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 a 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.

Weighing in at only 1613 grams, IE engineers have produced a robust pulley while trimming as much fat as possible without risking the structural design. The aluminum construction is 59% lighter than the stock setup, reducing rotating mass, resulting in faster engine revs and less parasitic loss.

The 6061-T6 aluminum pulley is finished with an attractive black anodized finish. The anodizing process offers superior protection against corrosion while retaining the proper installation clearances. After applying the coating, the alignment marks, part number, and logo are laser etched to guarantee long life and a fantastic look.  

This one-piece design delivers significant power and is a vital link that holds your engine and supercharger together. Enjoy the peace of mind knowing your pulley is 100% in-house designed and CNC machined from top-of-the-line sourced aluminum alloy followed by extensive quality-control.
