Flexplate bolts play an important role in the performance and safety of race vehicles and street machines. That's why the fastener experts at ARP have developed special bolts that are far superior to OEM hardware. ARP Flexplate 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 Flexplate Bolts.
