Enhance your trimmer’s performance with a genuine replacement spring

Keep your string trimmer running smoothly with the Pertresion 3660582001 trimmer head compression spring. This replacement part is designed to restore proper tension and alignment, helping to maintain consistent cutting power and reliable operation over time. Rather than a generic fix, this spring is built to fit specific STIHL 15" trimmer heads, delivering a dependable, factory-like feel after installation.

In real-world yard tasks, a well-tuned trimmer head can reduce downtime and frustration. When the head tension is correct, line feeds more predictably and the trimmer maintains steady contact with the vegetation, whether you’re edging a sidewalk, trimming around garden beds, or tackling stubborn weeds along fence lines. The result is a cleaner cut and less wear on other components, allowing you to finish projects more efficiently.

Key benefits at a glance

  • Perfect fit for STIHL 15" trimmers across listed models, with careful notes for AH1500 variants.
  • Durable construction designed to resist wear, corrosion, and fatigue for longer service life.
  • Direct replacement with no modifications required—follow your trimmer’s manual for quick installation.
  • Helps restore proper tension and alignment, reducing slippage and improving cutting consistency.
  • Genuine replacement meeting OEM specifications, available in 3/6/9 pack options for flexibility.

  • Older ST1500F or ST1500SF heads may use a different spring (AH1500). If your head requires AH1500, use part 3660650001.
  • Verify your trimmer model and head type before purchase to ensure correct fit.
