Crank Pulley 1V-Groove - BBC Balancer

The POWERMASTER Crank Pulley 1V-Groove BBC Balancer (Part 295) is a precision-engineered crankshaft pulley designed specifically for big block Chevy engines requiring single-groove V-belt drive compatibility. This 5.25-inch diameter aluminum pulley delivers reliable harmonic balancing for high-output engine builds, street performance applications, and endurance driving scenarios where belt-driven accessory systems demand consistent rotational control.

The 1V-groove design accommodates standard V-belt configurations used on alternators, water pumps, and power steering systems common to big block Chevy platforms. Gray anodized aluminum construction provides corrosion resistance while maintaining the lightweight characteristics necessary for reducing parasitic drag on crankshaft rotation. At 1.22 pounds, this pulley minimizes rotational inertia without sacrificing the mass distribution required for effective harmonic damping. All necessary mounting hardware is included, eliminating the need for separate fastener sourcing during installation.

This crank pulley is engineered for engine builders, performance enthusiasts, and restoration specialists working with big block Chevy applications ranging from classic muscle car rebuilds to street rod and marine installations. The single-groove configuration suits vehicles running traditional serpentine alternatives or dedicated belt systems where multi-groove pulleys are unnecessary. Proper pulley selection prevents belt slippage, reduces accessory wear, and maintains consistent timing for engine management systems that rely on crankshaft position sensing through pulley-mounted reluctor rings.

POWERMASTER is recognized in the engine component aftermarket for balancer and pulley systems engineered to OEM tolerances. This BBC balancer pulley meets the dimensional and performance expectations established across the big block Chevy platform, ensuring drop-in compatibility with factory and upgraded engine bay configurations.
