Description

GL-4 Synthetic 80w-90 Gear Oil (1 qt. bottle) has high-shear race protection, protects internal synchronizers, extends oil change intervals, & is safe to be used on all yellow metals.

Petroleum-based Break-In Gear Oil allows gear teeth to break-in quickly while improving their surface finish. By polishing the gear teeth, micro-pitting is eliminated to improve gear durability. A smooth gear surface can carry more load and last longer. The Break-In Gear Oil can be run for the normal break-in cycle, and then install a synthetic racing gear oil to get the most protection and efficiency from the rear gear and transmission.
