BoostLine was born in the R&D labs of Race Winning Brands to tackle the weakest link in high-horsepower, forced-induction engines. Their 4340 forged-steel rods feature a patented three-pocket I‑beam design, delivering 60% more bending strength and 20% less tensile stress compared to traditional H‑beam rods—enabling applications up to 2,000 HP.

Manufactured and finish-machined in Mentor, Ohio, each rod undergoes 26-point CMM inspection and includes detailed individual dimension reports—so builders know exactly what they're installing. BoostLine rods come standard with ARP 2000 bolts (upgradable to ARP 625+), and are rated for extreme use in turbo, supercharged, and nitrous engines—trusted by racers pushing four-digit horsepower number.

With ongoing expansion into new engine platforms, meticulous engineering, and a commitment to strength and reliability, BoostLine is the go‑to rod for performance builds where failure isn’t an option.
