Engine Reliability with ARP Main Stud Kits

When you are pushing your Mitsubishi engine to its limits, factory main bolts simply aren't enough. The ARP 207-5401 Main Stud Kit is engineered to provide the clamping force necessary to prevent main cap walk and ensure bottom-end stability under extreme boost and high-RPM conditions. Manufactured from premium 8740 chromoly steel, these studs are heat-treated and precision-machined to exceed OEM specifications.

Key Features and Benefits

  • Superior Strength: Rated at 190,000 psi tensile strength for maximum durability.
  • Precision Fitment: Designed specifically for the 4G63 and related Mitsubishi engine platforms.
  • Consistent Clamping: Studs allow for more accurate torque readings and even distribution of load.
  • Complete Kit: Includes high-quality nuts and hardened parallel-ground washers.

Whether you are building a street-strip monster or a dedicated track car, these main studs are a critical upgrade for any high-horsepower build. The kit ensures that your main caps stay locked in place, protecting your crankshaft and bearings from the stresses of increased power output. This specific kit is compatible with a wide range of vehicles, including the legendary Lancer Evolution and the DSM platform (Eclipse/Talon/Laser). Trust your engine internals to the industry leader in fastener technology. For all your high-performance engine hardware needs, rely on the expert selection available at GGCRACING.
