FORTRESS ALUMINUM THREADED CAP SERVICE KIT 9,000 - 10,000 GD LBS

Protect your heavy-duty trailer investment with the Fortress Aluminum Threaded Cap Service Kit, designed for compatible 9,000–10,000 lb GD trailer axles. This service kit includes the replacement components needed to refresh your Fortress aluminum threaded oil cap, helping maintain a tight seal and proper lubrication for your oil bath hub system.

As trailers rack up miles, O-rings and sealing components can wear from heat, vibration, and exposure to the elements. Replacing these service parts during routine maintenance helps prevent oil leaks, keeps contaminants out of your trailer hubs, and protects your wheel bearings from premature wear and expensive downtime.
