Description

Flywheel bolt failure is a catastrophic event that can destroy transmissions, flywheels, and pressure plates in seconds. These bolts secure the flywheel to the crankshaft, making their integrity critical to your drivetrain's safety and performance—especially when pushing the 5.0L Coyote to 7,000+ RPM. ARP's engineering addresses this vulnerability with fasteners that far exceed OEM specifications.

Forged from aerospace alloy and heat-treated prior to thread rolling and machining, these ARP flywheel bolts deliver the strength needed for high-RPM operation and competition use. The exclusive flat 12-point head design features a larger-than-stock shank diameter for increased strength and improved flywheel register. The wider diameter bolt head allows for more even distribution of torque across the flywheel to reduce stress, fatigue, and prevent cracking.

The black oxide finish provides corrosion protection while maintaining the precise tolerances required for proper clamping force distribution. Each bolt features rolled threads for superior fatigue resistance compared to cut threads, and the included installation grease ensures proper torque values during assembly.

Engineered specifically for Ford Coyote 5.0L applications. This is a direct replacement for factory flywheel bolts with significantly improved strength characteristics. Made in the USA with ARP's legendary quality control standards.

Kit Includes

8 ARP flywheel bolts—M10 x 1.00 thread, 0.975-inch UHL, chromoly steel

Manufacturer's warranty against defects

[VERIFY: Sources conflict on whether part number 156-2801 is High Performance Series (180,000 psi tensile strength) or Pro Series (190,000-200,000 psi). Summit Racing and JEGS list as Pro Series, while Steeda lists as High Performance at 180,000 psi. Need to confirm actual series designation and tensile strength rating before publishing.]
