APE Main Studs for Hayabusa

For the Suzuki Hayabusa, heat treated chrome moly main bearing studs. These studs feature rolled threads, centerless ground surfaces, and come with competition style twelve point flange nuts.
As racing's leading supplier of heavy duty engine stud kits, APE already has their very popular top end cylinder studs for the big Suzuki, and now turned their attention to the bottom end. By replacing the bottom end bolts with heavy duty studs, it helps minimize the chances of high output engines trying to separate the engine cases at the crank center line resulting in oil pressure loss and possible engine bearing failure.

Hot rodders have already pushed the power of these engines to over twice what the factory intended. As with all engines with this power output, heavy duty fasteners are mandatory to hold them together.

APE is the leading manufacturer of heavy duty cylinder studs for motorcycles. The Hayabusa studs are made from ultra high heat treated premium 8740 steel and feature rolled threads for maximum strength. Torque to 60 lbs. APE head nuts are machined from billet stock and heat treated to prevent threads from stretching. This set up is a must for all serious go fast motors. Extra thread on the nut end allows them to also be used with no plate when using APE CHN10125-10 cylinder head nuts.

Please note that the cylinder head can not be removed with engine bolted in place when using studs.
