Here is an excerpt from his web page
Our patented rod-to-cap design makes our rods the strongest in the world. In fact, our rods are over 30 % stronger than any rod on the market! Composed of space age billet aluminum, our rods are road tested to stand up to tomorrow’s heat and pressure engine performance standards.
At Groden Racing Rods we have eliminated rod failure with space age strength aluminum that allows no temperature growth. Throughout our rigorous engineering, testing and re-testing phases, our rods have unsurpassed quality control and craftsmanship, and are guaranteed not to have any forging flaws or cause distortion to the bores.
