many of these trucks are modified and therefore require a performance transmission to help deliver this power to the road. Friction counts have been increased in K2, K3, and B1 clutch packs to improve transmission torque capacity. To handle this increased torque capacity, the Torquemaster utilizes a custom billet nitride K2 hub and a billet K2 apply piston, which resists excessive spline wear found on the factory K2 hub. A billet K3 hub and piston are used in the K3 pack for increased durability, alongside the 40% increase in clutches. The billet K3 drum also resists ring grooving far better than the factory drum. Frictions used in aftermarket rebuilds commonly compromise shift quality
