Synthetic 75W-90 Limited Slip Gear Oil utilizes the same synthetic oil technology as Driven’s 75W-140 Limited Slip Gear Oil to provide consistent limited slip differential performance. Ideal for both clutch type and torsion type differentials, this competition proven formulation utilizes a proprietary additive package that reduces drag, resists foaming and maintains its viscosity under extreme heat and high loads. It delivers outstanding performance in extreme environments like autocross, off-road trucks, UTVs, track day cars and race vehicles. Exceeds the performance requirements of API GL-5. Recommended for limited slip differential applications. Viscosity typical of 75W-90.
