Building or rebuilding a Honda B16A/VTEC engine? You'll want these ARP Main Studs in your toolkit. This kit (part #208-5402) is made right here in the USA from premium 8740 alloy steel, heat-treated to a super strong 200,000 psi. That means these studs can handle serious stress and torque without stretching or failing. ARP doesn't cut corners – they centerless grind each stud after heat treatment to make sure it's perfectly straight, and they roll the threads afterwards for way better fatigue strength (like 1000% better than cheaper studs threaded before heating). This kit fits Honda B16A2, B16A3, and JDM B16A engines. A quick heads-up: after installing these, you might need to line hone the main journals for a perfect fit, but that's pretty standard for performance builds. These studs are all about reliability and precision, giving your engine block that extra clamping force and stability. If you're aiming for a stout, reliable build whether it's for track days or a street machine, these ARP studs are a solid investment. Trust the pros who've been doing this for years – your engine will thank you!
