About This Product
The inner cam chain, also known as the secondary chain, is what keeps your camshafts in perfect sync. On early 1999 to 2006 Twin Cam engines, excluding the 2006 Dyna, this chain is a vital component of the timing system. Over time, these chains can stretch or show wear, leading to timing inaccuracies or excessive noise in the cam chest. This MCS replacement is a reliable alternative to the factory part, referencing OEM 25607-99. Whether you are performing a standard service or a full cam upgrade, replacing the inner chain ensures your valve train remains reliable for miles to come. It is built to meet original equipment specifications for a perfect fit.
Manufacturer part number: 921161.
