2003-2010 F250 & F350 ARP Harmonic Damper Bolt Kit 150-2505

Maximize Durability

While you're clearing hills in your 2003-2010 Super Duty, your crankshaft is transmitting an insane amount of kinetic energy to your harmonic balancer. That's why it's crucial to have balancer bolts that have been manufactured for toughness and designed to handle the immense pressure of a fully loaded Super Duty. To fully ensure your balancer is securely locked in place, ARP designed and manufactured these balancer bolts using aircraft quality 8740 steel that's been heat treated prior to thread-rolling for improved retention. The extra tall 12-point bolt head accepts a deep socket to avoid stripping. Designed to exceed OE standards, these balancer bolts are cold-forged to ensure molecular integrity and have been rated at 200,000 psi!

Complete Balancer Bolt Kit

ARP wants you spending less time under the hood and more time behind the wheel, which is why they've included everything you'll need to secure your balancer to your crankshaft securely and reliably. Included along with four (M12 x 1.25) 8740 Pro Series balancer bolts, you get four 8740 parallel-ground washers, and a 1/2 oz. packet of ARP's Ultra-Torque fastener!
