How many connecting rods do I need for my engine?

Connecting rods are typically sold individually, but you will need a full set for your engine. Most 4-cylinder engines require four connecting rods. Always confirm the exact number needed for your specific engine build.

What is the benefit of a 6mm longer connecting rod?

A longer connecting rod can alter the piston's stroke and rod angle, which can affect engine characteristics like torque output and piston speed. This is often used in custom engine builds to achieve specific performance goals.

What is the difference between 4340 steel and other materials?

Forged 4340 steel is a strong and well-known material for performance connecting rods. It offers a good balance of strength, toughness, and fatigue resistance, making it suitable for engines that produce more power than stock.

About this part

Product Details

If you're rebuilding the engine in your 1993-1999 Mitsubishi Eclipse, Eagle Talon, Plymouth Laser, or 2003-2006 Mitsubishi Lancer, these Manley Pro Series I-Beam connecting rods are a solid option. They are specifically designed for the 4G63T engine and are 6mm longer than stock, which can be useful for certain engine builds. Manley is known for making well-built internal engine components, and these rods are no exception.

These connecting rods are forged from 4340 steel, a strong material commonly used for performance engine parts because it can handle the stresses of higher horsepower and RPMs. They also come with 625+ bolts, which are a step up from standard hardware and offer improved clamping force. While these are sold individually, most engine builds will require a full set to ensure balanced rotating assembly performance.
