2.50″ 6 Rib ZPE GripTec® Whipple 5 Bolt L3V-A Black Pulley Only

Want more boost without the slip-n-slide drama? Say hello to the Whipple 5-Bolt Ultra Lightweight Pulley, engineered from 7075-T6 billet aluminum—that’s the aerospace stuff, which means it’s probably tougher than your in-laws’ Thanksgiving turkey.

At 2.50″ (or 63.5mm if you’re feeling metric), this pulley is the lightweight champ of the supercharger world. And we’re not just talking “lost a couple pounds before summer” lightweight—we mean seriously trimmed-down and tough-as-nails. Thanks to that high-grade 7075-T6 aluminum, it’s stronger and harder than the typical 6061 variety. You could probably throw it at a brick wall and worry more about the wall.

But let’s talk GripTec®. This pulley comes armed with Level 3V-A GripTec®, a fancy micro-machining technology that increases friction without shredding your belt like a salad spinner. Translation? More grip, no slip, no drama. Your belt stays put, your boost stays steady, and your ride stays rowdy.

The pulley features 6 ribs, is finished in a sleek black Type III anodized coat, and fits the Whipple 5-bolt pattern like a glove. It’s everything your supercharger’s ever wanted—besides maybe a thank-you note.

So if you’re chasing max performance, cleaner throttle response, and the kind of grip that would make a rock climber jealous, this is your move. Just don’t be surprised if your boost gauge starts asking for a raise.
