Care information

To ensure optimal performance and extend the service life of your new trailer components, please follow these care guidelines after purchase:

  • Before installation, check all parts for shipping damage or missing components. Do not install damaged parts.
  • Always use correct tools and torque settings. Improper installation can lead to premature wear or failure.
  • For bearings, suspensions, and brake components, apply high-quality trailer grease before first use if not pre-greased.
  • Some parts (like brake assemblies) require a short break-in period to achieve full performance. Follow manufacturer instructions for best results.
  • Recheck fasteners, grease levels, and moving components after 100 miles of towing, then at regular intervals.
  • After exposure to water, road salt, or mud, clean and dry parts thoroughly. Apply anti-rust treatment if needed.
  • If storing unused parts, keep them in a dry, sealed container away from moisture and direct sunlight.

Product Overview:

This heavy duty trailer brake drum is designed for 8,000 lb axle applications, delivering reliable braking performance and durability for demanding towing conditions. Featuring a standard 8 on 6-1/2" bolt pattern and 9/16" wheel studs, it provides a secure and stable fit for a wide range of heavy trailer wheels. Engineered to work with 12-1/4" x 3-3/8" brake assemblies, it ensures proper brake shoe contact and consistent stopping power for both electric and hydraulic braking systems. 

Constructed from high strength materials, this drum offers excellent resistance to heat and wear, making it suitable for continuous heavy load use. It comes with bearings and studs pre-installed, allowing for easier installation and reduced downtime during maintenance. 

Designed as an oil bath lubrication system, this product allows bearings to remain continuous lubricated without frequent disassembly, helping improve longevity and reduce maintenance compared to traditional grease setups. 

Ideal for equipment trailers, flatbeds, car haulers, and other heavy duty applications, this oil bath drum provides a dependable replacement solution for maintaining safe and efficient braking performance on 8K axle systems.
