Magluv ALL31066 Crankshaft Pulley Shim Kit

The Magluv ALL31066 Crankshaft Pulley Shim Kit is designed to replace or upgrade a crank pulley spacer for Chevy engines. It is built as a reliable option to Allstar Performance crank pulley spacers, tailored for small-block Chevy foundations and their big-block counterparts. The kit includes three aluminum shims, each with a different thickness, to help you align the pulley with greater precision and ease. In the engine bay, where space is tight and tolerances matter, this set offers a simple path to a more consistent pulley relationship without sacrificing serviceability.

Crafted for durability and dependable fit, these shims are made from high quality aluminum and finished to resist corrosion. The outside diameter is 4 inches while the inside diameter is 1.25 inches, providing a generous sweep that works with a variety of pulley styles and water pump configurations. The thickness options are 1.12 inches (3 mm), 0.08 inches (2.07 mm), and 0.06 inches (1.56 mm), giving you a versatile toolbox to dial in the spacing your engine needs.

What you get

  • Three aluminum shims offering three distinct thicknesses for precise alignment
  • 4 inch outer diameter and 1.25 inch inner diameter suitable for common pulleys
  • Durable aluminum construction with corrosion resistance for long term use
  • Dual bolt hole pattern water pump compatibility to fit GM and Ford pumps
