ARP Main Stud Kit for 99–00 Civic Si & 94–97 Del Sol VTEC

Lock in your bottom end. If you’re rebuilding, boosting, or simply want long-term reliability, the ARP Main Stud Kit delivers the clamping force and consistency your Honda engine needs where it matters most: the main caps.

Why upgrade to ARP main studs?

Factory hardware can stretch, fatigue, and lose clamp load over time—especially under high RPM, higher cylinder pressures, or repeated heat cycles. ARP main studs are engineered to help reduce cap walk, maintain more accurate torque, and provide stronger, more consistent main bearing support compared to typical OEM-style fasteners.

Built for performance. Trusted for reliability.

ARP was the first company to design and engineer fasteners specifically for racing, and they continue to lead the industry with proprietary manufacturing processes and rigorous quality control. Their manufacturing operations are ISO 9001 and AS9100 registered—standards trusted in demanding industries where failure isn’t an option.

Ideal for:

• Engine rebuilds where you want confidence in your bottom end
• Turbo/supercharged setups needing higher clamp load stability
• High-RPM VTEC builds where consistent fastener performance matters
• Track or spirited street cars that see repeated heat cycles

Fitment

• 1999–2000 Honda Civic Si

Upgrade once. Build with confidence. Add the ARP Main Stud Kit to your build and protect the investment you’re putting into your engine.
