Troy-Bilt chainsaw chain and guide bars by model

This guide lists all 12 Troy-Bilt model names recorded in our Saw Parts Finder, with the common chain and bar configurations from the Oregon 2026 Master Parts Catalog mapping. Use the Parts Finder button above to select your exact model. Always confirm pitch, gauge and drive-link count on the bar fitted to your saw.

Check before ordering: the same model can have different setups. Bar length alone is not enough. Match pitch, gauge, drive links and the bar mount, and confirm the drive sprocket. “Common” and “alternate” follow our finder’s catalog classification, not a guarantee of your factory equipment.

Every Troy-Bilt model name opens the Saw Parts Finder with that brand and model selected: Troy-Bilt TB3516, Troy-Bilt TB4016, Troy-Bilt TB4018, Troy-Bilt TB4216, Troy-Bilt TB4218, Troy-Bilt TB4516, Troy-Bilt TB4620, Troy-Bilt TB4920, Troy-Bilt TB5018, Troy-Bilt TB5020, Troy-Bilt TB5518, Troy-Bilt TBCS57.

How to confirm your chain

  1. Read the pitch and gauge markings on your current guide bar.
  2. Count the drive links on your old chain; do not count the cutters.
  3. Match the exact configuration in the finder, including bar mount and sprocket requirements.

Bar and part references are fitment information, not a live-stock statement. Use the finder for available store options. Never interchange .043, .050, .058 or .063 gauge chain without the correct matching bar.
