LS1 SB V8 1.483" CRANK
COUNTERBORED TO ACCEPT DRIVE MANDREL

[4] Hubs for these assemblies have a 2.280 counterbore. A standard length crank bolt is used and the mandrel bolts to the 3 pulley mounting holes. This eliminates the 4" - 6" long bolt that is ineffective in retaining torque. Adapter part # 916321 is available for existing mandrels with 1.245" pilot.
