Fits Subaru EJ205 and EJ257 engines.

Manley Turbo Tuff Pro Series I-Beam connecting rods are engineered to handle the extreme cylinder pressures and high RPMs found in built Subaru engines. These rods are manufactured from forged 4340 vacuum degassed steel, a process that removes impurities to ensure maximum material density and structural integrity. The I-beam configuration provides superior resistance to bending and compressive loads compared to standard H-beam designs, making them the preferred choice for high-boost applications.

This set includes premium ARP 625+ bolts. These fasteners offer significantly higher tensile strength than standard ARP2000 hardware, providing the critical clamping force necessary to maintain big-end roundness and bearing clearance under severe rotational stress.

  • Center-to-Center Length: 5.216 in
  • Material: Forged 4340 vacuum degassed alloy
  • Beam Style: Turbo Tuff I-Beam
  • Fasteners: Upgraded ARP 625+ bolts included
  • NHRA Legal for select Stock and Super Stock classes
