[2] All hubs have 3/16 key @ std SB 10° location. Please note: 8 groove & 10 groove shell assemblies are available for supercharger applications. Consult your ATI salesman. #917017 (7 1/2" diameter, 8 groove, steel) #917075 (6 3/4" diameter, 8 groove, aluminum)
[6] Damper assemblies have all countersunk bolts so nothing protrudes past front of damper. If you have an older damper and are ordering a new shell assembly only, you must cut a .090" x 45° chamfer on the front of your hub. ATI can also perform this operation for $40.
[13] 2010 LS3 Corvette Grand Sport coupes w/Manual Transmissions come equipped with a Dry Sump system, so an LS7 style damper is required.
