Horstman high performance rods are CNC machined from billet 7075-T6 alloy aluminum. They are vibrahoned and shot peened to eliminate unwanted stress inducing tool marks. H beam models are proven to be the most reliable rods available. Horstman I beam models feature a drilled center for weight saving without sacrificing strength.
