Ignoring a loud ticking noise in your top end can lead to a destroyed camshaft, but this genuine Mack component is the fix that brings your engine back to its original performance. It provides a smooth, hardened contact surface that eliminates the internal "slop" that drains your horsepower and wastes fuel. Because it is precision-ground to Mack's exact factory specs, you won't have to worry about the premature wear or metal shavings that come with inferior aftermarket parts. Getting this Mack 25502568 tappet into your valvetrain is the smartest way to ensure a quiet, efficient, and long-lasting engine.
