APE Clutch Spring Kits For Motorcycle
American Performance Engineering Cylinder Studs offer higher strength than conventional bolts. 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.
