With the extra stress placed on the valve train as a result of using upgraded camshafts, and valve springs, improved timing chain strength becomes very important. Advanced punch manufacturing techniques used in the making of the TODA Heavy Duty Timing Chain have improved accuracy and reduced edge burrs leading to reduced friction and smoother chain operations. Areas such as a larger plate shape enabled the use of a larger diameter pin, which helps reduce chain stretching under constant high velocity revolutions by as much as 35%.
