These Speedmsater I-beam connecting rods incorporate all of the best features possible for an I-beam rod, including some strength adders found in H-beam designs. Speedmaster I-beam connecting rods are profiled with clearance for long stroke applications. These connecting rods feature a one-rib cap design for added strength and bearing support, polished beams to eliminate stress risers.
Speedmaster I-beam Street connecting rods are manufactured from high quality Forged 5140 steel. The rods are x-rayed and ultrasonically tested with all surfaces shot peened and stress relieved.
ARP connecting rod bolts are precision CNC-machined to exacting specifications and designed for optimum reliability. They are heat-treated and threads are rolled to provide up to ten times more fatigue strength. This makes them far superior to standard OEM fasteners in terms of durability, and fully capable of handling the extra stress of high-combustion engines.
