Product Description

S&S Cycle Heavy-Duty Inner Cam Chain - 2007-2018 Twin Cam

Precision timing is everything in your Twin Cam engine, and the inner cam chain plays a critical role in maintaining accurate valve train operation. The S&S Cycle Heavy-Duty Inner Cam Chain is engineered to handle the increased stress of performance builds while delivering extended service life compared to factory chains. Heat-treated construction resists stretch and wear, ensuring consistent cam timing under load. Whether you're building a high-performance motor or replacing a worn chain during routine maintenance, this upgrade provides the durability and reliability your Twin Cam engine demands.

Why Upgrade?

Stock inner cam chains on Twin Cam engines are designed for mild factory power levels and can stretch prematurely when subjected to performance camshafts, high-compression builds, or sustained high-RPM operation. The S&S Heavy-Duty Inner Cam Chain is built to withstand the demands of modified engines, delivering the strength needed for aggressive cam profiles and performance valve springs. This chain maintains precise timing throughout the RPM range, eliminating the timing drift and noise that can develop with stretched factory chains.

Note: Part Number 330-0819. Designed for 2007-2017 Twin Cam engines (not compatible with Milwaukee-Eight). Professional installation recommended for proper timing setup and tensioner adjustment. Replace both inner and outer cam chains together for best results.
