Product Description
LOCK DOWN YOUR DAMPER — INSTALL CONFIDENCE. The ARP 150-2505 Balancer Bolt Kit is purpose-built for 2003–2010 Ford 6.0L & 6.4L Powerstroke engines. ARP’s Pro Series chromoly hardware and parallel-ground washers provide repeatable clamp load and secure harmonic damper retention under towing, work, and performance use. A compact 12-point head (3/4" socket) eases service in tight engine bays, and the correct M12 x 1.25 thread with ~2.425" underhead length matches OE geometry for proper engagement.
Built for durability, finished in black oxide, and supplied with washers, this kit is a smart upgrade whenever the damper is serviced or replaced. Pair it with ARP head studs and main hardware for a bulletproof fastener system across your Powerstroke build.
