Air Suspension Buying Guide: The Five Core Components

A complete system needs more than air struts. Check each of the five core categories and the exact contents of every selected variant.

Suspension

Confirm the vehicle-specific application. ONAIR PAS offers 36-point manual damping, with camber plates and braided stainless front lines where applicable. Preparation is approximately 2 weeks after fitment confirmation.

Management

2V offers front/rear control, three presets and a key fob. 4V offers independent corners, five presets and Bluetooth. AirBoy provides another four-corner option with a retro-inspired digital controller.

Compressor and tank

The compressor replenishes the tank; the tank stores reserve. Compare current dimensions, ratings and duty limits, and plan mounting and electrical protection.

Water management

Manual and automatic heated traps have different operation and installation needs. Both should be accessible for inspection; tank drainage remains part of maintenance.

Finishing hardware and budget

Confirm airline, fitting thread types, mounting hardware, relays and fuses. Step 6 in the builder is optional. Shipping is paid, and discounts depend on eligible items and non-combination rules at checkout.
