Good To Know

Q: What does a timing chain damper do? A: It presses against the timing chain to control slack and keep camshaft timing consistent. A worn damper can cause rattle, timing drift, or accelerated chain wear.

Q: Should the damper be replaced with the chain? A: It is good practice to renew the damper whenever the timing chain is serviced. Confirm fitment for your specific model and model year before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
