Genuine Subaru Undertray & Splash Guard Bolt Set (4-Pack)

The Essential Anti-Corrosion Refresh for All Subaru Models 1990–2021.

If you’ve ever struggled with a vibrating undertray or had to zip-tie your splash guard back into place because the original bolts snapped, this is the definitive fix. Reusing rusted hardware isn't just a hassle for your next oil change; it risks the tray falling at high speeds, which can cause significant aerodynamic drag or damage to your front lip.

This Genuine Subaru Flange Bolt set features the factory-correct thread pitch and integrated washer design, ensuring a spread-load grip that won't vibrate loose on corrugated roads or during high-performance driving.

Why the Roo Racing Hardware Set?

• Factory-Spec Metallurgy: Sourced directly from Subaru, these bolts feature the specific yellow-zinc or olive-drab coating designed to survive the high-moisture environment under the engine.

• Integrated Flange Design: The wide-flange head acts as a built-in washer, distributing pressure across the plastic undertray to prevent the common "pull-through" cracking associated with standard hardware store bolts.

• Serviceability: Refreshing these bolts transforms a 10-minute oil change from a nightmare of rounded bolt heads into a seamless professional service.

🛡️ The Roo Racing Heritage Tip

To prevent these from seizing ever again, we recommend a tiny dab of nickel anti-seize on the threads before installation. This is especially critical for Australian owners in coastal areas where salt spray can "weld" steel bolts into the captive nuts of the subframe.
