Engineered to surpass the limitations of stock components, these kits deliver an exceptional torque capacity of over 1000 ft-lbs. This comprehensive upgrade features advanced friction materials developed in-house, billet 7075 heat-treated and hard-anodized custom-designed C and E hubs, bespoke pressure plates, apply plates, and increased clutch counts for every clutch pack.\u003c\/p\u003e\n\u003ch3\u003eAdvanced Hub Design\u003c\/h3\u003e\n\u003cp\u003eThe C and E clutch hubs in the 8HP series are critical points of failure due to their OEM construction from weak, cast A380 aluminum. These components are prone to shearing or breaking of the lock splines, and the steel clutch plates can dig into the splines, causing hang-ups and burnouts.\u003c\/p\u003e\n\u003cp\u003eKey Upgrades:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial: Re-engineered using 7075 series aluminum, one of the highest grades of billet aluminum.\u003c\/li\u003e\n\u003cli\u003eTreatment: Heat-treated and hard-anodized to enhance strength and surface hardness, providing superior resistance to shear forces and wear from steel disc engagement.\u003c\/li\u003e\n\u003cli\u003eDesign Enhancements: Improved clutch cooling paths, oil evacuation, and increased clutch pack area for optimized performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSuperior Friction Materials\u003c\/h3\u003e\n\u003cp\u003eOur FX-RT frictions, developed in-house, offer significantly higher friction coefficients than OEM materials.
