3/8" LP · .043" · 40 DL chain: which saws it fits

A 3/8" Low Profile pitch, .043" gauge chain with 40 drive links. It is most often found on 10" bars, and fits 167 chainsaw and pole-saw models from 12 brands in Oregon's fitment data. Bar length alone doesn't decide fit — all three numbers have to match your saw.

Confirm it's your size

Read the bar stamp. Near the tail of the guide bar you'll usually find pitch, gauge and drive links, e.g. 3/8 LP .043 40. Some bars stamp the Oregon bar number instead — look it up on oregonproducts.com.
Count the drive links on your old chain — the teeth that ride inside the bar groove, not the cutters. It must be exactly 40.
Low profile is not full profile. 3/8" LP and 3/8" full-profile chains share the "3/8" but are not interchangeable.
If the stamp is worn off, the owner's manual lists the bar and chain; find it on the manufacturer's support site.

Easy to mix up with

3/8" LP · .043" · 39 DL — same pitch and gauge, shorter loop (usually 10" bars)
3/8" LP · .043" · 44 DL — same pitch and gauge, longer loop (usually 12" bars)
3/8" LP · .050" · 40 DL — same pitch and length, thicker drive links; it won't sit right in a .043" groove

Source: Oregon part-finder fitment data, retrieved 2026-07-06. We list a model here when Oregon recommends a 3/8" LP · .043" · 40 DL chain for one of its bar lengths; we haven't fitted each saw ourselves. Some bar configurations in the source don't give a drive-link count and aren't included — if your saw isn't listed, count your chain.
