- Billet crankshaft sprocket with nine keyways for +/- 8 degrees of adjustability
- Billet steel crankshaft and camshaft sprockets, both heat treated for durability
- True roller chain with a 0.250 in roller diameter for reduced friction
- Captured needle camshaft sprocket thrust bearing to minimize block thrust surface friction
- Three-piece set hand-matched for the correct center distance and minimal runout

A worn engine timing set can show up as a rattle from the front of the engine, rough running or a timing-related warning light, though other parts can cause those signs too. Before replacing the set, find the cause: with the engine off and cool, look at the drained oil for metal flakes during an oil change, and leave the timing tests that need the engine running to a shop. Each engine takes one set, with one chain running between the crankshaft and camshaft sprockets.
