Designed for use on 12-volt alternators or generators. It offers reliable performance, clean aesthetics, and compatibility with stock crank pulley ratios. Key Features Versatile Fit: Works with either alternator or generator setups Chrome Finish: Polished exterior resists corrosion and enhances engine bay appearance Proper Sizing: Built to match factory belt path & pulley ratios Shim Compatibility: Supports up to 10 shims total (placement inside or outside) to fine-tune belt tension Specifications & Notes Outer Diameter: ~4.25" (108 mm) Pulley Ratio: Fan rotates ~1.64× for each crank revolution Fitment Range: Typical for VW Beetle, Super Beetle, Bus, Ghia, Type 3, Thing, and other air-cooled 12V models Installation Tip: Use all 10 shims when adjusting (shifting inside loosens the belt; shifting outside tightens it) Why Choose This Pulley? Using a well‐balanced, polished pulley like this helps maintain optimal belt tension, protects engine components, and gives your setup a cleaner, more refined look. It’s a great drop-in upgrade or replacement option for restoring or maintaining your VW’s charging and cooling systems. 9191
