PULLEY, ALT/ GEN CHROME 12V

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.
