The pushrod on a 5.7 Hemi is 7.225 inches long from the center of the rocker arm to the center of the valve stem tip, which may vary slightly depending on specific engine configurations. This length is necessary for proper camshaft lobe geometry and valve timing, as well as maintaining adequate piston-to-valve clearance at all times during operation. The fact that this size pushrod has been used in millions upon millions of factory engines means it’s an excellent choice for most applications where moderate performance gains are desired without sacrificing reliability or durability. Additionally, given its design and construction quality, it offers superior strength compared to many aftermarket alternatives which can be beneficial in high performance applications or extreme conditions such as drag racing or off-road use.
