DUAL PULLEY UPGRADE

This 188mm crank pulley is designed to be combined with an IE 57.5mm supercharger pulley (IEBAVJ1C) to upgrade your existing single pulley setup for stage 2 dual pulley tunes.

If you do not have an upgraded supercharger pulley and want to jump straight to Stage 2 double pulley power, the 207mm crank pulley IEBAVJ6 can be used instead without the need to purchase a smaller press-on SC pulley.

CRANK PULLEY & DAMPER

This complete one-piece pulley replaces both the crank pulley and factory engine damper in one unit. Replacing the engine damper provides increased reliability and protection from a possible faulty stock engine damper that is known to separate, causing costly engine damage.
