Pro Series flywheel bolts from ARP give you all that you need to bolt in your flywheel with confidence. They're much stronger than OEM hardware, forged from aerospace alloy, and are heat-treated prior to thread rolling and machining. These bolts feature an exclusive, flat 12-point head design and a larger-than-stock shank diameter for increased strength and improved flywheel register.
Compatible with flywheel thicknesses from 12mm to 14mm. Ideal for most single mass flywheels for T56, R154, & W58
These bolts are not to be used with V160/V161 dual-mass flywheels!
