Toyota 13506-22010 Timing Chain Kit

The 13506-22010 timing chain kit is engineered for Toyota K-series overhead camshaft engines. The kit comprises a duplex (double-row) roller chain with 56 links, manufactured from heat-treated alloy steel for wear resistance and tensile strength. Included components are the timing chain, chain guides (slipper and tensioner side), and a hydraulic tensioner assembly designed to maintain optimal chain tension across engine speed and load ranges. This kit addresses chain stretch, guide wear, and tensioner failure common in high-mileage applications.
