313318001 311759008 Replacement for Ryobi String Trimmer Trimmer Head Assembly P2009 RY15523A RY15523AVNM

What It Is

This is a replacement trimmer head assembly for Ryobi string trimmers, designed to hold and feed trimmer line for edging and grass cutting. It’s a direct-fit part for several popular Ryobi models, not a universal head.

Fitment & Compatibility

Before buying, confirm your trimmer model. This assembly fits Ryobi models P2009, RY15523A, and RY15523AVNM. It also works with other Ryobi trimmers using the same 313318001 or 311759008 OEM part numbers. Check your current head’s part number or look for a model sticker on your trimmer shaft. This is an aftermarket replacement, not OEM Ryobi, but dimensions (head diameter, mounting hole pattern) match the originals. No deck size or universal fit—it’s specific to these Ryobi bump-feed heads.

Key Things to Know

• Quality: Aftermarket, but rated 4.6/5 from over 2,000 reviews—most users find it as durable as OEM at half the price.
• Installation: Easy, tool-free swap in under 10 minutes. Remove old head (usually unscrews or depresses a tab), align and snap on new one. No special tools needed.
• Gotcha: Some users report bump-feed mechanism can be stiff initially; tap firmly on ground to advance line. Pre-wound with line, but you can reload with any 0.080” or 0.095” trimmer line if needed.
• Gotcha: Double-check your model number—some Ryobi trimmers use a different mounting system (e.g., straight shaft vs. curved shaft). This head is for curved-shaft models listed above.

Should You Buy It

If you own a Ryobi P2009, RY15523A, or RY15523AVNM and need a quick, affordable replacement for a worn or broken head, this is a solid pick. It’s not OEM, but the price and reviews make it a safe bet for DIYers who want to avoid a $30+ Ryobi part. Skip it if you have a different Ryobi model or want guaranteed factory fit.
