Introducing Wiseco's new BoostLine connecting rods for the RB26DETT powertrain! Wiseco's engineering team created this new, patented 3-pocket design specifically for demanding turbocharged, supercharged and big nitrous applications. These connecting rods are ideal for today’s high horsepower engines and provide 60% more bending strength compared to common H-beam rods! Each rod is designed, finished and inspected in the USA and includes an inspection report from our quality team.
Increased Strengh, Reduced Weight!
The BoostLine rod takes the best attributes of an H- and I-beam rods and merges them into one. Even though the BoostLine rod is designed for heavy-duty use, they were able to keep the rod relatively light without compromising strength.
The challenge was to increase strength while minimizing mass. Generally, H-beam rods tend to concentrate stress at the radius between the beam and the big-end of the rod. The BoostLine 3-pocket plan dramatically improves the rod’s big end stability under tensile loads. Triangles are inherently strong and you can see this influence in the pocket shapes. This strength is especially critical at high RPM, where loads increase across the entire big-end area of the rod.
It was the demands in this area just above the big end that resulted in the patent-pending 3-pocket design. This arrangement drastically increases the rod’s bending strength giving it a 60 percent improvement in bending stress than a similar H-beam design, making it ideal for forced induction and high cylinder pressure engine combination. Simultaneously a 20 percent stress reduction in tension was observed with the BoostLine design.
These improvements were then applied to a high-quality 4340 chrome moly steel forging that is heat treated, shot peened, and fitted with ARP2000 capscrews before final finish machining. The ARP fastener is a critical component in the design using ARP’s heavily alloyed tempered steel that produces a tensile strength of 220,000 psi. Brittleness is often an accomplice of high tensile strength, but the ARP alloy has the ability to accommodate the loads that attempt to pull it apart, giving it both strength and malleability.

Boostline 625+ Bolt Upgrade
The BoostLine connecting rods come standard with the ARP 2000 rod bolt that is already a strength improvement over ARP’s industry standard 8740 chrome moly fastener. Now for sport compact applications. They are now offering a 625 Plus upgrade. The benefits of the ARP 625 Plus bolts are the superior cycle life and the 280,000 psi tensile strength, which is 27% higher than the standard ARP2000.
