ARP has engineered and produced bespoke K Series flywheel bolts for all aftermarket and OEM cranks. After months of thorough testing and R&D, the finished product is the correct length, thickness, and diameter to fit these crankshafts in both street and track applications. 

ARP exclusively produces these with the same high-quality process that has made them the world leader in fasteners. Every set of bolts come included with TQ instructions and ft/lbs specification for proper installation. Always make sure you go in a criss-cross pattern when flywheel bolts are torqued down. Make sure you have an up to date torque wrench. Torque wrench calibration will lose its accuracy over time. 

Made in the USA.
