12-Point Harmonic Balancer Bolt Kit

The ARP 156-2501 Harmonic Balancer Bolt Kit is engineered to provide a secure and reliable connection for your engine's harmonic balancer. As the crankshaft experiences flex and absorbs considerable energy, this ARP bolt kit ensures the balancer remains firmly locked in place, preventing potential issues and maintaining engine integrity. The kit features a robust 12-point head design, which accommodates a deep socket for straightforward installation and minimizes the risk of stripping the fastener head during tightening. Constructed from high-strength 8740 chromoly material and finished with a durable black oxide coating, this balancer bolt boasts a tensile strength of 200,000 psi, making it a superior alternative to standard factory bolts. The bolt has a thread size of M12 x 1.5 and an underhead length of 1.880 inches. A washer is included with the bolt to help distribute clamping force evenly. This kit is designed for specific Ford applications, including the 4.6L and 5.4L Modular V8 engines. It fits a range of Ford models such as the Cougar (1994-1995), Crown Victoria (1992-2004), E-series (1997-2004), Expedition (1997-2004), Explorer (2002-2004), F-150 (1997-2004), F-250 (1997-2004), Grand Marquis (1992-2004), Lobo (2004), Mustang (1996-2004), and Thunderbird (1994-1997).
