Carrillo Mitsubishi 4G63 1st Gen Pro-SA 3/8 WMC Bolt Connecting Rods

If you're building a high-performance Mitsubishi 4G63 engine for your 1990-1992 Eagle Talon, 1990-1992 Mitsubishi Eclipse, or 1990-1992 Plymouth Laser, these Carrillo Pro-SA connecting rods are a solid choice. These rods are specifically designed for the demands of boosted and high-RPM 4G63 engines, offering a significant upgrade over stock components. They are built with Carrillo's renowned attention to detail and material science, ensuring reliability when you push your engine hard.

The Pro-SA series rods are forged from a proprietary steel alloy, giving them the strength needed to handle increased cylinder pressures and combustion forces common in performance builds. They come equipped with Carrillo's WMC (Weld Forged, Machined, and Cold-drawn) bolts, which are a step up from standard ARP fasteners, offering improved tensile strength and fatigue resistance. This combination of a strong rod body and robust fasteners means these rods are well-suited for forced induction setups and aggressive tuning where engine reliability is paramount. The 3/8 inch bolt size is a common specification for these applications, ensuring compatibility with many aftermarket piston and crankshaft combinations.

When installing these connecting rods, it's important to ensure proper balancing of rotating assembly components. Precision machining and strict tolerances are hallmarks of Carrillo products, meaning they fit right into your build. These rods are a critical component for anyone looking to build a durable and powerful 4G63 engine that can withstand the rigors of track use or spirited driving.
