Red Line Synthetic Heavy ShockProof Gear Oil 1 Quart | 58204
Video description
Looking for maximum differential protection under extreme loads? Red Line Synthetic Heavy ShockProof Gear Oil (58204) is a high-performance gear lubricant engineered for demanding street and racing applications. Its specialized synthetic formulation provides exceptional film thickness, extreme-pressure protection, and reduced friction to help protect heavily loaded gears and improve differential efficiency.
Formulated with fully synthetic polyol ester base stocks, Heavy ShockProof delivers excellent lubrication under severe operating conditions. Its high viscosity index helps maintain relatively consistent viscosity and film thickness as temperatures change, while specialized friction modifiers help reduce sliding friction in hypoid gears.
Designed for demanding applications such as racing differentials, Detroit Lockers, and spools, this heavy-duty gear oil provides substantial protective film thickness while maintaining low fluid friction. Each bottle contains one quart.
