The updated BBT Pro Cup Socket tools all feature a unique design that allows you to switch between 24, 29 and 30mm inserts or a universal insert, depending on the application. The inner guide inserts simply snap-in to keep everything straight while installing and removing BB cups. Each snap-in insert features a 3/8 inch drive for use with a torque wrench or breaker bar. Spline cup options include: 52x16 (T47 & Torqtite BB386 and PF30), 46x12 (BSA 29 & 30), 44x16 (BSA24/FC32) & 41x16 (Maxhit BSA24/FC25). The entire tool is precision manufactured of the same aluminum alloy (6061 T6) as our BB cups to ensure secure, no-mar cup installation and removal.
