This converter is designed for high performance street and strip applications which will benefit from the use of a lock up converter based on the OEM 12" platform. This converter will handle up to 500 foot pounds of torque in the recommended applications, and is available in low, medium and high stall configurations. Rated stall speeds are approximate, however, our extensive experience with this design allows it to be very predictable with a given engine combination. In general, engines producing up to 350 foot pounds of torque will favor the lower end of the advertised stall speed rating, and engines producing between 350 and 500 foot pounds of torque will favor or exceed the higher end of the advertised stall speed rating. High torque engines combined in heavy vehicles (3800 lbs. and up) and good braking systems will almost always reach the maximum advertised stall speed. The converter pump is fully furnace brazed to handle the additional torque multiplication provided by the stator assembly. A forged and flanged pump drive hub stops drive hub fatigue failures and oil leaks at the welded interface between the hub and cover. OEM thrust washers are replaced with high capacity thrust bearing assemblies for increased load bearing capacity. A heavy duty lock up clutch ensures quick and complete lock up, removing all slippage present in the fluid coupling.
