CYlINDER SHIM SETS

EMPI 21-6090-0 is a set of 85.5mm Piston Barrel Shims. These shims are designed to sit between the engine case and the bottom of the piston barrel, commonly used for setting up piston deck height to achieve the desired compression ratio in Volkswagen air-cooled engines.

Key Features:
  • Material: Steel.
  • Thickness: 0.090 inches (2.25mm).
  • Compatibility: Compatible with VW Bug, Super Beetle, Karmann Ghia, Bus, Type 3, and Thing models with 85.5mm to 88mm pistons.
  • Function: Allows for adjusting deck height without machining the cylinders. It can correct for an increase in stroke and compensate when the case is surface machined.
  • Quantity: Sold in sets of 4.

These shims are an essential component for anyone looking to fine-tune their engine's compression ratio and ensure optimal performance.
