Callies Ultra Rods

Callies Ultra Rods

Every Ultra rod is produced from Extremely clean Timken steel that is produced to our exact requirements.  This proprietary steel is then forged in Trenton, Michigan, before being brought into our Ohio facility for machining.   Each step of the manufacturing history of every Ultra rod is meticulously maintained by these fine American manufacturers.  You can be confident in the material and workmanship of these fine components.

Industry leading features include:

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.
