Description
Truly superior strength is needed on this most critical of load bearing fasteners. The crankshaft sees immense kinetic energy! Both twisting and lateral loads are exerted on this one area, and to an even greater degree on belt driven supercharged cars.
OEM fasteners are one-time-use – they stretch and must be replaced, so upgrading with the Massive Speed Precision unit is a “no-brainer”. Grade 12.9 197,000 PSI tensile strength 12 point flanged bolt finished in black oxide places superior clamp only load to balancer through the use of a separate washer plate (a full 1/4″ thick!) versus the 1 piece stocker.
Fully reusable. Will not fit LS7. Crank bolt should never be used to install balancer, use of proper tool is necessary.
These are every bit as strong as the other guys, but priced right, and IN STOCK!!!
Made right here in the USA!!!
NOW INCLUDES Genuine ULTRA-TORQUE Moly Assembly Lube!!! The other guys DON’T Include it!
