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 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.

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.

LIGHTWEIGHT DESIGN

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.

MADE IN THE USA

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.

QUALITY FINISH

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.  

Installing your new pulley is straightforward and hassle-free with the proper tools. Although installation requires using a grinder to remove an unused small metal post from the engine block, the installation is typically easier than press-fitting on a supercharger pulley.

Install time around 2-3 hours

*2016-2018 A6 & A7 CREC 3.0T engines do not have compatible IE software support for 207mm lower crank pulley. IE single pulley CREC tunes safely produce typical dual pulley ratio numbers on this platform. Running 207mm or dual pulley ratio setups may cause supercharger clutch failure on CREC engines and is not recommended. CREC engine is also found in ROW (rest-of-world) markets on some late-model S4 & S5 3.0T as well. CREC engines are easily identified as the supercharger pulley has 4 bolts to attach it to the supercharger instead of a press-fit style.

Actually, better than I expected!
Size: Medium, Unit Count: 4
These are better than what I was expecting based on the reviews. I do put them on carefully because someone said you can’t tear them so I’m careful putting them on, but they almost don’t feel like you’re wearing anything as long as you don’t put them too tight on your toes. I can put lotion on my feet and I know it has to soak in because there’s no place else for it to go like socks or my bed.

So so...
Size: Medium, Unit Count: 2
They do what they advertised. You can NOT walk in them you will stretch them and pop a hole in them. You cannot sleep in them unless your going to wear larger cotton socks with them to keep them in place. They are easy to wash and dry which is nice. I will need to buy another pair. Great if your gonna watch a movie or binge TV in.

Great for dry feet or to help lock in moisturizer or medication
Size: Medium, Unit Count: 2, Size: Medium, Unit Count: 2
They’re stretchy and don’t feel goopy, I use them daily and they’re working great they keep my feet nice and hydrated and soft. I’ve been using them along with lotion to help hydrate my skin so they aren’t rough during the winter. They are comfy and if you must get up they’re grippy and don’t slip or slide they stay put. They’re super easy to put on and take off.
