Hybrid Racing K-series Timing Chain Tensioner

Hybrid Racing K-series Timing Chain Tensioner


Despite being a fairly robust motor, k series engines have been found to have weak timing chain tensioners that fall victim to excessive wear when aftermarket cams are installed in the motor (and in some instances with stock cams). The fast ramp rate of aftermarket cams is the main cause of this. Unfortunately, without tearing the motor down after every use, it's almost impossible to detect a worn tensioner before it's too late. While installing a stiffer spring in an OEM tensioner, like other companies do, will slow down the wear of an OEM style tensioner, it will not eliminate it. The use of a stiffer spring will also cause the timing chain to stretch faster. For this reason, we designed our chain tensioner from scratch, ensuring it could take the abuse aftermarket cams cause without causing faster than normal stretching of the chain


Quick Overview
• Dual ratchet design
• Tighter tolerances than OEM Honda chain tensioner
• More durable than OEM unit, especially when using aftermarket cams and valve springs
