ARP 134-3701 High Performance Cylinder Head Bolts for Chevy Small Block

ARP 134-3701 High Performance Series cylinder head bolts provide a premium upgrade over factory fasteners for select Chevrolet small block applications. Engineered for 23 degree cast iron OEM heads, Gen III Vortec/Truck applications, and most Edelbrock LT-AFR, Brodix -8, -10, -11, -11xb, LT-1, Pro-1, and Trick Flow cylinder heads, these bolts deliver superior clamping force and reliability for demanding engine builds.

Key Features:

• 180,000 psi tensile strength—15% stronger than Grade 8 hardware for maximum clamping force
• Compact 12-point head design for easy installation in tight spaces
• Wide area flanged head eliminates valve train removal for cylinder head retorquing
• Includes hardened parallel-ground washers for even load distribution
• Manufactured in-house with strict quality control for zero-defect reliability

ARP fasteners are precision-manufactured using proprietary materials and heat treatment processes to ensure consistent performance under extreme conditions. Each bolt is designed to provide the secure cylinder head retention critical for high-performance and racing applications while simplifying maintenance procedures.
