Red Line Heavy ShockProof Gear Oil is a gallon intended for heavily loaded racing differentials and transmissions, including Sprint, Midget, Dirt Late Model, quick change differentials, Detroit Lockers and NHRA Top Fuel/Funny Car rear ends. It provides film thickness greater than SAE 75W250 while maintaining relatively low fluid friction, but is not recommended for most synchro applications due to extreme slipperiness.
