There is a wide number of connecting rods on the market today. The most considerable difference is rod’s size and material it is made from. The most common materials are steel, aluminum, and titanium.

Steel rods

The most prevalent type of connecting rods is steel rods. Because of the strength and great durability this type of rods can be used in daily driving and in endurance racing. But there is one disadvantage of steel rods – they are extremely heavy that’s why these rods increase rotating assembly’s stress and consume more power. Performance connecting rods can be made from different grades of steel. The hardness, yield strength and tensile strength of steel rods depend on its heat treatment and forging temperature. That’s why it is recommended that you purchase rods from well-known and reliable manufacturers. CP Bullet Pistons and Rods are made by famous manufacturer and are widely used by ordinary drivers and pro racers as well.

Aluminum rods

Aluminum rods have very similar characteristics to the steel rods but are lighter up to 40%. This rod’s type is used in drag racing and in high horsepower engines. Small weight of aluminum rods allows engine to gain rev faster and to reduce stress on the crankshaft and vibration. That’s why this type of rods has a great lifespan.

Aluminum Connecting Rods

Titanium rods

Titanium rods are lighter than steel ones and stronger at the same time. But these rods are much more expensive than previous types. That’s why titanium rods are most commonly used in expensive engines for endurance and drag racing.
