T-40 Plus Torx Bit
ATI dampers are assembled with T-40 Plus countersunk bolts for the strongest possible mechanical connection of the shell assembly to the crankshaft hub. Also known as IP-40 Torx-Plus Insert Bit, the T-40 Plus must be used in lieu of a regular Torx bit for these bolts as the Torx head is designed for maximum strength when removing the bolt.
