Manley Pro Series connecting rods are forged from aircraft quality 4340 vacuum degassed material. Each rod is fully machined in the Manley Lakewood, NJ factory to the highest standards. Our signature "Turbo Tuff" design combines the appropriate weight and rugged strength for ultimate horsepower applications. Each rod is shot peened after machining and magnafluxed. Bores are round and without taper. Bend and twist is tightly controlled. Cap fasteners are 3/8" APR 2000 cap screws.
Optionally we can apply an oil shedding thermal dispersant coating to your rods. This coating will speed up heat transfer from the rod to the oil then shed it quickly to allow fresh, cooler oil to come into contact with the rod. This will improve heat related stress issues associated with high performance, high revving, motors. A 'must have' for those wanting the highest confidence in their builds.
