Toda Heavy Duty timing chain (Honda K24 engines Accord/CRV)

The Toda Heavy Duty Timing Chain offers increased durability and resistance to stretch compared to the standard Honda timing chain.

An important component that's often overlooked when building high power K20 engines is the Timing Chain & Timing Chain Tensioner.
The additional stress placed on the factory Timing Chain Tensioner while employing high-lift camshafts can lead to Tensioner failure, and ultimtely engine damage.
TODA's K20 Heavy Duty Chain Tensioner addresses the weak point of the factory tensioner, being the compensator.

Up until now, tuning specialists have had to use the standard timing chain. Now there is a product that after reviewing the design and detailed modifying has gained improved accuracy and durability.
This is TODA Racing's Heavy Duty Timing Chain. With the extra demand of hi-performance driving even with the standard road engine and/or components such as camshafts that place extra stress on the valve train system, improved chain strength is important.

The highly precise side plates reduce friction and improve the revolution fatigue strength by increasing the area of the plates, a reduction in the burrs and the finish to each individual plate. Moreover, due to the higher precision of manufacture, the hole size and shape in the plate have enabled the use of a larger diameter pin, this also contributes to reducing the stretching of the chain under constant high velocity revolutions by as much as 35%.
