BoostLine connecting rods represent one of the most advanced and reliable performance engine components available for serious builds. Engineered from the ground up for high-boost, high-horsepower applications, BoostLine rods are purpose-built to handle the extreme demands of turbocharged, supercharged, and nitrous-assisted engines — outperforming traditional designs in both strength and durability.
At the heart of every BoostLine rod is its patented three-pocket design, a revolutionary improvement over conventional H-beam or I-beam rods. This unique geometry combines the best characteristics of both styles, delivering up to 60 % more bending strength compared to common H-beam rods — giving you confidence when pushing your engine to its limits.
Manufactured from premium 4340 forged steel, BoostLine connecting rods are exceptionally strong yet maintain optimized weight for high-RPM performance. 4340 steel is a trusted choice in motorsport applications due to its excellent fatigue resistance and high tensile strength, ensuring rods can withstand extreme combustion pressures and torque loads without failure.
Every rod is fully finish-machined and inspected in the USA using aerospace-grade coordinate measuring machine (CMM) equipment, guaranteeing precision down to increments of .0001 inch. Each set even includes individual inspection reports so builders know exactly what’s in their engine.
BoostLine rods come standard with high-quality ARP 2000 hardware, with optional upgraded ARP 625+ Custom Age bolts for applications demanding additional durability. These premium fasteners provide superior clamp strength and long-term reliability in high-stress engines.
Performance ratings make BoostLine a standout choice: they support up to 1,000 HP in 4-cylinder engines, 1,500 HP in 6-cylinders, and an astonishing 2,000 HP in V8 builds. Whether you’re building a street machine, drag car, or race engine, BoostLine rods give you the structural integrity to go faster and finish stronger.
In short, BoostLine connecting rods deliver industry-leading strength, precision engineering, superior materials, and proven performance — making them an ideal choice for builders who demand power, longevity, and confidence in every rpm.
