Since BoostLine's introduction to the high-horsepower world, our patented, 3-pocket design connecting rods have powered many different engines across many different disciplines of racing, from drifting to drag racing. With success in testing and development for up to 2,000HP with our connecting rod line for various gas engines, we recognized the need for reliable performance in the performance diesel world.


After 18 months of research, engineering, dyno testing, and everything in between, we are proud to announce BoostLine connecting rods specially designed for diesel applications. Launching with GM Duramax 6.6L and Cummins 5.9L and 6.7L offerings, no stone was left unturned in perfecting these rods for use in everything from a stock rebuild to 2,000+ ft/torque wielding race trucks. Forged from 4340 chromoly steel, finish machined, and shot-peened to reduce stress risers, these rods feature BoostLines tried and true 3-pocket design adapted for each specific diesel engine.
