This kit includes a set of seven 8740 Pro Series flywheel bolts that are rated at
200,000 psi and replace the Mitsubishi factory bolt part no#1120A062.
ARP flywheel bolts feature an exclusive flat 12 point head design and a larger than stock underhead
radius for increased strength. Each bolt is centerless ground to ensure the bearing
surface is perpendicular to the threads creating equal load distribution.
Optimum design, enhanced reliability and increased strength are the main attributes of ARP’s
Pro Series flywheel bolts.
