Callies CAU14138 Ultra-Light Weight Forged I-Beam Conrod Set 6.000" Chev SB

Item Description

Ultra connecting rods are made entirely in the U.S.A. Every Ultra connecting rod is produced from specially formulated Timken 4330M steel. This material is then precision forged in Michigan and fully machined in the Callies Fostoria, Ohio production 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.
