*** IN STOCK SHIPS TODAY *** For the racer that is going to service their ATI dampner this Torx bit is a must have. ATI dampers are assembled with T-40 Plus countersunk bolts for the strongest possible mechanical connection of the steel assembly to the crankshaft hub. ATI T-40 Plus Torx bits must be used instead of regular Torx bits for easier removal of the T-40 countersunk bolts.
Another bonus of this tool is if you run an RCD BAE type gear drive you can use this Torx bit to remove the idler gear plate to service the gear drive.
