Max Gear is recommended for truck and automotive differentials, outboard motor lower units or in rear axles or manual transmissions requiring an API fluid. Max Gear is a high performance automotive gear oil designed to provide maximum protection to heavily loaded gears while increasing power throughput through the drive train. Max Gear virtually eliminates both gear and bearing wear-even under severe squeeze film conditions caused by extremely high loads, sudden shock loads or low RPMs. Slippery, synthetic molecules not only reduce wear and friction but significantly increase Max Gear’s cold weather fluidity and lubricity, making it the ideal choice for vehicles operating in cold climates. Gears run smoother, quieter, cooler and longer without overhauls. It is noncorrosive to both ferrous and nonferrous metals.

We’ve squeezed innovation into every ounce of Valvoline FlexFill SAE 75W-140 Full Synthetic Gear Oil, the ultimate gear protection in hypoid rear differentials and non-synchronized manual transmissions. Our unique new flexible pouch makes getting into the tightest places to lubricate gears easier than ever and with less waste. The superior detergent package-based formulation contains fully synthetic basestocks and special additives that help protect parts from rust and corrosion while providing exceptional high and low temperature protection and excellent thermal stability, especially in demanding driving situations such as towing and off-roading. It contains an extreme pressure additive for better load carrying capacity, wear resistance additives that assist in protecting gear teeth, a limited slip additive for optimal clutch pack performance, and an anti-foaming agent for better lubrication and service life. Valvoline FlexFill SAE 75W-140 Full Synthetic Gear Oil is recommended for use in axle applications requiring factory-fill or drain-and-fill levels for limited slip performance. Volume: 1 quart.

Union 76 gear oil is a conventional non-synthetic 80W90 formulation designed for all types of differentials.

Redline Heavy Shockproof Gear Oil is formulated to provide lasting protection.

Choosing an automatic transmission fluid just got easier. Valvoline Full Synthetic MaxLife Multi-Vehicle ATF, the #1 ATF product, is suitable for use in 95% of ATF vehicles in operation with US registered light duty applications. And now, it€™s also recommended for most belt and chain-driven continuously variable transmissions (CVT). Featuring advanced additives to prevent the major causes of transmission breakdown, it€™s designed to help prevent leaks, reduce wear and tear, and maximize performance €“ all for much longer than conventional fluids. It has improved thermal stability for longer fluid life, better viscosity stability for consistent transmission operation, and frictional enhancements for smooth gear engagements. Whether your vehicle has a CVT or traditional automatic, Valvoline MaxLife Multi-Vehicle ATF is suitable for a broad range of transmissions including Ford, GM, Toyota, Honda, Nissan, Hyundai, Subaru, BMW, Mercedes, Volvo, VW and Audi vehicles. It€™s specifically recommended for use in the following applications: GM DEXRON-II, DEXRON-III, DEXRON-VI, and DEX-CVT; Ford MERCON LV; Toyota/Lexus Type T, T-II, T-IV, WS, CVTF FE, and CVTF TC. For the many miles ahead, trust your transmission with Valvoline, the #1 automatic transmission fluid brand.

Modern transmissions are better than ever, with more gears to help improve fuel efficiency and acceleration. Greater performance calls for greater protection. Valvoline Extended Protection Full Synthetic ATF features our exclusive Dual Defense Additive Technology for two layers of protection against metal-on-metal contact and thermal breakdown, all while minimizing wear on clutch components. In fact, Valvoline Extended Protection Full Synthetic ATF is 45% stronger against breakdown compared to major brand DEX/MERC oxidative PDSC performance. Proven to maximize transmission life, our patented formula keeps your modern vehicle shifting smoothly, mile after mile, with the ultimate protection you can only expect from Valvoline, the #1 ATF brand.

Value-priced seal meets all cataloged application requirements.

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.

Our wheel seals are engineered using only the highest-quality materials to meet vehicle manufacturer specificatons. We work with suppliers to design seals that meet FAG’s quality standards. Seals are designed to protect wheel end components from contamination – such as dirt, dust, and moisture – and prevent the loss of grease over the life of the bearing. The specifications for wheel seals are very demanding, and the type required depends on the specific application, position and vehicle class.

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.

These Yukon replacement diff covers take your rig a step beyond the boring factory look. They are the stock OE design finished in chrome.

If you venture off the beaten path, plow snow, or subject your truck or SUV to extreme conditions, this rugged rear differential cover will boost the protection and personality of your vehicle’s drivetrain. Instead of the vulnerable thin stamped steel original equipment cover, this diff cover is precision-engineered from thick ductile iron and boasts an attractive, corrosion-resistant wrinkle coating. Rocks, trail hazards and damaging debris can easily ding an ordinary differential cover, leading to oil leaks and cracks. Plow trucks undergo stress due to the weight of salters and plows, and the no-brakes impacts of hidden potholes, coupled with the corrosive nature of all the salt season after season. This cover also features two filler plugs, which can help ease the difficulties of filling through the factory plug located on the axle housing. The cover is also fitted with a drain plug to make fluid exchanges quick, easy, and remove the need for replacing the differential cover gasket. This extra-rigid replacement will help keep critical components safe while adding a serious cool factor, especially on lifted vehicles. Want to customize your diff even more? We’ve made the stainless steel Dorman logo plate removable so you can replace it with the plate and logo of your choice. The cover comes complete with all necessary bolts and plugs for a complete upgrade.

These Yukon replacement diff covers are a direct bolt-on.
