Overview

Available as a 2-pack, this chain is a direct replacement for Poulan Pro PR4218 / PP4218A / PP3516AVX and More Models models. A sharp chain means less effort, cleaner cuts, and safer operation compared to pushing through wood with worn teeth.

Key specifications

  • Bar length: 18”
  • Quantity: 2 chains per pack

Compatibility

Engineered for direct compatibility with Poulan Pro PR4218 / PP4218A / PP3516AVX and More Models. Always confirm your saw’s model number and bar length before ordering to ensure proper fit.

Installation notes

Power down the saw and disconnect the battery or spark plug lead. Remove the side cover and release bar tension. Take the old chain off the bar and sprocket, then thread the new chain into the bar groove, confirming the cutting edges face forward on the top rail. Set the tension so the chain pulls freely without sagging away from the bar, and do a brief test run to verify everything tracks correctly.

Common questions

Q: Will this 18-inch chain fit my Poulan Pro PR4218 and PP4218A, or do I need to match the old chain specs first?

Yes, this 2-pack is made for 18-inch setups used on models like the Poulan Pro PR4218 and PP4218A, but you should still confirm your original chain specs before installing. The safest method is to match the bar length and compare the markings on your current bar or chain so the pitch, gauge, and drive link count line up correctly.

Q: Can I use this replacement chain on my Poulan Pro PP3516AVX if I have an 18-inch bar installed?

It can work on a PP3516AVX only if that saw is actually running an 18-inch compatible bar and the chain specifications match what this replacement requires. Model compatibility can vary depending on the bar currently installed, so checking the bar stamp or owner’s manual is the best way to verify fitment.

Q: What should I do before running these new chains for the first time, and how often should I retension them?

Before first use, make sure the chain is installed in the correct cutting direction, seated fully in the bar groove, and adjusted so it’s snug but still pulls around by hand with gloves on. New chains usually stretch a little during the first few cuts, so check tension frequently at the start and keep the chain oiled to reduce wear on both the chain and bar.

Before you buy — how to verify fitment

  1. Find the bar stamp. Look on the side of your current guide bar for the pitch, gauge, and drive-link count.
  2. Match all three numbers. Pitch (3/8 LP), gauge (.050"), and drive links (62DL) must all match.
  3. Check bar length. Measure cutting length from the tip to where the bar enters the saw body — this should match 18".
  4. Confirm your saw model against the compatibility list above. If your model isn't listed, the chain may still fit if pitch/gauge/DL match.

Frequently asked questions

How do I know this chain fits my saw?

Match three numbers: pitch, gauge, and drive-link count. All three must match the stamp on your current bar. If even one is off, the chain won't fit safely.

How do I measure pitch and gauge?

Pitch is the distance between any three consecutive rivets, divided by two. Gauge is the thickness of the drive links — measure with a caliper or check the bar stamp. Our guide covers both in detail.

How long does a replacement chain last?

With proper tension and occasional sharpening, an aftermarket chain lasts 3–5 cords of firewood or about 5 hours of active cutting — roughly the same as OEM.

Can I sharpen this chain or is it single-use?

Absolutely sharpen it. A quality replacement chain can be sharpened 3–5 times before the cutters are too short. Keep a round file matched to the cutter diameter.
