    The Boss Hog 47732 is an Out Law racing series torque converter for the GM TH350, and it also fits the TH400 with the proper flexplate and the Powerglide with a 30-spline turbo shaft. It runs a 2,200 to 2,800 RPM stall and is rated for up to 1,400 HP, built for power adders like nitrous, a turbo, a supercharger, or a trans brake. It adds CNC-machined anti-balloon plates and a whole back cover that is quenched and hardened, on a super lightweight 9.6 in core with a 30-spline CNC-machined turbine hub, a hardened chrome moly impeller hub, Torrington-style encased bearings, and a modified extreme-duty stator. Every unit is leak and pressure tested, digitally balanced, and made in the USA. It will not interchange with the lock-up TH350C.
