Timing Cam Sprocket Buying Guide — Cheap OEM Replacement Parts for Sale | REVXSC
Looking for cheap timing cam sprockets that won't fail in 6 months? Whether you're chasing ford 5.0 timing chain and sprocket kit, how to replace a cam sprocket, timing chain rattle on startup, double roller vs stock timing set, cam sprocket replacement cost, this guide covers what to buy, what to skip, and how to make sure the part you order actually fits your truck or car. Every timing cam sprocket sold at REVXSC ships with a verified year/make/model/engine fitment table — no guessing.
What timing cam sprockets actually do
In one sentence: the toothed gear at the front of the camshaft that meshes with the timing chain or belt to keep valve timing in sync with the crankshaft. When they wear out, you'll typically feel it before you see it — your car starts telling you something is wrong, and ignoring it gets expensive.
Signs you need new timing cam sprockets
- timing chain rattle from the front cover at startup
- engine running rough or misfiring with timing-related codes
- loss of power and bad fuel economy
- metal in the oil from sprocket wear
- engine that jumps timing or won't start after sitting
If you tick more than one box, replace before it leaves you on the side of the road. The repair gets a lot cheaper when you catch it early.
Also known as

Common questions Americans ask about timing cam sprockets
What does a cam sprocket do?
The cam sprocket is the toothed gear at the front of the camshaft that the timing chain or belt drives. It keeps the camshaft rotating in exact sync with the crankshaft so the valves open and close at the right moment relative to piston position.
What are signs of a worn cam sprocket?
Listen for timing chain rattle from the front of the engine (especially at cold startup), watch for misfire and timing-related codes (P0016, P0017), and look for loss of power. Severe wear can cause the chain to jump teeth and bend valves.
How much does it cost to replace a cam sprocket?
A timing set with both crank and cam sprockets plus chain runs $50-$200 from Cloyes, Melling, or Sealed Power. Shop labor is $400-$1,500 because the front cover, water pump, and crank pulley must come off. Total: $500-$2,000.
Should I replace the timing chain when I replace the cam sprocket?
Yes - always do both at the same time. The chain wears into the sprocket teeth and a new sprocket on an old chain will skip and mesh poorly. Most timing sets include both pieces and the crank sprocket for one price.
Can I replace just the cam sprocket?
Technically yes, but you'll be back inside the timing cover within a year. The labor cost dwarfs the parts cost, so do the whole timing set - cam sprocket, crank sprocket, and chain - in one job.
How long does a cam sprocket last?
Factory cam sprockets usually last 100,000-200,000 miles. Cheap powder-metal sprockets in some pushrod V8s can wear faster, especially with infrequent oil changes. Upgraded billet steel sprockets can outlast the engine.
Is a double-roller timing chain worth it?
For stock daily drivers, an OE-style single chain is fine. For performance builds, high-RPM engines, or vehicles that tow, a true-roller or double-roller chain offers more accurate timing and better durability for $50-$100 more.
Do I need to retime the engine after replacing the cam sprocket?
Yes - the cam sprocket must be installed with the timing marks aligned exactly to TDC #1 on the compression stroke. Even one tooth off causes drivability problems and CEL codes. Use the engine's specific timing diagram during reassembly.
