Brand new 4-point felling dog (bumper spike) – never installed, just stored (some light storage dust/grime, but fully cleanable and in excellent new condition – see close-up photos). Perfect direct replacement or upgrade for Stihl's large-frame / super-heavyweight chainsaws: 084, 088, MS 880, MS 881 series (and compatible variants). Key Specs & Features: Aggressive 4-prong / 4-point design for maximum bite and leverage – ideal for big timber, thick bark, or heavy-duty felling/milling. Long, straight base plate with precise 2.750 inches (70 mm) center-to-center mounting hole spacing – matches the wide bolt pattern on these high-displacement Stihl models (not compatible with narrower mid-size saws like MS 660/461). Heavy-duty steel construction – thicker and more robust than standard thin OEM spikes for better durability under stress. Overall length approx. 4.8 inches (123 mm) – provides superior reach and stability. Two mounting holes for secure fit on clutch cover (works as inner or outer side). Condition: New – stored only, no use, no damage, bends, or wear. Just needs a quick wipe-down (photos show real condition with caliper proof of fit). OEM reference: Compatible with Stihl part #1124 664 0506 (stock is often a simpler/single design; this is a beefed-up 4-point match). This is a great find for pros running these monster saws – bolts on easily, no mods required. Superior grip over stock for better control in tough cuts. Compatibility: Stihl 084 AV, 088, MS 880 Magnum, MS 881 (large-frame series). Double-check your saw's spacing if unsure – this is the wide 70 mm / 2.75" version.
