BMW M3 Differentials

National® has built a reputation as one of the most respected names in the industry. We have offered premium sealing solutions for more than 75 years. Our design team keeps pace with the industry and provides advanced solutions for today’s vehicles.

Product Features:

• Designed to repair damaged, grooved or worn shafts
• Durable stainless steel construction for corrosion-free sealing surface that surpasses most original shaft specifications
• Ideal for a shaft where indications of seal wear, such as tracks or grooves have developed
• Ultra-thin construction (0.01/0.25mm wall thickness) allows original seal size to be used with minimal additional lip loading
• Easy to install with removable flange and installation tool
• Installation tool reduces sleeve distortion and allows for installation without removal from the shaft

This direct replacement differential cover matches the fit and function of the original equipment diff cover for a reliable, leak-free repair. It features a durable design, made to strict specifications, to help ensure reliable service life.

Product Features:

• Upgraded replacement – this differential cover features additional bracing and thicker materials for a more reliable repair.
• Application specific – made to match the fit and function of the original cover on certain BMW 3 Series model years.
• Durable materials – made of die cast aluminum
• Quality engineering – designed in the United States and backed by decades of automotive aftermarket experience

Valvoline High Performance Synthetic Gear Oil is the thermally stabile extreme pressure lubricant that offers outstanding protection for gearboxes and differentials in passenger cars, light trucks, and sport utility vehicles. Combined with high quality synthetic base oils, our formula’s superior additives help reliably safeguard against severe temperatures, shock loads, foaming, scuffing, scouring, corrosion and pitting in high load, high torque and high horsepower conditions. Can be used in conventional and limited slip hypoid differentials where GL-5 is specified as well as non-synchronized manual transmissions that require GL-4. Protect your gears with Valvoline, the #1 gear oil brand.

Product Features:

• HIGH PERFORMANCE EXTREME-PRESSURE ADDITIVES HELP MINIMIZE WEAR in high pressure and high temperature conditions
• EXCEPTIONAL HIGH AND LOW TEMPERATURE PROTECTION can easily handle both winter and summer conditions for dependable coverage and protection year-round
• REDUCES CHATTERING AND PROTECTS GEAR TEETH from oxidation, rust, and wear
• FIGHTS CORROSION AND RUST with emulsifying agents and safeguards against impurities, oxidation and thermal breakdown
• SUPERIOR ADDITIVES help reliably safeguard against severe temperatures, shock loads, foaming, scuffing, scouring, corrosion and pitting in high load, high torque and high horsepower conditions

High Performance Motor Oil API LICENSED MOTOR OIL Royal Purple High Performance Motor Oil combines premium base oils with proprietary additive technologies to create a high performance synthetic engine oil that optimizes performance and protection. Royal Purple High Performance Motor Oils carry the current API and ILSAC engine oil licenses, as well as the GM dexos1 gasoline engine oil approval. ILSAC GF-6 AND GM DEXOS1 Modern gasoline direct injection (GDI) engines have achieved levels of power and fuel economy never before possible in passenger car engines. As a result, smaller engines operate at much higher loads across all engine speeds. This has caused increased wear in critical areas of the engine, and created a destructive phenomenon called low-speed pre-ignition (LSPI). The unique, state-of-the-art additive technology in Royal Purple High Performance engine oils is designed specifically to address these issues, and help engines maintain performance and reliability.

Product Features:

• Better Wear Protection
• Increased Protection against Low Speed Pre-Ignition
• Increased Fuel Efficiency
• Better Protection for Vehicle Exhaust Emissions Equipment
• Improved Compatibility with Fuels Containing Ethanol
• Superior Corrosion Protection
• Made in USA

Whiteline’s differential bushing solutions ensure pinion angles are maintained while delivering an improved gear shift resulting in reduced initial torque loss and greater power transfer to the wheels.

Product Features:

• Designed with the installer in mind by reducing the need of specialised skills, tools and equipment.
• Protective plating on all metal components acts as a hard skin that is much tougher than conventional paint allowing this product to withstand the toughest conditions and resist corrosion for years to come.
• Internal grease reservoirs provide continual self-lubrication for optimum friction management.
