Left Coast 32 also markets these innovative RIP (Race Inspired Pulleys) blower pulleys that employ a lateral cut across the ribs of the pulley to create teeth that grip the belt and prevent slippage.

These belts are available through any Gates automotive outlet, but they are also a little more expensive at around $70 per belt.
