Cylinder sleeve shims are used to precisely adjust the height of a cylinder sleeve within an engine block, ensuring proper alignment and sealing with the cylinder head, preventing leaks, and maintaining optimal compression by creating the correct gap between the sleeve and the head gasket; essentially, they act as spacers to fine-tune the critical dimensions of the cylinder assembly.

Innovative Machine & Supply manufactures cylinder sleeve shims for many common applications. The shims are laser cut from 304 Stainless Steel for hardness and durability. We can make them for any application as long as we are given ID and OD specs.

Precise fit: Shims allow for minute adjustments to achieve the ideal sleeve protrusion, which is crucial for a good seal with the head gasket.

• Preventing leaks: Incorrect sleeve height can lead to coolant leaks past the cylinder head gasket, which shims help mitigate.·

• Maintaining compression: Proper sleeve height is vital for maintaining consistent compression within the cylinder.

• Different thicknesses: Shims come in various thicknesses to accommodate different engine configurations and repair needs.
