About This Product

If your Milwaukee-Eight is starting to slip, this Barnett Extra Plate clutch kit is the fix. Designed for 2017 to 2026 M8 models equipped with the assist and slip clutch, this kit includes 11 Aramid friction plates, 10 steel plates, and a set of heavy-duty springs. The extra plate design increases the overall friction surface area, which is crucial for handling the torque of a big V-Twin. It is a direct replacement for OEM part 37000258 and provides a much more positive engagement than the stock setup. Whether you are riding hard or just want more reliability, this kit delivers the durability Barnett is known for.

Manufacturer part number: 304-30-10020.
