CONNECTING RODS
Not all Connecting Rods are created equal. Not even ours. Probe maintains, in stock, FOUR distinct types of connecting rods to cover any situation. No matter which connecting rod you choose, these components are designed and manufactured to provide you unequaled quality and value.
These connecting rods are the hi-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. Recommended for engines in bracket, oval track, and most street and strip applications.

Manufactured for high horsepower applications where strength is mandatory but a significant reduction in weight is desired. Probe Lightweight Steel Connecting Rods are manufactured of 4340 Steel which provides the 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 dowelled to eliminate cap walk.
Probe H-Beam Steel Rods are precision forged of select 4340 aircraft quality steel, vacuum degassed to remove impurities. Probe 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.
For use in very high rpm engines, two barrel oval track, and drag motors with no power adders. Designed to provide maximum performance with a minimum of rotating mass. Painstakingly manufactured from premium 2 piece 4340 steel forgings, which will insure proper grain flow for maximum strength. Then fully machined on the latest in CNC equipment to ensure dimensional accuracy. Lastly ARP 8740 rod bolts are installed through the dowelled rod caps.
