Subaru EZ30 Master Timing & Water Pump Service Kit

The Definitive "Engine-Out" Solution for the H6 Platform.

The Subaru EZ30 3.0L Flat-6 is a masterpiece of engineering, but it is notoriously unforgiving when it comes to timing maintenance. Unlike the simpler EJ series, the EZ30 utilizes a complex dual-chain system that relies on perfect oil pressure and tensioner integrity.

By the time you hear the "H6 rattle" on a cold start, the damage to your guides is likely already done.

The Roo Racing Master Kit is a zero-compromise package. We have curated every single genuine component required to refresh the timing system and the internal water pump simultaneously. Because the EZ30 requires extensive labor (often engine-out) to access these components, the "while you're in there" philosophy isn't just a suggestion - it’s a financial necessity.

Why This Kit?

• Genuine Reliability: We use only Genuine Subaru components. Aftermarket EZ30 tensioners are a known failure point in the enthusiast community; we don't risk your engine on them.
• The Full Hardware Suite: Most kits skip the bolts. We include 47 critical socket and flange bolts, ensuring you aren't reusing stretched or heat-cycled factory hardware.
• Internal Water Pump Included: The water pump on the EZ30 is driven by the timing chain. If it leaks or seizes, the labor to reach it is identical to a timing job. We include the latest revision pump and O-ring as standard.
• Comprehensive Sealing: Includes the essential cylinder head sealing washers and oil seals often overlooked in basic kits.
