Product Description

Extreme Endurance for Drivetrain Performance. HIGHTEC RACING DIFFERENTIAL GEAR OIL SAE 75W-140 LS is a fully synthetic, high-performance gear oil engineered for the most rigorous racing conditions. Formulated with a blend of poly-alpha-olefins (PAO) and high-quality esters, this lubricant provides superior oxidation stability and a naturally high viscosity index. Developed and tested in the heat of competition including the Nürburgring 24h and VLN endurance series, it guarantees a stable, resilient lubricating film that ensures maximum reliability and protection for sequential manual gearboxes and axle gears equipped with multi-disc limited-slip differentials (LSD).

Important Usage Notes

• Performance Focus: This oil is developed specifically for extreme racing conditions where wear protection and reliability are the priority. It is recommended for competitive environments only and is not intended for day-to-day road use.
• Incompatibility: Not suitable for stepped automatic transmissions, DCT/DSG transmissions (oil-bath dual-clutch), or CVT transmissions.

Key Selling Points

• Proven in Endurance Racing: Validated on legendary circuits like the Nürburgring for unmatched durability.
• Limited Slip (LS) Performance: Specially optimized for axle gears with multi-disc locking differentials.
• Superior Shear Stability: "Stay-in-grade" formulation ensures consistent viscosity under extreme mechanical and thermal stress.
• Maximum Wear Protection: Outperforms API GL-5 requirements, providing a stable lubricating film even under peak heat and high loads.
• Advanced Synthetic Base: A sophisticated blend of PAO and ester oils for elite thermal and oxidation stability.
