Full Synthetic Heavy ShockProof Gear Oil (1 quart) has polyol ester base stocks, friction modifiers for clutch-type limited slip differentials, superior shear stability, reduced oxidation, & thicker oil between gear teeth.
Top Fuel Dragsters use it. You might be a candidate, too. This Heavy Shockproof Gear Oil contains the extreme pressure additives necessary for ultimate protection for road cars and racing vehicles, as well as friction modifiers for proper limited-slip operation. Heavy ShockProof Gear Oil has film thickness greater than an SAE 75W250, yet low fluid friction like 75W90. This product has many performance racing applications like Sprint/Midget/Dirt Late Model Differentials, Detroit Lockers and spools, NHRA Top Fuel, and Funny Car rear ends. It is not recommended for most synchro applications due to the product's extreme slipperiness.
