Hayden Enterprises

Hayden is known for specializing in high-quality performance parts, primarily focused on primary drive systems and tensioners for Harley-Davidson motorcycles. Their products are known to be innovative solutions that enhance the performance, reliability, and durability of Harley engines and primary systems.

The M6 Primary Chain Tensioner is Hayden's flagship product, designed to provide constant tension to the primary chain, which connects the engine to the transmission. The stock chain tensioner on many Harley models tends to allow too much slack, especially as the engine heats up, leading to vibration, excessive wear, and even potential damage to the transmission or engine.

These Tensioners reduce vibration, increase longevity and improve power transfer. They are available for several Harley models including Baggers, M8 Softails, Dynas and Sportsters.
