Construction & Design

These connecting rods are forged from premium steel, offering a significant upgrade over stock components in terms of strength and durability. The forging process ensures a uniform grain structure, which enhances fatigue resistance and overall robustness. The rods feature a lightweight yet strong design, optimized through computer-aided engineering (CAE) to reduce reciprocating mass and improve engine response.

The ARP Custom Age 625+ fasteners are specially heat-treated and designed for high-performance applications, providing increased clamp load and resistance to loosening under extreme conditions. The rods are precision-machined to tight tolerances, ensuring perfect alignment and balance, which translates into smoother engine operation and reduced vibrations. The design incorporates a compact, high-strength beam profile that maintains integrity during high-stress scenarios, such as forced induction or high RPM racing.

Installation & Fitment

The Brian Crower CONNECTING RODS are designed as direct replacements for the factory rods in the Mitsubishi 4B11T engine. Installation requires standard engine assembly procedures, including proper torque specifications for the ARP fasteners. No additional modifications or machining are typically necessary, but it is recommended to have a professional machine shop or engine builder handle the assembly to ensure optimal results. Proper torqueing and assembly procedures are essential for maximum performance and longevity.

• Direct bolt-in replacement for factory rods.
• Requires standard engine assembly tools and techniques.
• No cutting or major modifications needed.
