ARP 423-2001 Intake Manifold Bolt Kit Hex Head

ARP's 423-2001 intake manifold bolt kit delivers professional-grade fastening solutions engineered to prevent manifold leaks and ensure reliable gasket sealing. These precision-machined bolts feature hex heads and are constructed from high-strength materials rated at 170,000 psi tensile strength.

Key Features:

• 170,000 psi tensile strength for superior clamping force
• Precision-machined threads for optimum engagement and consistent torque loading
• Wide underhead flange design with included washers for even load distribution
• Rolled threads resist galling and thread damage during installation
• Available in black oxide chrome moly or corrosion-resistant stainless steel finishes
• Hex head configuration for standard wrench installation

Each kit includes precision washers to ensure proper load distribution across the intake manifold mating surface. The rolled thread design promotes more accurate torque readings compared to cut threads, facilitating optimal gasket compression and long-term sealing performance. Special NASCAR edition bolts feature drilled heads (one per set) to accommodate tech inspection sealing requirements.
