Red Line® Heavy ShockProof® Gear Oil

Be the first to review this product



Red Line® Heavy ShockProof® Gear Oil is recommended for heavily-loaded racing differentials, transmissions, and problem gearboxes. Excellent for many performance racing applications like Sprint/Midget/Dirt Late Model Differentials, Detroit Lockers and spools, NHRA Top Fuel and Funny Car rear ends. Heavy ShockProof has a film thickness greater than an SAE 75W250, and yet low fluid friction like 75W90. Not recommended for most synchro applications due to the product's extreme slipperiness. Sold in quarts.
