Stihl 390 Chainsaw Buying Guide
A structured evaluation process is essential when shopping for Stihl 390 Chainsaw components because even small mismatches in specifications can reduce cutting speed or create safety risks. The following criteria focus on technical compatibility, durability metrics, and practical value derived directly from product dimensions and pricing.
Chain Pitch, Gauge, and Drive Link Compatibility
Chain specifications form the foundation of any Stihl 390 Chainsaw setup. Pitch determines how the chain engages the sprocket, while gauge must match the bar groove width exactly to prevent binding or derailment. Drive link count must align with bar length for proper tensioning. For example, a 0.325 inch pitch chain with 72 drive links suits a 20 inch bar, whereas 3/8 inch pitch options with 55 or 64 drive links fit shorter 12-16 inch bars. Selecting the wrong combination leads to accelerated wear on the drive sprocket and reduced power transfer. Always cross-reference the original MS390 bar length before purchase to maintain factory cutting geometry.
Skip-tooth and full-chisel designs further influence performance. Full-chisel skip-tooth chains excel in softwood and offer faster chip clearance for long bars, while semi-chisel variants provide longer edge life in dirty or hardwood conditions. When evaluating 15 options, calculate the effective cutting length by matching drive links to bar size: a 36 inch bar typically requires 114 drive links at 3/8 pitch and 0.050 gauge. This math ensures the chain seats correctly without excess slack that could cause kickback.
Carburetor and Ignition Kit Fitment
Carburetor kits address the frequent fuel delivery issues on high-hour Stihl 390-class engines. A complete kit that includes the carburetor body, gaskets, and ignition coil restores throttle response and cold-start reliability. Confirm the kit replaces the specific OEM number (such as 1128 120 0625) to avoid airflow mismatches that lean out the mixture and risk piston damage. Aftermarket kits priced near the lower end of $7.99 – $274.94 often include needle bearings and washers for the clutch side, reducing the need for separate purchases. Installation requires basic tools and careful jet cleaning to prevent recurrence of clogging from ethanol fuels.
Clutch, Sprocket, and Tensioner Durability
The clutch and sprocket assembly transmits engine torque to the chain and experiences high stress during repeated engagement. Look for 7-tooth precision designs that include needle bearings, washers, and E-clips for complete replacement of worn 1125-series parts. A matching chain tensioner adjuster ensures consistent bar pressure without binding. These components directly affect vibration levels and chain speed consistency. Brands offering full kits reduce downtime compared with sourcing individual pieces, and their inclusion of worm gears improves long-term reliability under farm and ranch loads typical of the MS390 platform. Explore additional category insights at the Chainsaws resource hub for broader platform comparisons.
Bar Length Matching and Power Delivery
Bar length must correspond to the engine displacement and intended work. Shorter 12-16 inch bars favor control for limbing and firewood processing, while 20-36 inch configurations suit felling and bucking larger diameter stock. The full chainsaw option with a 16 inch bar and chain provides a complete ready-to-use package, whereas separate long-bar chains require verification that the powerhead can maintain chain speed without bogging. Weight distribution also matters: longer bars shift the center of gravity forward, increasing operator fatigue during overhead work. Calculate required drive links first, then confirm the chain type (rapid super, picco micro mini, or skip tooth) matches the bar nose sprocket.
Brand Reliability and Value Across Price Tiers
OEM Stihl components deliver precise metallurgy and consistent heat treatment for chains and bars, while selected aftermarket brands focus on complete kits that include hardware often omitted in single-piece replacements. Value is measured by the number of included parts per dollar rather than lowest sticker price alone. Items at the bottom of $7.99 – $274.94 solve single-point failures such as tensioners, whereas mid-range multi-packs of long chains reduce per-unit cost for high-volume users. Cross-checking warranty language and material claims against the original equipment specifications protects against premature stretch or tooth breakage. For context on how similar Stihl models perform, see our detailed look at MS250 Stihl chainsaw specifications and user considerations.

Testing & Selection Methodology
Our comparison of 15 stihl 390 chainsaw options relies on systematic analysis of published technical specifications, dimensional compatibility data, and brand reliability indicators rather than uncontrolled field claims. Each item was evaluated against OEM reference numbers for the MS290, MS310, and MS390 family, including exact pitch, gauge, drive link counts, and replacement part codes. Pricing tiers from $7.99 to $274.94 were normalized to assess cost-per-component value, while packaging completeness (inclusion of bearings, washers, coils, or multi-packs) received weighted scoring for real-world utility.
Additional filters included material consistency for chains (full chisel versus semi-chisel), ease of installation based on kit contents, and alignment with common bar lengths of 12, 16, 20, and 36 inches. User satisfaction metrics were inferred solely from available product naming and fitment statements. This method ensures repeatable rankings focused on functional interchangeability and long-term serviceability for the target platform. Broader chainsaw category context is available via the Chainsaws category overview.

Frequently Asked Questions
What chain pitch and gauge work best for a Stihl 390 chainsaw?
Most Stihl 390 configurations use 0.325 inch or 3/8 inch pitch combined with 0.043 or 0.050 inch gauge depending on the original bar. Confirm the exact drive link count against bar length before ordering to ensure proper fit and tension. Matching these three measurements prevents premature sprocket wear and maintains cutting efficiency.
How do I know if a carburetor kit will fit my MS390?
Verify that the kit explicitly lists replacement of OEM part 1128 120 0625 or equivalent for the MS290/MS310/MS390 series. Kits that also include the ignition coil and gaskets restore both fuel metering and spark reliability in one installation. Cross-check the model stamp on the original carburetor body for final confirmation.
What is the typical price range for quality stihl 390 chainsaw parts?
Current options span $7.99 to $274.94, covering individual tensioners at the low end through complete saws and multi-pack long chains at the high end. Budget allocation should prioritize exact-fit critical wear items first, then expand to multi-packs for high-use scenarios. Additional platform details can be found in the Chainsaws category listings.
Can I use skip-tooth chains on a standard Stihl 390 bar?
Yes, provided the pitch, gauge, and drive link count match the bar exactly. Skip-tooth designs increase chip clearance and cutting speed in clean wood but require more power to maintain chain speed; the MS390 platform has sufficient displacement for 36 inch skip-tooth applications when properly tensioned and lubricated.
How often should clutch and sprocket assemblies be replaced on these models?
Inspect the clutch drum and sprocket teeth every 50-100 hours of use or whenever chain stretch exceeds adjustment range. Replace the full assembly including needle bearing and E-clip when teeth show hooking or the drum develops grooves. Kits that supply all hardware simplify the job and restore original engagement feel.
