The I-Beam Connecting rods for Mini Cooper S R53 are manufactured from 4340 high tensile steel, they are designed for high performance, extreme durability and extra rigidity. The bushings made from AMPCO 18 material for excellent resistance to wear and fatigue and have a radial groove for the oil reservoir. They are shot peened to relieve stress from the material and multi-stage heat-treated to increase rigidity. The tight tolerances in the production process, ensure a perfect fitment while optimizing the oil clearances. Bend and twist are tightly controlled.

 

Each rod includes ARP 2000 cap fasteners that are rated at 220,00 psi, optional ARP L19 material available as an upgrade. The Connecting rod kit supplied with ARP moly and full fitting instructions.

 

Additional machining processes

  • Dowel sleeves for perfect fit and accurate re-assembling
  • Lipped Cap Relief for improved big-end integrity at extreme applications
  • Grooves in Thrust Face for weight reduction
