MED ROCKER POST SHIM SET
A set of rocker post shims to perfect the rocker geometry setup on standard forged or MED roller rockers.
These can be useful on engine builds where the head or block face has been skimmed to the point of affecting the valve lift.
As a general rule, it's best to lift the rocker posts by the same amount machined from the head/block face, but some experimentation may be required.
Available as 0.5mm, 1mm and 1.5mm thick, with four in a pack.
