Red Line Heavy ShockProof gear oil is a high-film, low-friction lubricant formulated for heavily loaded racing differentials, quick-change units, Detroit Lockers and problem gearboxes. Popular in Sprint, Midget, Dirt Late Model and NHRA Top Fuel and Funny Car rear ends, it offers film thickness above SAE 75W250 while retaining fluid friction like 75W90. Not recommended for most synchronized transmissions because its slipperiness can affect synchros.
