Superior H-Beam Rod Strength!

Manley developed H-Tuff connecting rods to fill the void between standard H-beam and Pro Series I-beam connecting rods. Unique features to the H-Tuff series include double-ribbed pin surround and increased cross-sectional thickness in critical areas; for a connecting rod that will handle higher boost and horsepower levels than a standard H-beam. H-Tuff rods are built to the same quality-control standards and tolerances as all Manley connecting rods.
