What makes the Rapid Super chain different from standard chains?

Its cutter geometry and manufacturing tolerances are optimized for aggressive feed rates without sacrificing control. Because it’s an OEM Stihl part, you also get precise fitment and quality that matches original equipment specifications.

• Aggressive cutter profile for faster wood removal
• Precision-machined cutters for consistent tooth geometry
• Optimized rivet and link tolerances for long-term fit
• Pack of two chains gives an immediate spare for uninterrupted work

How do I confirm this chain fits my saw?

Identify the chain pitch, gauge, and number of drive links printed on your bar or in the saw’s manual to match with .325" pitch, .063" gauge, and 68 drive links. Cross-check the OEM part number 3639 005 0068 or 26RS-68 against your owner’s manual or dealer parts list to be certain. If in doubt, consult an authorized Stihl dealer for verification before installation.

• Check the bar stamp or owner's manual for pitch and gauge
• Match drive link count to 68 links for correct fit
• Use the OEM part number 3639 005 0068 to confirm compatibility
• Ask a Stihl dealer for help if uncertain

What should I know about installation and safe use?

Always follow the saw manufacturer’s installation instructions and safety guidance when replacing a chain. Wear protective gloves to avoid cuts while handling the chain, and use recommended tools and torque settings for the bar and sprocket cover. Regular tension checks, proper lubrication, and routine sharpening will keep the chain cutting efficiently and extend its service life.

• Wear cut-resistant gloves during installation
• Set correct chain tension per the owner’s manual
• Use bar and chain oil for proper lubrication
• Sharpen periodically and inspect for wear or damage

How long will a pack of two chains last in regular use?

Chain life depends on cutting material, maintenance, sharpening frequency, and operator technique, so longevity varies widely. With proper tensioning, lubrication, and timely sharpening, users often get many hours of productive cutting from each chain. Having a two-chain pack lets you rotate a fresh chain in quickly to maintain consistent cutting performance on longer jobs.

• Longevity influenced by wood type and debris exposure
• Regular sharpening preserves cutting speed and reduces wear
• Keeping chain lubricated lowers friction and extends life
• Second chain in pack minimizes downtime on long jobs

Who is this for? The Stihl 3639 005 0068 Rapid Super chain pack is aimed at professional arborists, landscapers, and serious homeowners who need a reliable, fast-cutting replacement that meets OEM specifications. If you require precise fitment, predictable cutting behavior, and the convenience of a spare chain, this Stihl pack delivers a ready-to-use option. Always verify fitment against your saw’s manual and follow safety guidance when installing or operating the equipment.
