Secondary Chains (2): 66 links each
Crankshaft Sprocket: 26 teeth
Camshaft Sprockets (Exhaust Side): 36 teeth
The complete kit includes: the lower chain, 2 upper chains, the crankshaft sprocket, 2 camshaft sprockets, 3 timing chain tensioners, and 3 chain guides.

WVT Gear Specifications
The intake camshaft is controlled by a hydraulically actuated WVT gear.
