Construction & Design

The Brian Crower Sportsman connecting rods are meticulously crafted from aerospace-grade 4340 chromoly steel, known for its exceptional strength-to-weight ratio and fatigue life. The CNC machining process guarantees tight tolerances and a smooth surface finish, which reduces friction and enhances overall engine efficiency. The rods feature a proven I-beam design that balances strength and weight, optimizing the engine's ability to handle high power levels without sacrificing reliability. The inclusion of high-quality pin bushings made from Aluminum, Silicone, and Bronze ensures smooth piston movement and minimizes wear over time. These rods are finished with a micropolished surface treatment, further reducing friction and heat buildup during operation. Designed for easy installation, they are compatible with stock or upgraded pistons and are suitable for engines subjected to high boost pressures, aggressive tuning, and extended high-RPM use.

Installation & Fitment

The Brian Crower Sportsman connecting rods are designed as direct replacements for the factory rods in Mitsubishi 4G63 engines found in Eclipse, Talon, and Evolution models from 1992 to 2006. Installation is straightforward for experienced engine builders and requires standard machining clearances and proper torque specifications. These rods are compatible with OEM or aftermarket pistons and crankshafts, and no additional modifications are typically necessary. Due to their high-quality construction and precise fitment, they provide a reliable upgrade for engines subjected to high boost, high RPM, or forced induction applications. Always ensure proper assembly procedures and torque specifications are followed to maximize performance and longevity.
