Powerbond 25% Underdrive Harmonic Balancer for LS1/LS6 1998-2002 Camaro and 2004-2006 Pontiac GTO - PBU1480SS25
Powerbond 25% Underdrive Crankshaft Pulley is SFI Approved.
Powerbond offers an affordable solution for those wanting to free up some additional horsepower with an underdrive balancer pulley. An underdrive balancer frees up additional horsepower by reducing parasitic drag from the accessory drive through slowing down the belt drive and reducing drag.
Underdrive pullies will require a shorter drive belt and a/c belt for proper belt tensioning since they feature a smaller pulley diameter.
