Product Details

Featuring a 9.550-inch center-to-center length and 7/16-inch rod bolt diameter, these rods are designed to deliver exceptional strength-to-weight performance in demanding builds.

Manley Performance is a trusted name in racing engine components, and these H-beam rods are manufactured from aircraft-grade 4130 chromoly steel — a material known for its superior tensile strength, toughness, and fatigue resistance compared to standard connecting rod steel. The .165-inch wall thickness (lightweight specification) reduces reciprocating mass while maintaining structural integrity under extreme RPM and cylinder pressure conditions.

Key Features:

  • Material: 4130 chromoly steel for superior strength and fatigue resistance
  • Center-to-Center Length: 9.550 inches
  • Rod Bolt Diameter: 7/16 inch
  • Wall Thickness: .165" lightweight specification
  • Construction: H-beam design for optimized strength-to-weight ratio
  • Designed for high-performance street and competition racing applications
  • Precision machined for consistent weight and dimensional tolerances

Manley 4130 chromoly connecting rods are a popular upgrade for engine builders seeking a durable, race-proven alternative to OEM rods. These rods are well-suited for forced induction, nitrous, and naturally aspirated high-RPM builds where stock connecting rods would be a limiting factor.

Quick and easy. Just hope it fits my car.

Great price and good company to buy from!

I ordered CV axles from Autoplicity and had them in less than a week! Definitely the best prices for quality product on this item. Will be a return customer for sure!

I was apprehensiveness at first to make a major purchase with Autoplicity due to their extremely low price and lack of reviews. I decided to take the chance and I am very glad I did. I made my order on a Monday morning at 0900 eastern time and my product arrived on Wednesday at 3pm. The item was exactly as described and the most astonishing part is that my purchase was released from the factory less than 45 days ago. I was expecting a model that had been sitting on a shelf for the last year and needed to be updated. That was not the case. I will definitely order from Autoplicity again in the future.

Very good price. Super quick delivery. Will def. buy from them again. Highley recomend them

great stuff cheap price. fast shipping

Sweetest price on this K&N Filter anywhere! Shipped within 24hrs too. I'm coming back to shop for my car next.
