ARP 2AZFE Main Stud Kit for Toyota 2.4L Engines

When you are pushing your Toyota 2.4L 2AZFE engine to its limits, factory main bolts simply cannot provide the consistent clamping force required for high-performance applications. The ARP 2AZFE Main Stud Kit is engineered to provide superior structural integrity, preventing main cap walk and ensuring your crankshaft remains perfectly aligned under extreme load.

Technical Specifications & Benefits

• Material: Forged 8740 chromoly steel for maximum tensile strength.
• Clamping Force: Significantly higher than OEM hardware to prevent main cap movement.
• Precision Fitment: Designed specifically for the 2AZFE engine block geometry.
• Kit Includes: High-quality studs, hardened parallel-ground washers, and premium nuts.
• Heat Treated: Precision heat-treated for long-term durability and fatigue resistance.

This kit is essential for anyone performing a high-compression build, turbocharging, or race-spec engine overhaul on vehicles including the Scion tC, Toyota Camry, RAV4, and Highlander. By replacing the stock bolts with these professional-grade studs, you eliminate the risk of fastener stretch, which is a common failure point in high-output 2AZFE engines. Whether you are building a daily driver with a bit more power or a track-ready machine, these studs provide the peace of mind that your bottom end is secure.
