Product Details

The Manley 14559R6-8 Pro Series I-Beam Connecting Rods are engineered for high-performance GM LS engine builds requiring ultimate strength and precision. These rods feature a 6.125-inch center-to-center length and come upgraded with ARP Custom Age 625+ fasteners for maximum clamping force and reliability in extreme horsepower applications.

Key Features:

  • Forged from aircraft quality 4340 vacuum degassed steel alloy for superior strength and durability
  • Fully machined I-beam design manufactured in Manley's Lakewood, NJ facility
  • Upgraded with 3/8-inch ARP Custom Age 625+ cap screws for enhanced performance over standard ARP 2000 bolts
  • Shot peened after machining to MIL spec and 100% individually magnafluxed for quality assurance
  • Weight matched to tight tolerances for optimal engine balance
  • Round big and small end bores with tightly controlled bend and twist specifications
  • Designed for high-performance street, strip, and forced induction applications

Manley Pro Series I-Beam connecting rods represent the benchmark in fully machined, billet-style high-end connecting rods for the performance industry. The R6 suffix denotes the premium ARP 625+ fastener upgrade, making these rods ideal for turbocharged, supercharged, and high-RPM naturally aspirated LS builds.
