Firestone 6859 Universal Heavy-Duty Air Compressor | On-Board Air Spring Inflation

The Firestone 6859 is a heavy-duty, universal-fit air compressor built to service air spring suspension systems, letting you inflate onboard air springs for load leveling without hunting down an external air source. It's designed to handle regular duty-cycle use in tow vehicles and trailers running air-assist suspension.

As a universal performance part, it's built to work across a range of air suspension setups rather than a single make or model, giving installers flexibility when adding or replacing an onboard compressor.

• Heavy-duty compressor for air spring suspension systems
• Universal fit across multiple air-ride applications
• Enables on-demand inflation without an external air source
• Firestone-branded performance-grade part

A practical addition for anyone running air springs who wants the convenience of adjusting ride height and load leveling from the driver's seat.
