Engineered for race cars and high performance street cars and trucks. Extreme pressure additive package protects rear end ring gears, pinions and bearings.
Used by top NASCAR gear builders and other leading mechanics, this petroleum-based, non-synthetic gear break-in 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 oil is designed for initial break-in to establish a protective extreme pressure film on the critical wear surfaces, and to smooth those surfaces during the process. Driven Break-In Gear Oil is meant for non-polished gear sets in order to provide the same surface-smooth effects of polishing without the added procedure. The oil can be run for the normal break-in cycle, and then a synthetic racing gear oil may be installed to get the most protection and efficiency from the rear gear and transmission.
