This is Manley's new H-Tuff H-Beam rod. This is a stronger beam construction, allowing you to make more power safely on an H-Beam than before. This H-Beam's construction can handle more power without adding considerable weight to the design. This rod bridges the gap between the previous h-beam design and the turbo-tuff I-Beam design which is considerably more expensive.
This is a great option for someone who is worried about maxing out the hp rating of the h-beam but not looking to step all the way up to an I-Beam.
