Freeze Plugs - Rocker shaft - Package of 4 - New

These are the small freeze plugs that press into the ends of the rocker shafts. These are often overlooked, but we strongly recommend that during teardown or inspection, you remove the old plugs and thoroughly clean the inside of the shafts with a bottle brush before installing new plugs. Sold in a package of 4. Use one package per engine. Cheap insurance. Works with stock (factory type) shafts only. Will not work with aftermarket (thick wall) shafts.
