Description: Sonnax SmartShell® Heavy Duty Reaction Shell KitFits: 4L60 / 4L60E / 4L65E / 4L70E Includes:Heavy Duty Reaction Shell Enclosed Thrust Bearing Custom Roller Clutch Race In GM 4L60, 4L60-E, 4L65-E and 4L70-E units, bulky aftermarket shells always fall short when splines continue to strip and the shells break under stress. A chronic problem with both OE and thicker aftermarket shells is failure of the rear planetary bearing. From daily jobs to extreme builds, the Sonnax SmartShell heavy-duty reaction shell kit 77749-02K is the only way to prevent shell failure AND protect the bearing.The SmartShell avoids the weight found in traditional, heavy-duty aftermarket shells thanks to a unique combination of improved design and manufacturing for a super strength shell that's only slightly bulkier than OE. To prevent thrust loads from overwhelming the captured planetary bearing, the SmartShell features a larger bearing and custom roller clutch race. These parts re-route thrust loads through the carrier, completely bypassing the delicate bearing.Stops spline strippingPrevents hub breakageEliminates planetary bearing failure________________________________________Save a bundle here over the cost from a dealership Buy with confidence * Check out our feedbackAll of our items listed are in stock and ready to ship We Quick-Ship Every Day !
