Feuling ARP Head Bolt Kit for M8 Models

• 8 Feuling ARP stainless 12-point head bolts
• Moly assembly lubricant

High-Strength OEM Replacement
Designed as a direct replacement for factory M8 head bolts while offering increased strength, durability, and performance capability.

Built for High-Performance Engines
Engineered to exceed the needs of performance Milwaukee-Eight engines, including cammed builds, big bore applications, and high-compression setups.

Stainless 12-Point Head Bolts
Features stainless 12-point head bolts with a 3.215" under-head length for premium strength, durability, and serviceability.

180,000 PSI Tensile Strength
Rated at 180,000 PSI tensile strength, making these fasteners stronger than OEM and Grade 8 fasteners.

Precision J-Form Threads
J-form threads provide optimum thread engagement, help prevent galling, and promote more consistent torque loading during installation.

Complete Motor Kit
Includes all required head bolts needed for one Milwaukee-Eight engine.

Moly Assembly Lubricant Included
Comes with moly assembly lubricant to support proper installation and accurate torque application.

Superior Clamping Force
Designed to provide the clamping strength needed for improved head sealing and reliability in demanding engine builds.
