ARP GM LS with Adapter Plate Flexplate Bolt Kit

This kit includes a set of six 8740 Pro Series flexplate bolts that are rated at 200,000 psi and a 1/2 oz. pack of ARP Ultra-Torque fastener assembly lubricant. This kit replaces GM Performance bolt part no# 19257940 and should be used in conjunction with GM Performance part no# 12021399 crankshaft spacer kit. 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 Pro Series flexplate bolts.
