Cloyes 9-3658TX3 timing set for the 1999-2007 Chevrolet Silverado 1500 V8 4.8L or 5.3L, the 2003-2007 Silverado 1500 V8 6.0L and other vehicles links the crankshaft to the camshaft so the valves open in step with the pistons. The performance set, which some shoppers call an engine timing set, uses a single roller chain.
- Billet crankshaft sprocket with three keyways for +/- 4 degrees of adjustability
- Both billet steel sprockets are 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
Quick facts
- Part: Cloyes 9-3658TX3 timing set
- Also called: engine timing set

Timing chain wear can show up as a rattle at startup, rough running or a check engine light, and sensor or ignition faults produce some of the same symptoms. Before you replace the timing set, rule out those causes, such as a failing crankshaft or camshaft position sensor. Each engine takes one set, with one sprocket on the crankshaft and one on the camshaft.

Does this timing set include a camshaft thrust bearing?
Yes. This set includes a captured needle camshaft sprocket thrust bearing, which minimizes block thrust surface friction, along with the crankshaft sprocket, camshaft sprocket and chain.
How far can the crankshaft sprocket on the Cloyes 9-3658TX3 be adjusted?
The billet crankshaft sprocket has three keyways, which give +/- 4 degrees of adjustability for the Cloyes 9-3658TX3.
What roller diameter does the chain in this timing set have?
The single roller chain is a true roller design with a 0.250 in roller diameter, intended to reduce friction.
Are the sprockets in this timing set heat treated?
Yes. Both sprockets are billet steel and heat treated for durability, and the three pieces are hand-matched to set the correct center distance and limit runout.
