor or a high-output build, this chain provides the strength and reliability your bagger demands mile after mile.

Why Upgrade?

Factory primary chains are designed for stock power levels and can stretch prematurely under the stress of performance modifications, loaded touring, or high-mileage use. The S&S Heavy-Duty Primary Chain is built to withstand the demands of big-bore engines, aggressive camshafts, and heavy baggers fully loaded for long-distance riding. This chain delivers consistent power transfer without the noise, vibration, or premature wear associated with stretched factory chains, making it an essential upgrade for anyone serious about performance and reliability.
