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) #917018 (7 1/2” diameter, 10 groove, steel) #917075 (6 3/4” diameter, 8 groove, aluminum) [3] [3] Requires shorter belts: Gates #K060775 - 6 rib, Goodyear #K040405 - 4 rib [4] Use hub part # 916033A for integral 8mm 28 tooth HTD pulley. [5] Contains 40 durometer rubber. Not for full race engines. Specify 66 rubber or call. [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” x45° chamfer on the front of your hub. ATI can also perform this operation for $40. |
