Ensure Harmonic Balancer Security with ARP for Your Mitsubishi 4G63

The harmonic balancer plays a critical role in mitigating crankshaft vibrations and ensuring smooth engine operation, especially in high-performance Mitsubishi 4G63 engines. The Auto Racing Products (ARP) 207-2501 Harmonic Balancer Bolt is specifically designed to provide superior clamping force and reliability, preventing balancer wobble or detachment under extreme RPMs and power outputs. This single, robust bolt is an essential upgrade for any 4G63 build, from street performance to full-blown racing applications.

Engineered for Extreme Durability and Precision

This ARP harmonic balancer bolt is meticulously crafted from high-strength chromoly steel, a material chosen for its exceptional tensile strength and fatigue resistance. It features a precise 14 mm x 1.50 thread and a length of 1.525 inches, ensuring a perfect fit and optimal engagement. The 19 mm 12-point head allows for confident torque application, minimizing the risk of rounding and ensuring a secure installation. A durable black oxide finish provides excellent corrosion resistance, protecting the bolt from the harsh engine environment.

Key Features for Mitsubishi 4G63 Engines:

• Material: High-strength Chromoly Steel for ultimate reliability.
• Finish: Black Oxide coating for superior corrosion protection.
• Thread Size: 14 mm x 1.50 thread pitch.
• Length: 1.525 inches for optimal engagement.
• Head Style: 19 mm 12-Point head for secure tightening.
• Application: Specifically designed for Mitsubishi 4G63 engines.
• Performance: Prevents harmonic balancer loosening under high stress.

The Importance of a High-Quality Balancer Bolt

The harmonic balancer is subjected to constant torsional forces and vibrations. An inferior or fatigued balancer bolt can lead to the balancer loosening, causing severe engine damage, including crankshaft wear and accessory drive issues. Upgrading to an ARP chromoly balancer bolt provides the peace of mind that your critical engine components are securely fastened. This is a small but vital investment that protects your entire engine assembly, allowing your Mitsubishi 4G63 to perform reliably at its peak, whether on the street, strip, or track.

Fitment:

• Mitsubishi 4G63 engines (found in various Lancer Evolution, Eclipse, Talon, and Galant VR-4 models)
• Specific Mitsubishi applications requiring a 14mm x 1.50 harmonic balancer bolt.
