Performance Crank and Accessory Pulleys
STILLEN has long manufactured precision pulleys for our
supercharger kits. We have used this expertise to produce a new
line of high performance crank and accessory pulleys.
Each pulley is machined from 6061 aerospace grade billet aluminum
with a bold new design to maximize performance, strength and
minimum weight. 304 stainless steel sleeves are used for main seal
contact points for durability. Stock timing marks are maintained
and keyways are precision broached. All pulleys are CNC turned,
milled and balanced based on computer generated designs.
Up to 80% lighter weight than stock steel and up to 10% lighter
than other aftermarket pulleys, we've seen power gains of up to 10+
HP at the wheels.
Both underdrive and stock diameter applications available for most
popular Nissan / Infiniti vehicles.
