APE Cylinder Head Studs and Nuts
for the GSXR750, GSXR 1000, Hayabusa and ZX14
Heavy duty cylinder studs are necessary to prevent head gasket leakage in high compression, nitrous, and turbocharged engines. Stock studs are made from poor material that will stretch and allow gasket leakage.
APE studs are made from heat treated chrome moly, centerless ground, and have rolled threads after heat treat for maximum strength.
APE originated heavy duty studs for performance motorcycles and today is recognized as the industry's leading manufacturer. They supply studs to all of the top engine builders.
These are priced with the cylinder head studs and nuts together.
