Air Lift Air Shock Controller Onboard Compressor and Dash Gauge - 25804, Compact 200 PSI Kit

The Air Lift 25804 Air Shock Controller Kit is a compact onboard compressor and dash-mounted pressure gauge that lets you inflate or deflate factory and aftermarket air shocks from the driver's seat without an external tank.

This complete kit combines a small but durable compressor, a single-needle dashboard gauge with on/off and one-touch deflate controls, and all necessary fittings and air line to connect to most air shock systems using an existing T-fitting. Designed for simple DIY installation and powered through a 15-amp fuse connection, the 25804 gives you direct control over ride height and shock firmness for improved comfort and clearance when you carry heavy loads or encounter rough roads.

How does the 25804 let me change my ride height and comfort?

The kit pressurizes or vents air shocks so you can quickly fine-tune chassis height and shock firmness. The dashboard gauge shows pressure up to 200 psi (with a practical upper recommendation), and the one-touch deflate makes lowering fast and easy.

• Onboard compressor fills shocks without a separate air tank
• Dashboard-mounted gauge with simple push-button operation
• One-touch deflate for rapid lowering
• Works through your vehicle's existing air shock T-fitting (T-fitting not included)

What components are included and how hard is installation?

The 25804 ships with the compressor, dash gauge panel, air line, mounting hardware, electrical connections, and an illustrated manual. Installation is aimed at DIYers familiar with basic vehicle wiring and under-dash fuse access; no permanent battery tap or tank mounting is required.

• Rugged compact compressor ready for under-dash mounting
• Generous length of air line and universal connector for most shocks
• Self-tapping screws for dash gauge mounting and full hardware kit
• Power via a 15-amp minimum fuse connection; instructions included

Will the controller work with my vehicle and air shocks?

The kit is built to be compatible with most factory and aftermarket air shocks using a standard T-fitting. It can pressurize two pairs of air springs from one compressor when plumbed accordingly, but it’s not intended for heavy commercial or racing applications.

• Universal connector suitable for many factory-installed air shocks
• Designed for cars, vans, light trucks and motor homes (catalog-listed applications)
• Not meant for commercial, racing, or extreme off-road duty
• Check vehicle-specific fitment and T-fitting availability before purchase

What should I know about durability, pressure limits, and warranty?

The compressor and gauge are built for regular passenger use, with a two-year limited warranty against defects for retail purchasers using listed applications. Note that running pressures above the recommended threshold can shorten compressor life and increase leak risk at fittings.

• Two-year limited warranty for original retail purchaser on catalog-listed vehicles
• Gauge registers pressures up to 200 psi; avoid sustained use above 160 psi
• Includes corrosion-resistant fittings and mounting hardware
• Routine inspection and proper installation improve longevity

Who is this for: Drivers who want an easy, in-cab way to adjust air shocks — commuters towing trailers, weekend adventurers carrying heavier loads, or anyone seeking flexible ride height and comfort control without installing a separate air tank. Avoid if you need high-duty commercial performance or race-spec systems.
