Overview

This aftermarket 20” bar and chain set is designed for chainsaw owners who want to restore full cutting capability in a single swap. Pairing a fresh bar with a new chain eliminates uneven rail wear and ensures the chain rides in a clean, properly dimensioned groove. The result is safer operation and cleaner cuts.

Key specifications

  • 20” guide bar and chain combo
  • Chain pitch: 3/8
  • 72 drive links
  • Matched bar and chain for optimal tracking
  • Low-kickback design for safer operation

Compatibility

This combo set is designed for various manufacturers chainsaws as listed above. Verify bar length, pitch, gauge, and drive link count match your saw’s requirements before purchasing.

Installation notes

With the saw fully powered down, remove the clutch cover and extract the old bar and chain. Install the new bar, route the new chain with proper orientation, and hand-tighten the bar nuts before final tensioning. New chains stretch quickly during the first few cuts, so re-check tension frequently during the break-in period.

Common questions

Q: Will this 20-inch guide bar and chain combo fit my chainsaw if the listing says “compatible with selected models” but I don’t see my exact model listed?

The safest way to confirm fitment is to match your current bar length, chain pitch, gauge, and drive link count to the specs shown in the listing. If one of those measurements is different, this combo may not tension or track correctly even if the saw brand looks similar.

Q: Does this 20-inch bar and chain combo come ready to install, and do I need to adjust chain tension after putting it on?

Yes, it is typically installed as a direct replacement bar and chain set, but you should still verify the chain is routed in the correct cutting direction before tightening the side cover. After installation, adjust the tension so the chain snaps back against the bar but still pulls around by hand, then recheck it after the first few minutes of use since a new chain can stretch slightly.

Q: What maintenance should I do to help this 20-inch guide bar and chain last longer on my saw?

Keep the chain properly sharpened, maintain bar oil flow, and clean the bar groove and oil holes regularly so the chain runs cool and straight. It’s also a good idea to flip the guide bar periodically to promote even wear and inspect the drive links and bar rails for burrs or uneven wear.

Before you buy — how to verify fitment

  1. Find your trimmer model number. It's usually on a label on the motor housing, battery slot, or lower shaft.
  2. Check spool compatibility. Compare the model number with the compatibility list above.
  3. Verify line gauge. Confirm the line thickness matches what your trimmer head requires by checking your manual or the old spool.
  4. Inspect the spool housing. Make sure the spool diameter, cap, spring post, and feed style match your trimmer head.

Frequently asked questions

How do I know this spool fits my trimmer?

Check your trimmer model number against the compatibility list above. Then verify the line gauge (.065, .080, .095) matches what your trimmer head requires — it's usually printed on the spool cap or in the manual.

Can I rewind a pre-wound spool?

Yes. Once the factory line runs out, you can rewind the spool with bulk trimmer line of the same gauge. Pre-wound spools just save time on the first load.

How often should I replace the spool?

Replace the spool when the line no longer feeds properly, the spring loses tension, or the spool body is cracked. Under normal weekend use, a spool lasts 2–4 refills before the housing wears out.

What gauge trimmer line should I use?

Match the gauge to your trimmer's power: .065" for light-duty electric trimmers, .080" for mid-range cordless, and .095" for gas-powered or heavy-duty models. Using too thick a line can stall the motor.
