Finally, Bushed rods feature bushings at each end instead of a solid beam. Each connecting rod type has advantages and disadvantages that should be considered before buying.


You’ll want to pay close attention to the H-Beam design of these components – it’s vital for their performance.

The H-Beam design offers several advantages over other types of connecting rod designs, including:

  • Materials selection: choosing the suitable material for your application is essential for success.
  •  Heat treatment: heat treating the materials helps ensure strength and durability.
  •  Weight reduction: reducing weight while maintaining stability is essential in performance engines.
  •  Machining process: machining processes used on the connecting rods must be precise and accurate to provide a good fit.

The H-Beam design also allows better stress distribution throughout the connecting rod, making it less prone to breaking or bending under heavy loads. This makes it an ideal choice for high-performance applications, such as racing engines or engine rebuilds, where power output is increased significantly from stock levels.

Additionally, its shape contributes to improved reliability due to its ability to balance out impacts more evenly across its surface area than other designs.


Exploring I-Beam designs for your components is like taking two steps forward and one step back, as the shape helps to improve reliability but is less weight-efficient than H-Beam designs. The advantages of an I-Beam design for forged connecting rods are its metal properties when subjected to stress and heat, which make it more reliable than other shapes.
