D-Series Engine Fastener Kit

The ARP Pro Series head stud kit (208-4301) is engineered to provide superior clamping force and reliability for Honda D-series engines. Each stud is crafted from 8740 chromoly and undergoes a cold-forging process to ensure molecular integrity, followed by heat treatment prior to thread rolling and machining. This meticulous process results in studs with a tensile strength of 200,000 psi, offering a significant upgrade over stock head bolts. This kit features 12-point nuts for easy installation and removal, and includes hardened parallel washers. These washers are crucial for achieving an even load distribution across the cylinder head, which directly contributes to accurate torque readings and a secure engine assembly. The black oxide finish on the fasteners adds a layer of corrosion resistance. The ARP 208-4301 head stud kit is designed for numerous Honda applications, including various models of the Acura Integra, Honda Civic, CRX, and Del Sol spanning from the late 1980s through to the early 2000s, specifically for D13, D14, D15, D16, and some D17 engines. It is also listed for various Rover models in European and other markets. Please consult the detailed application list to confirm fitment for your specific vehicle year, engine code, and market. The kit contains 10 studs.
