3.00″ 6 Rib ZPE GripTec® Whipple 5 Bolt L3V-A Black Pulley Only By Griptec

If your supercharger could dream, this is the pulley it would fantasize about while idling in traffic. We’re talking about a 3.00″ (76.20mm) GripTec®-equipped Whipple 5-bolt pulley made from billet 7075-T6 aluminum—which, in car nerd terms, means “absurdly strong and freakishly light.”

Not to dunk on 6061 (you tried, buddy), but 7075-T6 is the big dog of aerospace-grade aluminum. It’s harder, stronger, and makes this pulley feel like it could survive re-entry from orbit. Combine that with a black Type III anodized finish, and you’ve got a pulley that looks as mean as it performs.

And now, let’s talk about GripTec®, aka the reason you’ll stop crying about belt slip. This patented micro-machining wizardry bites into the belt just enough to hold tight without chewing it up. No more squeals, slips, or sad boost numbers. Just consistent, efficient power delivery that makes the most of every ounce of air your blower can stuff down your intake.

This bad boy rocks a 6-rib setup and is tuned to GripTec’s Level 3V-A, which sounds like a sci-fi laser but actually just means “maximum grip without belt murder.” It’s a simple bolt-on that delivers real gains—assuming, of course, you don’t forget to actually install it.

So if you’re running a Whipple setup and want your supercharger to stop spinning like it’s on a Slip ‘N Slide, this pulley is your new best friend.
