The Eaton Fuller K-3664 or K3664 is an Inertia Brake and Adapter Plate Kit designed for Eaton Fuller manual transmissions. This kit packages the inertia brake assembly and its corresponding adapter plate together as a single service unit, simplifying the replacement process at the bench. The inertia brake is a critical component that slows countershaft rotation during gear engagement, reducing clash and wear. If you need to confirm this kit is the correct fit for your specific transmission model, call Pro Gear and Transmission and we can help verify the application before you order.
