Stage X Dayco Timing Belt Kit & Triple Alloy Camshaft Pulley Upgrade Kit 99-02MY EJ20/22/25

This Stage X timing belt kit combines a Dayco timing belt with the same high-quality OE components used by vehicle manufacturers, and adds alloy camshaft pulleys. It is suitable for standard, lightly modified and heavily modified engines.

One weak area on Subaru EJ series engines is the plastic Bakelite camshaft drive pulleys. Over time they become brittle and eventually fail, causing catastrophic failure and internal engine damage. The aluminium camshaft pulleys included in this kit replace them.

For more extreme power levels and applications, a Motorsport tensioner upgrade with increased load actuation is also available for this kit.
