If your Stihl trimmer is vibrating weird, making grinding noises, or the head just won't spin right, the gear box might be shot.
Don't scrap the whole trimmer—swap out the gear head with this new one from ALL-CARB.\n\nThis is a replacement gear box head, the part that transfers power from the shaft down to the trimmer head.
It's designed to fit a wide range of Stihl models, including the FS260R, FS65-4, FS44, FS74, FS25-4, and even the FS250, FS250 R, and FS44 R.
It also fits several brushcutters and clearing saws like the FR130 T, FR220, FR350, and more.
It's a direct match for the Stihl part number 4137 640 0100.\n\nIt's a brand new unit, comes with a 1-year warranty, and is ready to bolt on.
Just make sure your model is in the compatibility list before ordering.
A fresh gear box means smooth, reliable operation all season long.
