Left Cassette Timing Chain Guide For 2001-2008 Ford Explorer, Ranger, Mazda B4000 4.0L

Got a 2001-2008 Ford Explorer, Ranger, or Mazda B4000 with the 4.0L engine?

If you're hearing a rattle from the front of the motor, the timing chain guides are a common failure point.

This is the left cassette-style timing chain guide, a direct OE-spec replacement from Fly-autopartsclub (part number 10017708).

It replaces several OEM numbers, including 90398SX and 7U3Z6A257A.

This is just the single part—the left guide—so make sure you're getting the right one for your repair.

It's a critical component that keeps the timing chain running smoothly and quietly.

Installing a new one can save your engine from serious damage.

It comes with a 1-year warranty for peace of mind.
