H-Beam 4340 Steel Connecting Rod 6.125

Probe Industries H-Beam Steel Rods are precision forged of select 4340 aircraft quality steel, vacuum degassed to remove impurities. Probe Industries rods are forged in two pieces to insure proper grain flow. All surfaces are then CNC machined into our track proven H-Beam design and shot-peened to relieve stress. We then install silicon bronze bushings for increased wear resistance and precision ground alignment sleeves in the rod cap to prevent cap walk under high horsepower loads.

ALSO, we install ARP rod bolts to insure the highest quality available at the most critical point of the rod.

AND--each rod is multiple heat treated--each forging is quenched in a salt bath--each rod is x-rayed from four sides before and after machining--each rod is magnafluxed before, during, and after machining. A minimum of six separate times. Also we random test using the Rockwell hardness test and metallurgical analysis to insure the highest possible quality.

AND--all rods are weighed and packaged in balanced sets.
