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. BoostLine connecting rods are the complete package for every performance build, from powerful projects to all-out race cars.
