HEAVY DUTY HEAT TREATED CYLINDER STUDS
Heavy duty cylinder studs are necessary to prevent head gasket leakage in high compression 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. We supply studs to all of the top engine builders

No matter whose parts you have in your engine, join the top names in racing and insist on APE studs to hold it all together.
