10 Best High Temp Wheel Bearing Grease 2025 in the United States

The AtomLube Ultra Heavy Duty Red Grease is a versatile high-performance lubricant designed for heavy-duty applications, particularly suitable for semi truck wheel bearings. It boasts an NLGI Grade of #2, indicating a good consistency for general-purpose grease applications. The grease is engineered to handle extreme pressures and high temperatures, making it ideal for demanding environments.

Its strong adhesive properties ensure it stays in place even under severe conditions, reducing the need for frequent reapplication. Additionally, it is waterproof and offers robust protection against corrosion and oxidation, thereby prolonging the life of the equipment it is used on. The product meets the NLGI GC-LB performance classification, which is a trusted standard for automotive wheel bearing and chassis grease.

The 2-pack of 14 oz. tubes offers a convenient supply for regular maintenance needs. This product appears to be a solid choice for those needing a durable and reliable grease for high-temp and heavy-duty applications, especially in the automotive sector.

The Allstar ALL78242 Timken High-Temp Synthetic Racing Wheel Bearing Grease is designed for the tough demands of racing hubs. Its synthetic base and special additives help protect bearings against wear, rust, and corrosion, which is crucial when bearings face extreme heat and stress. This grease also helps reduce operating temperatures and prolongs the life of the bearings, making wheel movement smoother and more efficient during races. The 14-ounce cartridge size is convenient for application and fits well in typical grease guns.

It is water-resistant and compatible with typical wheel bearing materials, which adds to its reliability in wet or harsh environments. This grease is specifically formulated to handle the high temperatures often experienced in racing conditions. It may be more than necessary for everyday or casual driving, as its formulation targets high heat and racing use rather than general maintenance.

For those involved in racing or high-performance driving that pushes wheel bearings to their limits, this grease offers strong protection and durability. For regular driving needs, a more general-purpose wheel bearing grease could be a more cost-effective option.

The Republic Oil Red High Temp #2 Grease is a versatile multi-purpose lubricant designed for demanding applications such as wheel bearings, chassis service, 5th wheels, and various machinery in agriculture and construction. It is formulated with a red lithium complex and has a high dropping point of 500°F, making it suitable for high-temperature environments. This grease is rated as NLGI Grade 2, which is common for automotive and industrial lubricants, providing a good balance of thickness and flowability.

One of its standout features is its excellent adherence, which ensures it stays in place even under extreme conditions. Its high water washout resistance and rust and corrosion prevention properties further enhance its durability and reliability, even in wet or humid environments. Additionally, it offers exceptional anti-wear and antifriction control, protecting moving parts from damage and reducing maintenance needs.

Because it is a high-temp grease, it might be overkill for less demanding applications, potentially not offering a cost-effective solution for simpler tasks. The packaging in tubes makes it easy to apply, though some users might find the size (14oz) requires frequent replacements for larger projects. Weighing in at 11 pounds for 10 tubes, it is relatively heavy, suggesting robust and quality content. This product is best suited for those needing a heavy-duty, reliable grease for high-temperature and high-pressure environments.
