Until 1993, meaningful research into valve train testing was not possible. It was only when the first SpinTron emerged, a revolutionary new valve-train test machine, that profound inadequacies in push rod design were revealed. The amount of column deflection of the conventional thin-wall 5/16in diameter push rods, and the lofting of the flat tappets as they became airborne while traveling over the nose of the camshaft lobes, amazed SpinTron creator Bob Fox and his collaborator the late Randy Dorton, tuning wizard at Hendrick Motorsports. Push rod design was about to change irrevocably. Fox had established his push rod company, Trend Performance, in Warren, Michigan, in 1988, after having worked as a tech representative on the phones at nearby Diamond Racing. While at Diamond he became aware of troubling quality issues in push rod manufacturing: pushrod lengths varied and their ends failed both ends.
Manufacturers would reduce the material thickness of the cup ends in order to form them, and as a consequence they would crack. Further, their lengths were so inconsistent that each push rod had to be inspected and graded accordingly. It was this encounter that caused Fox to enter the pushrod business.
By the end of his first year in business he had developed two new products: a 5/16-in push rod for small-block Chevrolets and a 3/8in for big-block Chevrolets.
By 1993 and aided by extensive data gathered by the SpinTron, he had vastly improved his push rod product line. Today, almost two decades later, Trend's jewel in the crown is their one-piece 7/16in double taper creation. Available from 6.000- to 13.000-inches long, and in increments of 0.025-inch, these 4130 chrome molybdenum push rods are used extensively in drag and oval track racing at all levels. Moreover, they’re affordable to all pockets because they’re made in production quantities and available as shelf-stock items.
