Cloyes High Performance Engine Timing Chain P/N:9-304
Keep your crankshaft and camshaft turning in step with the CLOYES timing chain 9-133, a high-performance double-roller true roller chain designed to keep the engine's valve events in proper time. It fits many vehicles, among them the 1975-1981 Ford F-150 5.8L / 5.9L / 6.4L / 6.6L, 1987-1995 Jeep Wrangler 2.5L / 4.0L / 4.2L and 1968-1982 Ford F-250 5.8L / 5.9L / 6.4L / 6.6L. It is a direct-fit replacement for the listed applications, with engines such as the V8-5.8L, L6-4.2L and L4-2.5L. See the "Vehicles it fits" section for the full list.
The chain has no timing marks and is cataloged for the center position. The listed applications use one chain. Cloyes also offers 0.005-in. and 0.010-in. reduced-length versions; add -5 or -10 to the end of the part number to order one. When the chain is replaced, Cloyes recommends also replacing the chain tensioner(s), sprocket(s) and guide(s), because these components play a vital role in system stability and accurate timing.

What does an engine timing chain do?
It synchronizes the rotation of the crankshaft and camshaft so the engine's valve events are properly timed for each cylinder. The Cloyes 9-133 is a double-roller true roller chain built for that job.
Is this the right Ford F-150 timing chain for a 1975-1981 Ford F-150 5.8L / 5.9L / 6.4L / 6.6L?
It is listed for the 1975-1981 Ford F-150 with V8-5.8L, V8-5.9L, V8-6.4L and V8-6.6L engines, each for specific years. Check the "Vehicles it fits" section to match your year and engine.
What are the specifications of the Cloyes 9-133?
It has a 3/8-in. (9.5 mm) pitch, two rows, 64 links, a 0.250-in. roller diameter, a 12-in. (304.8 mm) length and a 23.6 mm (0.93 in.) width. The chain is steel and has no timing marks.
Should I replace other timing parts with the chain?
Cloyes recommends replacing the chain tensioner(s), sprocket(s) and guide(s) along with the chain, since they play a vital role in system stability and accurate timing. Part 9-133 is the chain itself.
What are signs a timing chain may need replacing?
Common signs include a rattling noise at start-up, rough running, or visible slack or wear found during inspection. These symptoms can have other causes, so diagnose the problem before replacing parts.
