Product Description

The Manley 14032-4 H-beam connecting rod set is a premium performance engine component designed for high-stress applications in turbocharged MZR 2.3 L DISI engines - such as those found in 2007-2013 Mazdaspeed 3, and compatible with other Mazda vehicles running the same turbo engine. Built from high-strength 4340 steel and precision machined, these rods are heat treated, stress relieved, shot peened, and magnaflux tested to ensure maximum durability and performance under high RPM and boost levels.

Each rod is weight matched within tight tolerances and equipped with stout ARP 2000 fasteners to provide exceptional clamping force and strength. The H-beam design offers increased rigidity and reduced flex during aggressive driving, making this set ideal for both performance street engines and track-oriented turbo builds where strength and reliability matter. Sold as a complete set of four rods with cap bolts included, the 14032-4 provides a solid foundation for your high-performance rebuild or engine upgrade.
