Callies Connecting Rods

Callies is pleased to introduce the Ultra XD connecting rod. This unique patent pending configuration is designed for additional cam to rod clearance in long stroke Small Block Chevy racing engines. In most cases, the XD rod will provide approximately .050″ more cam clearance than our conventional Ultras, and substantially more over many of our competitor’s rods.

  • Increased Stroker Clearance – The best bolt to block & rod to cam clearance in the industry for long stoke applications.
  • Bolt Spotface Gussets – Allow optimized bolt location without loss of strength or deformation of the big end bore.
  • 100% Thread Engagement – Assures no bolt threads are left exposed in the area between the bolt thread and  shank.
  • Specifically Designed, 260Ksi Ultra Bolts – All Ultra bolts are designed to fit each specific rod. Rolled threads are employed to provide improved engagement for a more consistent clamping load.
