Red Line SAE 75W-140 GL-5 Fully Synthetic Gear Oil Ester-Based LSD (Limited-Slip) Differential & Axle Fluid with Friction Modifier, High-Performance Hypoid Protection

Premium 75W140 Synthetic Final Drive Lubricant for Limited Slip and Axle Units

Looking for rear differential oil that stays strong under punishment and keeps your ring and pinion quiet and protected? This Red Line 75W140 performance final drive lubricant is built on high-end polyol ester chemistry for exceptional film strength, heat stability and long service life. It is a favourite for powerful road cars, track toys, 4x4s, tow vehicles and drift or drag builds.

We run this fluid in-house at MJ Modifications and it is consistently outstanding. Customers report smoother limited-slip operation, reduced whine, lower running temperatures and confidence under heavy loads.

What makes it a stand-out choice

• Ester-rich synthetic base stocks provide superb high-temperature resilience and extreme pressure protection for hypoid gearsets
• LSD ready formulation with friction modifier blended in, so most clutch-type limited-slip differentials do not need extra additive
• High viscosity index for consistent protection from cold starts through sustained high-load use
• Excellent shear stability and oxidation resistance to help maintain viscosity and extend service intervals
• Low sliding friction in the final drive can help reduce noise and heat while improving efficiency
• Suitable where API GL-5 is specified and recommended in applications calling for GL-6, MT-1, MIL-L-2105E and SAE J2360

Where it excels

Ideal as rear diff oil, axle lube and final drive fluid for high-torque street builds, track day cars, drifting, drag racing, towing and off-road use. A great match for powerful saloons, hot hatches, pickups and SUVs.
