Key Benefits & Upgrades
Massive Torque Capacity: Safely handles over 1,625 Nm of torque, far exceeding factory limits.
Bulletproof Billet 7075 Hubs: Custom-designed, heat-treated, and hard-anodized C and E hubs replace the weak factory cast aluminum to completely eliminate sheared splines and clutch hang-ups.
Next-Gen FX-RT Friction Materials: Proprietary in-house developed friction discs deliver a significantly higher friction coefficient for crisp, slip-free shifts without harsh engagement.
Maximized Clutch Counts: Increased clutch count across every single clutch pack maximizes surface area and load distribution.
Pre-Clearanced for Easy DIY Setup: All clutch packs arrive pre-measured and ready to drop right in with custom pressure and apply plates—no guesswork required. (Extra steels included for builders who prefer custom clearances).
Enhanced Cooling: Re-engineered oil evacuation and cooling paths keep transmission temperatures in check under heavy load.
