Everything in your engine needs to be built to handle heat. Everything you do for more performance makes that engine a much hotter place, which can subject your internals to excessive damage.

Manley Performance Products have a long history of making connecting rods with unbelievable strength and durability. Made from aircraft-quality, 4340 vacuum degassed material, each rod is forged for the perfect weight. Each rod is shot peened after machining and magnafluxing. The bores are perfectly round without tapering, and the bend and twist is tightly controlled.

These rods are available with a variety of bolts for your application. At Modern Automotive Performance, our mechanics have plenty of experience working with Manley connecting rods and can tell you exactly how their Pro Series I-Beam rods can benefit your vehicle.
