Big Block Hub Adapter

$79.95

This is a CNC machined billet hub that bolts to the flywheel of the big block Briggs Vanguard horizontal engine.  The hub features a 1-1/2 center pilot, a 3 bolt 5/16-18 on a 3” BC. This is the bolt pattern that our universal pulley and our billet PTO shaft has. The hub also has a 4 bolt ¼-20 on a 2-3/16 BC. This is the standard pattern that Cub Cadet uses on the clutch pin style drivers and the hydro drive hubs. Includes the hub and 4 mounting bolts.

Please note: There are 2 options for bolts. 5/16-18 and 8mm x 1.25. You will need to figure out what thread size is in your flywheel. There is no way for us to know.
