UpStart Components 16-Inch Chainsaw Replacement Chains — 6-Pack for Stihl 61PMM3, 3/8in LP .043 Gauge

UpStart Components 16-inch replacement chains — 6 high-performance chains compatible with Stihl 61PMM3 and models that accept 3/8" low-profile pitch, .043" gauge, and 55 drive links.

If your chainsaw is running slow, producing rough cuts, or the chain is visibly worn, replacing the chain is a simple way to restore cutting performance. This six-piece set gives you multiple fresh chains so you can swap out dull blades quickly, reduce downtime, and maintain steady cutting power for routine pruning, firewood preparation, or jobsite tasks. Each chain is built to balance cutting efficiency, reduced vibration, and longevity for everyday homeowner and light-professional use.

How do I confirm this chain fits my saw?

Measure three key dimensions on the bar or the worn chain: pitch, gauge, and number of drive links. The UpStart Components chains in this pack are 3/8" low-profile pitch, .043" gauge, and have 55 drive links—commonly used on 16-inch bars that accept Stihl 61PMM3 style chains.

• Pitch: 3/8" low-profile (measure the distance between three rivets divided by two).
• Gauge: .043" (thickness of the drive link that sits in the guide bar groove).
• Drive links: 55 (count the links that fit into the bar slot).
• Always compare your current chain’s markings or the owner’s manual before buying.

What performance improvements can I expect?

Fresh chains cut cleaner and with less effort than dull ones. These chains are engineered for smoother cuts and reduced vibration, which helps lessen operator fatigue and promotes steadier control during prolonged use.

• Smoother cutting action for faster work on limbs and small logs.
• Lower vibration levels for improved comfort and control.
• Durable steel construction designed to hold an edge longer between sharpenings.
• Sold as a 6-pack to keep spare chains on hand for quick swaps.

How should I install and maintain these replacement chains?

Installation follows the same basic steps as other chains: align the drive links in the bar groove, fit the chain around the sprocket, and tension according to the saw manufacturer’s guidelines. Regular maintenance—correct tension, frequent lubrication, and timely sharpening—preserves cutting efficiency and extends chain life.

• Install on a cool, stopped saw; follow the saw’s manual for tensioning specs.
• Use proper bar oil and keep the bar groove clean to prevent premature wear.
• Sharpen cutters or have them professionally serviced as needed.
• Replace chain immediately if damaged, excessively worn, or bent.

Are there safety considerations when using replacement chains?

Yes. A correctly matched, well-maintained chain reduces the chance of kickback and other hazards, but safe operation still depends on proper equipment use. Always follow chainsaw safety practices, wear personal protective equipment, and inspect the chain and bar before each use.

• Wear eye, ear, leg, and hand protection when operating the saw.
• Check the chain tension and bar oil level before starting the saw.
• Do not use a chain that doesn’t match the bar’s pitch, gauge, or link count.
• Keep bystanders clear and follow manufacturer safety guidance.

Who this is for: This 6-pack from UpStart Components is ideal for homeowners, landscapers, and small-scale contractors who use 16-inch chainsaw bars that accept a 3/8" low-profile, .043" gauge, 55-link chain—especially those who prefer to keep multiple fresh chains available for uninterrupted work days. It’s a cost-effective option for anyone who wants reliable replacement chains engineered for smoother cutting, reduced vibration, and longer-lasting performance between sharpenings.
