BoostLine connecting rods are designed and built for the stressful demands of high-powered, forced induction and nitrous engines. Proven in the lab and on the track in 1,500HP+ five and six-cylinder engines from the iconic 2JZ to EcoBoost 3.5Ls to Audi RS2s, BoostLine rods are forged from premium 4340 steel and utilize a patented, three-pocket design, maximizing strength while minimizing rotating weight. This revolutionary design dramatically improves each rods’ big-end stability under tensile loads and provides a 60% improvement in bending strength and 20% stress reduction in tension compared to H-beam designs, benefits crucial to durability in four-digit-horsepower engines. Each rod is equipped standard with industry leading ARP hardware and is subject to a 26-point, CMM inspection with all critical dimensions provided via an inspection card included with every set of rods.
