Build your Chrysler Gen III 6.2L / 6.4L HEMI V8 rotating assembly around Manley 14089-8, a 8-piece connecting rod set in the H-Beam range. This version combines 6.200 in. center-to-center length, a 2.252 in. big-end housing bore and a 24 mm (0.945 in.) wrist-pin configuration with 7/16 in. ARP 8740 cap screws. The exact dimensions, material and supplied fasteners identify the rod combination you are buying.
Manley’s H-Beam construction brings forged 4340 steel and precision-finished rod geometry together in a practical performance-engine upgrade. The manufacturing process includes heat treatment, stress relief, shot peening and magnetic-particle inspection. Attention to the housing finish, threads, bend and twist gives this series the machining detail expected in a purpose-built rotating assembly.
The 6.200 in. center-to-center length identifies this 6.2L/6.4L Gen III HEMI rod family. Its 2.252 in. housing bore is paired with the small-end dimensions listed for the exact part number. That combination keeps the HEMI application, rod series and piston-pin configuration clear from the first glance.
The 0.9457 in. pin-end bore and 2.252 in. big-end housing bore describe the two rod ends, while the 6.200 in. center-to-center measurement defines rod length. The crankshaft journal configuration is 2.126 in., paired with the housing bore specified below. Average rod weight is approximately 670 g per rod, giving this exact MPN a useful weight reference alongside its dimensions. The pin end measures 1.000 in. wide.
The supplied 7/16 in. ARP 8740 cap screws are part of this rod’s specification. This ARP 8740 version brings the stated fastener grade together with the 4340 steel H-Beam profile, pairing the documented fastener package with the forged rod construction.
