CALLIES ULTRA CONNECTING RODS

 

 

Ultra connecting rods are made entirely in the U.S.A. Every Ultra connecting rod is produced from specially formulated Timken
4330V steel. This material is then precision forged in Michigan and fully machined in our Fostoria, Ohio facility. Many geometric
nuances have been incorporated into the design of Ultra connecting rods. These design features enhance the Ultra against
specific loads and stresses which are applied to connecting rods subjected to high load, high RPM applications. Ultra connecting
rods are fastened by high alloy cap screws made specifically for severe duty service by ARP Inc. Produced with rolled threads,
these unique bolts offer improved thread engagement for a smoother more consistent net clamping load. To eliminate
deformation and extrusion only AMS 642 bronze alloy is used within the wrist pin housing bore.
