They feature a shot-peened surface finish to reduce stress profiles and improve fatigue life, along with dual-ribbing on the caps for big end roundness.

Show original supplier description
The K1 Technologies H-beam connecting rod set is engineered for demanding, high-stress racing environments. Each rod is forged from 4340 steel, providing exceptional strength, toughness, and resistance to impact. The manufacturing process includes a shot-peened surface finish to smooth potential stress areas and enhance fatigue life, while dual-ribbing on the rod caps helps maintain big end roundness under high RPMs. These connecting rods meet strict quality standards, including magnetic particle testing to ensure material integrity and bore tolerance compliance to within +/- .0001 inches. They are also balanced to within +/- 1 gram per end, ensuring consistent performance. The small ends are fitted with full-floating, precision-honed bronze bushings for excellent low-friction operation and high wear resistance. Fitted with ARP 2000 rod bolts, rated at 200,000 psi tensile strength, this set delivers a superior combination of strength and value. K1 Technologies aims to provide "RACEREADY" components with tight tolerances and superior finish work, setting them apart from standard imported rods. This set is designed for the Honda J35 engine and includes a set of 6 rods.
