Construction & Design:
Manley’s connecting rods are forged from premium 4340 steel, a material known for its exceptional strength-to-weight ratio and resistance to fatigue. The vacuum degassing process removes impurities, resulting in a cleaner, more consistent metal structure. The I-beam design balances strength and weight, providing rigidity where needed while minimizing overall mass to improve engine response.
Each rod undergoes shot peening, a process that introduces compressive stresses to the surface, significantly enhancing fatigue resistance. The use of ARP 2000 cap screws ensures the rods maintain clamping integrity under extreme loads. Final machining and magnaflux inspection guarantee that every rod meets stringent quality standards, making them a reliable choice for high-performance engine builds.
Installation & Fitment:
These connecting rods are designed as direct replacements for the factory rods in the 2AZ-FE engine of the specified Scion models. Installation requires standard engine disassembly and reassembly procedures, with no modifications necessary for proper fitment. Due to their precise manufacturing tolerances, these rods ensure a seamless upgrade path for enthusiasts looking to enhance engine durability and performance.
What's Included:
- Set of 4 Manley 2AZFE I-Beam Connecting Rods (Part #14419-4)
