Description
Big Twin transmissions demand lubricant engineered for extreme heat and stress—stock oils fall short under aggressive riding or extended operation. KLOTZ KH-GL140 is formulated specifically for Harley-Davidson Big Twin gearboxes, delivering the thermal stability and wear protection needed to keep your transmission running cool and reliable. A single quart of 100% synthetic fluid replaces your factory lube and transforms shift quality while reducing operating temperatures.
