$39.25

Mfr part # 234-2503 · Livernois SKU ARP234-2503 · Pulleys & Accessory Drive

Description

As the crankshaft flexes and twists, the balancer absorbs incredible amounts of kinetic energy. To ensure that the balancer is locked in position, ARP has developed these ultra strong 200,000 psi bolts that let you exert maximum clamping force. Special features include 1/4˝ thick, wide area washer and an extra tall 12-point head that accepts a deep socket and eliminates the worry of stripping the head.

NOTE: Does not fit vehicles with Dry Sump oiling systems
