Probe Industries Machined Beam Connecting Rods are the high tech answer to hand polished connecting rods. A fully machined periphery provides a consistency of finish not possible with a hand finished beam. Built to withstand the brutal environments associated with virtually all high performance engines, CNC Beam Forged Steel rods are recommended for engines in bracket, oval track, and almost all street and strip applications.
Manufactured for high horsepower applications where strength is mandatory but a significant reduction in weight is desired, Probe Induistries Lightweight Steel Connecting Rods are manufactured of 4340 Steel which provide excellent strength to weight ratio and are about 50 grams lighter than most H-beams. The Lightweight features 7/16 ARP cap screws and are doweled to eliminate cap walk.
Probe Industries H-Beam Steel Rods are precision forged of select 4340 aircraft quality steel, vacuum degassed to remove impurities. They are forged in two pieces to insure proper grain flow, then all surfaces are CNC machined into a track proven H-Beam design and shot-peened to relieve stress. Silicon Bronze bushings are then installed for increased wear resistance and precision ground alignment sleeves are added to the rod cap to prevent cap walk under high horsepower loads.They are Drilled to provide pin oiling.

Silicon Bronze bushings are then installed for increased wear resistance and precision ground alignment sleeves are added to the rod cap to prevent cap walk under high horsepower loads. They are center drilled to provide forced oiling to the wrist pin. H/D H-Beam rods feature ARP-2000 rod bolts.
Specifically designed for use in very high rpm engines, two barrel oval track, and drag motors with no power adders. They are designed to provide maximum performance with a minimum of rotating mass. Probe Industries Ultralight Rods are painstakingly manufactured from premium 2 piece 4340 steel forgings, which will insure proper grain flow for maximum strength. They are then fully machined on the latest in CNC equipment to ensure dimensional accuracy. Lastly ARP 8740 rod bolts are installed through the doweled rod caps.
Manufactured for high horsepower applications where strength is mandatory, Probe Industries I-Beam Pro Connecting Rods are manufactured of 4340 Steel which provides excellent strength to weight ratio and are beefed up at the parting line for superior strength. The Pro features 7/16 ARP cap screws and are doweled to eliminate cap walk.
