The ARP Dodge Cummins Balancer Bolt Kits are optimized for enhanced reliability and increased strength. Each ARP balancer bolt kit includes four (M12 x 1.25) 8740 Pro Series balancer bolts that are rated at 200,000 psi tensile strength, four 8740 parallel ground washers and a 1/2 oz. pack of ARP Ultra-Torque fastener assembly lubricant. ARP bolts are cold forged to ensure molecular integrity, heat treated prior to thread rolling and machining and designed to exceed the OEM fasteners in strength and durability. Optimum design, enhanced reliability and increased strength are the main attributes of ARP's Pro Series balancer bolt kits.
