Adjustable Pulleys Skunk2 Pro Series - Séries H

An engine's camshafts must be set to their proper position relative to the crankshaft to maximize power. Skunk2 Pro Series adjustable pulleys allow serious tuners to optimize horsepower and torque by adjusting camshaft timing +/- 10 degrees in one degree increments. Thanks to the laser-etched dial and directional markings, precise camshaft adjustments can be made quickly and easily. Pro Series pulley gears feature hard anodized, precision machined teeth to reduce premature wear. The six-bolt design helps eliminate unintentional unwinding. Skunk2's lightweight design (35% lighter than stock) and CNC machined 7075-T6 aluminum construction reduces rotational inertia, increasing engine response and acceleration. Skunk2's adjustable pulleys have also been proven on race cars in the most extreme conditions for over a decade.
