KAKEI 20 Inch Chainsaw Chain
Best For: Saws that require 3/8″ pitch, .050″ gauge, and 72 drive links. This KAKEI chain is a full chisel design with Germany steel and heat treatment aimed at toughness and flatness. It fits MS311, MS391, Husqvarna 455/460 Rancher, Poulan Pro and similar models. Use this if you want a consistent, aggressive cut on clean wood. The kit comes in a 3-pack, which helps reduce downtime from chain changes.
Selection rationale: The 72 drive links match common 20″ bars, and the chain’s heat-treated rivets are designed to resist wear and reduce chain tension changes. A caution is noted about kickback potential; operators should have training and experience with kickback scenarios.
Limitations: The warning about kickback means this chain is best for experienced users. Always verify pitch, gauge, and drive-link count from the bar and manual before installation.
Husqvarna X-Cut S83G 20 Inch Chain
Best For: Husqvarna 460 Rancher and 455 Rancher. This chain is designed for precision and ease of use, with a semi-chisel configuration that tolerates dirt well and stays sharp longer. It offers 72 drive links, 3/8″ pitch, and .050″ gauge, making it a solid choice for homeowners and professionals who want predictable, smooth cuts with lower maintenance.
Why selected: This chain is built in close alignment with Husqvarna equipment and emphasizes low kickback performance and maneuverability, reducing operator fatigue during longer sessions.
Caution: As a Husqvarna‑centric design, compatibility with non‑Husqvarna bars or sprockets should be confirmed before purchase.
Oregon 3-Pack 20 Inch Chain
Best For: A broad range of chainsaw brands and models that accept 3/8″ low-profile pitch with .050″ gauge and 72 drive links. This Oregon 3-pack is intended for a wide compatibility footprint, including Stihl, Husqvarna, Jonsered, and other brands that follow the same specs. It’s a solid fit for mixed-tool fleets or when stocking spare chains for multi‑saw usage.
Why selected: Oregon is known for broad compatibility and durable full-chisel configurations, offering straightforward installation and reliable performance across many saws.
Caution: Always confirm the exact drive-link count and bar compatibility with your model to avoid mismatches that can affect tension and cutting efficiency.
Savior 20 Inch Chainsaw Chain
Best For: Stihl MS311, MS391, and Husqvarna 455/460 Rancher models. Savior chains offer full chisel design with 72 drive links and 3/8″ pitch, .050″ gauge, and low-kickback features intended to reduce operator fatigue during longer cuts. This makes it a practical choice for versatile yard work and light‑to‑mid‑duty professional use.
Why selected: The chain provides broad OEM part number replacements and a flexible fit across several popular brands, helping simplify stocking decisions for mixed toolkits.

FIFCHANT 4 Pack 20 Inch Chain
Best For: Husqvarna 455 Rancher, 460 Rancher, Stihl MS391/MS311, and Poulan PR5020 models. This 4-pack provides 72 drive links, 3/8″ pitch, and .050″ gauge with a note that the chain length describes the bar length rather than the loop length. It’s suitable for routine yard tasks and occasional professional use.
Why selected: The set offers multiple chains in one purchase, enabling quick swaps and consistent performance across compatible models. The semi-chisel configuration supports smoother cutting in varied conditions.
Caution: Double-check bar length and sprocket compatibility, as incorrect pairing can affect tension and cutting efficiency. Some models require precise drive-link counts beyond the standard 72.
O-CONN 4 Pack 20 Inch Chain
Best For: A broad mix of 20″ bars across Husqvarna, Stihl, Poulan, Makita and more. The O-CONN four-pack emphasizes high durability with chrome outer layers and hardened rivets designed to reduce wear and frequent adjustments.
Why selected: The kit focuses on a wide brand range, making it easier to find a compatible option for diverse tool inventories while maintaining robust construction for long service life.
Caution: Confirm your chain’s drive-link count and bar compatibility, as mismatches can lead to improper tension and reduced cutting performance.
Buying Guide
What should you check before buying a 20″ chain with 72 drive links?
- Pitch: Ensure the chain uses 3/8″ pitch to match your bar and sprocket setup.
- Gauge: Verify a .050″ gauge for proper bar groove compatibility and safe operation.
- Drive links: Confirm 72 drive links to fit a 20″ bar length; some listings describe bar length differently, so measure bar length and count drive links carefully.
- Compatibility: Cross-check model compatibility with your saw brand (Stihl, Husqvarna, Stihl equivalents, Poulan, etc.).
- Kickback considerations: Some chains are labeled as low-kickback or semi-chisel; choose based on your comfort with kickback risk and maintenance capability.
- Material and finish: Look for chrome or hardened rivets and robust rivet systems for wear resistance and longer service life.
Compatibility and fit questions
- Is this chain compatible with my bar length and sprocket size?
- Does my saw require a low-kickback or standard high-performance chain?
- Are there model-specific requirements (e.g., Husqvarna vs Stihl) that limit cross-brand use?
Maintenance and safety
- Keep the chain sharp with proper filing or sharpening tools designed for 3/8″ pitch and .050″ gauge chains.
- Follow kickback safety practices and wear appropriate PPE during operation.
- Regularly inspect rivets and chain tension to prevent premature wear or derailment.
FAQ
- Q: Do 72 drive links always mean a 20″ bar?
- A: Not always. Drive link counts correlate with bar length and chain type; verify with the bar stamping and saw manual.
- Q: Can I mix chains from different brands on the same bar?
- A: Mixing brands is possible if pitch, gauge, and drive-link counts match; performance may vary.
- Q: What is the advantage of a full-chisel chain?
- A: Full-chisel chains cut faster on clean wood but can be more sensitive to dirt and require more frequent sharpening.
- Q: Should I choose a low-kickback chain?
- A: If you work in tight spaces or are less experienced, a low-kickback option can improve safety and reduce fatigue.
- Q: How do I verify fit before installing?
- A: Check the bar stamp for pitch, gauge, length, and drive-link number; compare with the chain you intend to install.
