DA3964 Hitachi Air Suspension Compressor Pipe Installation Kit

Fresh Lines. Perfect Fit. Ready to Restore Pressure.
Fits: LR3, LR4, Range Rover Sport (Hitachi-Based Systems)

Replacing or reinstalling your Hitachi air suspension compressor? Don’t reuse brittle or leaking air lines. The DA3964 Hitachi Pipe Installation Kit includes everything you need to ensure a clean, leak-free connection between your compressor and air tank — built to factory spec for trouble-free performance.

Ideal for Land Rover owners replacing an original Hitachi compressor or reinstalling after service, this kit ensures your system maintains proper pressure and response.

  • Correct-length Hitachi-spec air line

  • High-quality fittings and connectors

Frequently Asked Questions:

Q: Will this work with an AMK compressor?
A: No. This kit is specifically for Hitachi compressors. For AMK conversions, use kit DA1888.
