NEO-TEC 36-inch Guide Bar & Chain Combo — 3/8 pitch, 0.063 gauge, 114 Drive Links (D025)

NEO-TEC's 36-inch replacement guide bar and matching 3/8" pitch, 0.063" gauge chain with 114 drive links is a direct-fit aftermarket combo designed to replace worn bars and chains on many Stihl and Oregon-compatible saws.

This combo pairs a heavy-duty 36" guide bar with a 3/8" pitch, 0.063" gauge chain (114 drive links) to restore cutting reach and performance on large-displacement saws. Manufactured to meet OEM-style dimensions, the bar is specified for tail mount D025 (12.1 mm / 0.475") installations and is intended as a durable replacement for Stihl and Oregon-equivalent long bars. NEO-TEC emphasizes material quality and testing to deliver parts that fit precisely and last through demanding jobs like milling, large-tree felling and processing storm-damaged timber.

Will this bar and chain fit my Stihl saw model?

Yes — the combo is engineered to match the dimensions used by many Stihl models that accept a 36" bar and require a 3/8" pitch, 0.063" gauge chain with 114 drive links. Confirm your saw’s bar mount type (D025 tail mount) and drive link count before ordering for a correct fit.

• Compatible with many Stihl MS and larger series (examples: MS660, MS661, MS460 series)
• Designed to work with Oregon-equivalent 363RNDD025 specifications
• Tail mount dimension: D025, 12.1 mm (0.475")
• Chain: 3/8" pitch, 0.063" gauge, 114 drive links

How does this replacement improve cutting for big jobs?

The longer 36" bar increases reach and makes it possible to cut larger diameter logs without specialized equipment. Paired with the correctly sized chain, it re-establishes consistent depth-of-cut and feed control so your saw can handle heavy-duty felling and bucking tasks more effectively.

• Extends cutting diameter capability for single-pass cuts
• Restores factory chain engagement and tension range for stable cutting
• Durable construction aimed at resisting wear during prolonged use
• Suitable for pro and heavy-duty homeowner applications

What should I check before installation?

Measure your existing bar and chain to verify pitch, gauge and drive link count match this combo. Also inspect the bar mount type (D025 tail mount) and ensure your saw’s chain tensioning and oiling systems are functioning properly for safe use.

• Confirm chain pitch: 3/8" and gauge: 0.063"
• Count drive links: 114DL required
• Check tail mount: D025 (12.1 mm / 0.475") compatibility
• Test oil delivery and tension mechanism before cutting

Who is this for? This NEO-TEC 36" guide bar and matching chain suit professional arborists, loggers, sawmill operators and serious landowners using high-displacement Stihl-style saws who need a reliable long-bar replacement. If you run cutting tasks that demand extended reach and robust, OEM-dimensioned replacement parts — such as large-tree felling, processing oversized rounds, or storm cleanup — this combo restores capacity without costly machine changes. It’s not intended for light consumer saws; confirm model compatibility first to ensure safe, effective performance.
