For when a steel rod just won't get the job done, these are the go-to aluminum rods for those looking to maintain stock displacement on their built 2JZ-GTE or 2JZ-GE. These I-Beam connecting rods come standard with 3/8" ARP 2000 bolts with 3/8" ARP L19 bolts available as an upgrade. They use standard OEM size journals. We can also do these rods in the Honda journal . We recommend these rods to anyone looking to push the envelope and especially those who will be utilizing nitrous in large quantities.
R&R Aluminum Connecting Rods are CNC machined out of their proprietary aluminum alloys developed exclusively for R&R. The Pro-series alloy has up to 24% increased tensile and yield strength over competitors’ rod alloys. All alloys are cold extruded under 2,000+ tons of pressure to ensure consistent grain flow and density. This yields the strongest and lightest rod possible with an exceptional fatigue life and reduced elongation. As with all our connecting rods, material has been ultrasonically tested, bores are precision honed to standards, mating surfaces are standard or circle-loc™ serrated for super-strength and perfect cap to rod alignment, and all corners are blended to eliminate stress risers. All connecting rods come standard with ARP rod bolts.
You may ask, why are R&R’s rods made out of billets and not forgings. It is often believed nothing is better than a forged connecting rod. Even though our rods are manufactured out of what looks like a square stock, it should not be confused for a casting or a plate.
Unlike a forging in which the aluminum is literally pounded into the shape of a rod, our material is is cold worked, forced through a die at extreme pressures, to form the billets from which the Aluminum Connecting Rods are CNC’ed from. This work hardening builds the strength, grain structure, elasticity, and general characteristics that make our Aluminum Connecting Rods superior to common forgings. Our alloy is then further artificially aged and heat treated, then stress relieved though additional manufacturing processes.
