ARP 154-2004 Intake Manifold Bolt Kit Hex Head Chrome Moly

ARP's 154-2004 intake manifold bolt kit delivers superior clamping force and reliability to prevent manifold leaks and ensure optimal gasket sealing. Engineered for high-performance applications, these premium fasteners are manufactured from chrome moly steel with a black oxide finish for corrosion resistance.

Key Features:

• 170,000 psi tensile strength rating for exceptional clamping force
• Precision-machined threads for optimum engagement and consistent torque loading
• Hex head design with wide underhead flange for even load distribution
• Rolled threads prevent galling and thread damage during installation
• Includes companion washers for proper load distribution across gasket surfaces
• Black oxide finish on chrome moly steel construction

ARP fasteners are precision-manufactured to aerospace tolerances, ensuring reliable performance in demanding engine applications. The wide flange head design and included washers work together to distribute clamping loads evenly across the intake manifold mounting surface, promoting superior gasket sealing and preventing vacuum leaks. Rolled threads provide smoother torque characteristics compared to cut threads, allowing for more accurate torque specifications and reduced risk of thread galling.

Note: Special NASCAR-spec versions of ARP intake bolts feature drilled heads (one per set) to accommodate tech inspection seals and utilize 12-point heads with generous flanges.
