This billet aluminum stock-sized pulley is a handsome addition to any engine. For engines that are driven off-road, or even street engines that launch hard, they can keep the dust and sand from entering the engine case, and to keep the oil from spilling out during hard acceleration and during bumpy rides.  This SACO pulley is made in the USA and has been a proven leader for decades in the VW community.  The billet aluminum pulley features laser-engraved degree numbers, and a hardened chromoly inner hub for utmost strength, best resistance to wear, and awesome looks.  

Comes with a machine-in sand seal, but can be used on a stock case with a special sand-sealed collar that slips into a stock case.  Requires use of a longer pulley bolt.
