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 engin 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.

HEAVY DUTY CYLINDER HEAD NUTS

CYLINDER HEAD NUTS

Super heat treated cylinder head nuts are a must for high output engines.
Help prevent blown and leaking head gaskets caused by the threads in the soft stock nuts stretching. APE nuts are machined from alloy steel and fully heat treated for maximum strength. Nuts are .150" taller than stock to prevent the nut from bottoming out on the stud when the head has been milled.

ALL GENUINE APE NUTS HAVE "APE" STAMPED ON TOP (if they have a top).....BEWARE OF IMITATIONS.
Packed in complete engine sets.
