FTC5403 Diff Oil Level Plug Discovery 2

Maintain proper differential fluid levels with this front and rear axle oil level plug for Discovery 2. Designed to seal the axle housing and allow accurate fluid level checks, this plug is a critical component in preventing leaks and ensuring proper lubrication.

Over time, factory plugs can corrode, seize, or become damaged during removal, especially in harsh environments. Upgrading to brass offers improved corrosion resistance and easier servicing compared to standard steel plugs, making future maintenance much simpler.

These plugs install directly into the axle housing using the factory threads. Available in brass, standard replacement options, or Genuine Land Rover, and offered as singles or pairs to suit your service needs.
