U15115 - 6.750 Rod Length - 2.200 Crank Pin

Callies Ultra connecting rods are produced from extremely clean Timken steel that is formulated to our exact specifications.  This proprietary steel is forged in Trenton, Michigan, and manufactured 100% in our Fostoria, Ohio facility.  

  • Increased Stroker Clearance for long stoke applications
  • Strengthening Gussets have been added around the cap screws to reduce this highly stressed area.
  • 100% Thread engagement assures no bolt threads are left exposed in the area between the bolt thread and shank.
  • Specifically designed, 260Ksi Ultra Bolts with rolled threads are installed to provide improved engagement for a more consistent clamping load. Callies provides and recommends the use of ARP Ultra torque lube
