The Boss Hog 48453 is a Street Bandit series lock-up torque converter for the GM 700R4 (298mm) automatic transmission, on the 30-spline three-step input shaft. It runs a 2,800 to 3,200 RPM stall and is a super lightweight lock-up converter, in some cases more than 22 lb lighter than stock, which cuts rotational mass for quicker response. It strengthens the factory weak points with a thicker, stronger lock-up liner and a modified heavy-duty stator, and the design deletes the need for the end-of-input-shaft O-ring by sealing the lock-up on the back of the turbine hub. It uses a 9.6 in core, a 10.75 in bolt circle, and a 1.703 in crank pilot. Every unit is leak and pressure tested, digitally balanced, and made in the USA.
