Reinforce Your FA20 Bottom End

The ARP FA20 Main Bolt Kit (Part #260-5001) is a critical upgrade for any Subaru 2.0L FA20 engine build. As you increase power output, the factory main bolts can become a weak link, leading to main bearing cap movement and potential catastrophic engine failure. ARP’s main bolt kit provides the necessary clamping force to keep your crankshaft secure under high-load conditions.

Engineered for Performance

• Increased Clamping: Significantly stronger than OEM bolts, ensuring the main bearing caps remain stationary.
• 8740 Chromoly: Forged from high-quality 8740 chromoly steel for maximum durability and fatigue resistance.
• Precision Machined: Threads are rolled after heat treatment to ensure excellent fatigue strength and consistent torque values.
• Reliability: Reduces the risk of main bearing fretting and cap walk in high-horsepower applications.

Designed specifically for the FA20 platform, this kit is an essential component for any performance engine build. Whether you are upgrading your internals for a larger turbo or simply want to ensure your engine is built to last, these main bolts provide the strength and stability required. By replacing the stock hardware with ARP, you are investing in the long-term health of your engine. Proper installation ensures that your crankshaft is supported correctly, allowing for smoother operation and increased reliability under stress. Build your engine with confidence using the best hardware available. For all your high-performance automotive needs, trust GGCRACING.
