• H-Beam design provides an ideal balance of strength and weight, enhancing engine reliability under high-stress conditions.
• 24mm wrist pin diameter for increased pin stability and reduced deflection.
• 6.2-inch center-to-center length, optimized for Chrysler 5.7L, 6.1L, and 6.4L HEMI engines.
• Machined with precision to meet tight tolerances, ensuring consistent fitment and performance.
• Includes ARP 2000 fasteners, known for their exceptional clamping force and durability.
• Designed to meet the same rigorous quality standards as Manley’s Sportsmaster and Pro Series rods.
• Ideal for naturally aspirated and forced induction applications alike.

Construction & Design:

Manley’s H-Beam connecting rods are forged from premium-grade steel, delivering a robust structure capable of withstanding the rigors of high-performance use. The H-Beam configuration enhances rigidity while minimizing weight, which helps reduce rotating mass and improve engine response. Each rod is precision-machined to exact specifications, ensuring consistent bore alignment and smooth operation.

The inclusion of ARP 2000 bolts provides superior tensile strength and fatigue resistance, critical for maintaining rod integrity under extreme loads. This combination of materials and craftsmanship results in a connecting rod set that supports both reliability and performance for your Chrysler HEMI engine build.

Installation & Fitment:

This set of eight connecting rods is designed as a direct replacement for factory rods in Chrysler 5.7L, 6.1L, and 6.4L HEMI engines. They fit OEM specifications and utilize standard wrist pin sizes, making installation straightforward for experienced engine builders and professional shops.

No modifications to the engine block or crankshaft are required when installing these rods. Proper balancing and assembly practices are recommended to ensure optimal engine performance and longevity.
