Description
 
The SmartShell is made of thicker material and the hub area is strengthened further with a steel collar that is precision welded to the shell. The splines are heat treated with a tested process to ensure strength and longevity. The lugs that engage the reverse drum are heat treated as well to avoid flaring. By replacing the black plastic washer with a thrust bearing and controlling the height of the modified OE race, the SmartShell reroutes thrust loads away from the captive rear planet bearing and sun gear. The rerouted end play / thrust loads pass through the new thrust bearing and modified roller clutch race directly to the rear planet carrier, completely bypassing the vulnerable captive rear planet bearing.
Smart Shell Features. Reinforced shell withstands torque load at the hub. Large bearing supports shell to withstand thrust load. Thrust load passes directly to the carrier from the shell through the large bearing and race, bypassing the small captured rear planetary bearing.
OEM. In addition to torque load damage, thrust load flexes and breaks shell at the hub bend. Thrust load passes from shell through the sun gear, then overloads the small captured rear planetary bearing.
