Upgrade or fine-tune the drive on Ford and GM water pumps with the Allstar Performance Water Pump Pulley Shim set. This trio of aluminum shims provides small, deliberate adjustments to pulley alignment, helping you dial in belt alignment and spacing without swapping the whole assembly. The shims come in two thickness options, 0.063in and 0.125in, and fit both 5/8in and 3/4in shaft diameters. The natural aluminum finish keeps things lightweight and durable in challenging environments, and the set is designed for vehicle-specific fit, making it a practical choice for maintenance or minor tuning.

What makes this shim set practical

  • Three aluminum shims included, offering flexible spacing options for precise pulley alignment.
  • Two thickness options (0.063in and 0.125in) to accommodate different shaft diameters and belt layouts.
  • Compatibility with Ford and GM water pumps helps cover common vehicle models.
  • Natural aluminum finish provides corrosion resistance and durability without adding unnecessary weight.
  • Vehicle-specific fit type indicates the shims are intended for use with particular pump configurations.

The set is built for real-world use, whether you are swapping a pump, adjusting a belt drive, or refining timing belt alignment during routine service. The lightweight aluminum design makes handling straightforward, and the modest set weight helps keep the overall assembly balanced during installation.

How to use

1) Remove the existing pulley and inspect the pump interface. 2) Select the appropriate shim thickness based on your measurement or alignment need. 3) Place the shim between the pulley and the mounting surface, then secure with standard hardware. 4) Recheck belt alignment and tension, and test with the engine off before running.
