Synthetic 75W-90 Limited Slip Gear Oil utilises next generation synthetic oil technology to provide consistent limited slip differential performance. Ideal for both clutch type and torsion type differentials, this competition proven formulation utilises 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.
