Carrillo Mitsubishi 4G63 1st Gen Pro-H 3/8 CARR Bolt Connecting Rods

If you're building a high-performance Mitsubishi 4G63 engine for your 1990-1992 Eagle Talon, Plymouth Laser, or Mitsubishi Eclipse, these Carrillo Pro-H connecting rods are a solid choice. Carrillo has a long-standing reputation for making strong, reliable internal engine components, and these rods are built to handle the demands of a performance build. They use their well-known Pro-H beam design, which is a strong I-beam shape that’s been refined over years of racing and high-performance applications. This design offers a great balance of strength and weight, which is crucial for engine longevity and power delivery.

These rods are specifically designed for the 4G63 engine, ensuring a direct fitment for the first generation of these popular DSM (Diamond-Star Motors) platforms. They come equipped with 3/8 inch CARR bolts, which are Carrillo's own high-strength fasteners designed to securely hold the rod cap under extreme cylinder pressures and rotational forces. The material used is a high-grade forged alloy steel, heat-treated for maximum strength and durability. This means they can withstand the increased stress from higher horsepower, boosted applications, and aggressive driving without flexing or failing. The precision machining ensures that each rod is identical, which is vital for proper engine balance and smooth operation.

When you're investing in an engine build, using well-made internal components like these Carrillo rods is essential for achieving your performance goals and ensuring the engine lasts. They are a popular choice for enthusiasts looking to push the limits of their 4G63 engine. Make sure you have the correct pistons and crankshaft for your build, as these rods are designed to work with specific combinations. Always refer to the manufacturer's installation instructions for proper torque specifications and any specific assembly requirements.
