PEC Steel | H Section Con Rod Set 146.25mm | Fiesta ST150 Duratec HE I4 G0050

PEC Steel | H Section Con Rod Set 146.25mm | Fiesta ST150 Duratec HE I4 G0050

SKU: G0050
DESCRIPTION
 
Component: PEC Performance Engine Components H-Section Steel Connecting Rod Set
Application: Ford Duratec HE I4 2.0L 16v (ST150 Fiesta, Focus, et al.)
Part Reference: G0050
Center-to-Center Length: 146.25mm
 
Design & Material Science:
Forged from Swedish-sourced AISI 4340 (EN24) aircraft-quality alloy steel, these rods utilize a proprietary H-beam section geometry. This design optimally manages inertial and compressive loads by placing material along the neutral axis for maximum stiffness-to-weight ratio, providing superior resistance to column buckling and torsional flex compared to OEM designs.
 
The forging is subjected to a precise heat treatment cycle to achieve a core hardness of HRC 35-38, followed by a shot-peening process. This induces beneficial compressive stresses on the rod's surface, dramatically increasing its fatigue life and resistance to crack propagation under cyclic high-RPM loading.
 
Critical Dimensions & Machining:
  • Small End: 18.00mm bore, bushed with a precision bronze lining to support a fully floating piston pin. Width: 21.80mm.
  • Big End: 50.00mm bore, machined to exacting tolerances for perfect bearing crush and oil clearance. Width: 21.80mm.
  • Fastening System: Utilizes ARP 2000-series 3/8" cap screws as standard, engineered for a clamping load sufficient for power targets up to approximately 900hp (225hp/cylinder) in a balanced four-cylinder application. For extreme-duty use cases involving sustained high RPM (e.g., competition drifting) or severe instantaneous torque shock (e.g., drag racing with aggressive launch control), an upgrade to ARP Custom Age 625+ fasteners is recommended. This alloy upgrade increases the clamp force retention, raising the recommended safe operational ceiling to ~250hp per cylinder and extending the RPM resilience.
 
Performance Calibration & Validation:
Each rod set is the product of PEC's in-house design and validation pipeline, honed over a decade of specialized development. The components are not merely manufactured but engineered as a system—the synergy between the Swedish forging, H-beam topology, controlled heat treatment, and selectable fastener grades allows for precise performance calibration. The stated 8,500 RPM (standard bolts) and 9,000 RPM (upgraded bolts) safe limits are derived from this systems-engineering approach, providing engine builders with a deterministic, rather than anecdotal, foundation for high-output and high-revving Duratec builds.
 
Value Proposition:
PEC rods represent a calculated performance synthesis, bridging the gap between cost-efficient accessibility and motorsport-grade reliability. They solve the fundamental "weak link" equation in the stressed Duratec engine by offering a drop-in, dimensionally exact component that transforms the rotating assembly into a platform capable of supporting significant power multiplication and rotational velocity, backed by a proven legacy in competitive environments.
