Trend Performance Products Engine Valve Spring Shim - 03-1960

In 1993, a breakthrough in valvetrain testing technology was born inside the walls of what would become Trend Performance. SpinTron emerged, launching a tool to do meaningful research into valve train testing and technology. This testing exposed profound inadequacies in pushrod design which lead to the creation of Trend Performance, a leading manufacturer in high quality pushrods and valvetrain components for internal combustion engines. Headquartered in Warren, Michigan, Trend Performance continues to set the industry standard in high performance valve train technology.
