Revitalize Your Trimmer with a Genuine Pertresion Spring

Refresh the efficiency of your string trimmer with the Pertresion 3660582001 trimmer head compression spring. This genuine replacement part is engineered to restore proper tension in 15" trimmer heads, supporting smooth operation and reliable cutting power across a range of Ego and STIHL models. Instead of forcing a fix, imagine a replacement that helps your trimmer feed line consistently and respond crisply when you pass near edging, fences, or thick clumps of grass.

Designed for performance in everyday yard tasks, this spring blends sturdy construction with a precise fit, aiming to reduce slippage and improve overall cutting consistency. While not a guarantee, many users notice a more predictable line feed and steadier performance after installation.

Key Benefits

  • Perfect fit for multiple STIHL and Ego models, including ST1500, ST1500F, ST1510S, ST1520, and STA1500 15" trimmers.
  • Durable construction uses premium materials to resist wear, corrosion, and fatigue during regular yard work.
  • Easy installation is a direct replacement with no modifications required, following your trimmer’s manual.
  • Restores efficiency by helping maintain proper tension and alignment of the head for consistent cuts.
  • Genuine replacement designed to OEM specifications, offered in 3, 6, or 9 pack options to suit ongoing maintenance.

What You Get and Pack Options

  • Choose from 3, 6, or 9 springs in a single order for flexible replacement planning.
  • Each pack contains a genuine 3660582001 compression spring designed for reliable pairing with compatible heads.

Compatibility and Quick Tips

  • Before purchasing, verify your trimmer model number and head type to ensure a correct fit.
  • Older ST1500F/ST1500SF heads may use a different spring (AH1500). If your head has green alignment lines, you may need part 3660650001 instead.
  • For a smooth replacement, consult your trimmer’s manual and follow the standard installation steps.

Upgrade your outdoor gear with a replacement that is built to support regular maintenance and dependable performance. This Pertresion spring is a practical choice for DIY upkeep and future-proofing your trimming workflow.
