Product Details

The March Performance 4021-08 is a precision-engineered black anodized aluminum crankshaft pulley assembly designed specifically for 1985-1987 Chevrolet small block 305 and 350 cubic inch engines. This pulley replaces the factory harmonic balancer pulley and serves as the foundation for serpentine belt-driven accessory systems.

Key Features:

  • CNC-machined from 6061-T6 billet aluminum for exceptional strength and durability
  • Black anodized finish provides corrosion resistance and a clean, professional appearance
  • Engineered for 1985-1987 Chevy small block V8 engines (305ci and 350ci)
  • Precision-balanced construction reduces vibration and extends component life
  • Direct replacement for factory pulley in March Performance serpentine drive systems
  • Lightweight design reduces rotational mass compared to stock cast iron pulleys

March Performance pulley assemblies are designed to work seamlessly with their complete serpentine accessory drive systems, providing reliable power transfer to alternators, water pumps, power steering pumps, and air conditioning compressors. The 4021-08 is an essential component for upgrading older TPI (Tuned Port Injection) equipped engines or custom engine builds requiring modern accessory drives.
