Proper pushrod length is essential for achieving optimum valvetrain geometry. In fact, with today’s more-aggressive camshafts and higher valve-spring pressures, determining the right pushrod length has never been more critical to the performance and wellbeing of an engine.

Several factors work together to determine the required pushrod length—rocker arm brand, valve stem length, camshaft design, lifter style, engine deck height, and more—but figuring out the right pushrod length for your application is easy with the right tools.

This video shows you how to determine pushrod length using a few common mechanic’s wrenches, a crankshaft socket, and a Trick Flow pushrod length checker. Give it watch!
