Product Description
Studs are the preferred fastener choice for high performance engines. Unlike a bolt, a stud uses all of the threads in the case, and it doesn't have to be removed during disassembly which adds wear on the case threads. Studs don't twist like bolts when being torqued down, so torque readings are more accurate.
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 and 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.
*Note - Comes with Head Nuts

Add Washers!
Using these on 2014 ZX14R. The studs and nuts are great quality. HOWEVER, the OD of the nuts is SMALLER than the OD of the washers on the stock bolts. You can't reuse the stock washers because the bolts have rolled threads and the washers won't come off. The end result is that the bearing surface of the nuts is SMALLER than stock unless you add washers. My friend built without the washers and blew a head gasket straight out of the box. The kit really should have a different nut design or have washers included. The stock (non reusable) washers have a 20mm OD and 10MM ID.
