These converters have many of the same performance characteristics as the Saturday Night Special Series for the cars, but are built with extra reinforcements and thicker mounting surfaces to withstand the additional load and vibrations put through the drivetrain by a modified off-road 4x4 truck. By providing additional stall, your truck will see better initial takeoff and will not lug the engine when using large diameter tires. Special attention has been made to match the converter to the power range of most trucks that do double duty as a daily driver and an off-road warrior.
