Decompression & head saver shims

Gasket Solutions can manufacture practically any shape decompression or head saver shim.

Head shims are used where excessive material has been machined off the block or head Decompression shims are generally required when a turbo charger has been fitted to a normally aspirated engine.

A range of thicknesses generally up to 3mm thick can be manufactured, thicker shims are available on application

A non-hardening sealant will need to be used when using a shim. This is generally applied between the shim and the block, with the head gasket fitted as per car manufacturers instructions. Gasket Solutions can supply sealant on request.

Note: The head gasket will need to be re-torqued after the engine has been run at normal running temperature for 1 hour approx.
