Engines modified to produce increased power and torque can rupture the oil film, leading to accelerated wear, particularly on flat-tappet cams. Pius, long-term storage invites harmful corrosion that can negatively affect engine performance. AMSOIL Z-ROD Synthetic Motor Oil contains high levels of zinc and phosphorus (ZDDP) to protect cams, lifters, rockers and other criticalparts against wear. It's also formulated with a unique blend of corrosion inhibitors to ensure protection during storage.
The AMSOIL V-Twin Oil Change Kit (HDCK) combines everything needed to perform an AMSOIL oil change on most 1999-2016 Harley-Davidson* motorcycles in one convenient package.
