Equip your extreme-displacement chainsaw for heavy timber felling, commercial logging, and sawmilling with the Genuine OEM STIHL .404" 7-Tooth Rim Sprocket Kit (Part #1124 007 1024). Engineered specifically for heavy-duty .404" pitch setups on STIHL's largest powerheads, this floating rim system allows the chain to align naturally with the guide bar groove—dramatically reducing friction, bar wear, and chain stress under massive pulling loads. This complete direct-fit replacement kit contains all key mounting hardware for a fast drive line overhaul.
Why Choose Genuine OEM over Aftermarket? Monster 100cc+ powerhouses like the 084, 088, and MS 880 generate immense rotational torque that quickly destroys sub-standard drive parts. Cheap aftermarket rim kits frequently feature soft steel rims that groove rapidly, out-of-spec drums, and weak retaining clips that risk catastrophic failure under extreme loads. STIHL OEM assemblies guarantee exact dynamic balance, precise needle bearing fitment, and maximum operational safety.

- (1) Heavy-Duty Clutch Drum
- (1) Replaceable .404" 7-Tooth Rim Sprocket
- (1) Precision Clutch Washer

Key Features
- 100% Genuine OEM STIHL Quality: Built from high-density, heat-treated structural steel alloys engineered to withstand severe commercial timber harvesting and milling operations.
- Heavy-Duty .404" Pitch 7-Tooth Profile: Calibrated specifically to handle the larger drive links, long guide bars, and extreme torque of professional .404" cutting systems.
- Self-Aligning Floating Rim: Keeps heavy chain drive links centered in the bar slot, extending both guide bar and chain service life while smoothing out overall operation.
- Cost-Effective Maintenance: Allows you to replace only the worn outer .404" rim sprocket during routine servicing rather than replacing the entire drum assembly.
