Red Line MTL 75W80 GL-4 Gear Oil - Gallon
SKU: R00B 50205
Description
This gear oil is safe for brass synchronizers, as it lacks the reactive sulfurs found in most GL-5 oils that can cause damage. It provides a perfect synchronizer coefficient of friction for quicker shifts and eliminates notchy shifting, even in cold temperatures, while extending synchro life.
