Frequently Asked Questions

Does this air ride kit fit 4WD trucks?

No. This air suspension kit is designed for 2WD (two-wheel-drive) models only. It will not fit 4WD Silverado or Sierra trucks.

What is the difference between Air Lift 3P and 3H?

The Air Lift 3P system uses pressure-based control, meaning it manages ride height using air pressure presets. The 3H system uses height sensors for more precise height-based control. 3P is simpler to install and works great for most street and show trucks.

Can I control the system with my phone?

Yes. The Air Lift 3P management system includes Bluetooth connectivity, allowing you to control your air suspension using the Air Lift mobile app or the included handheld controller.

Does this kit include everything needed for installation?

Yes. This complete kit includes the Air Lift 3P controller, manifold, compressors, tank, airlines, fittings, wiring harnesses, air bags, and mounting brackets.

Will this kit lay my OBS truck on the ground?

Most 1988–1998 Silverado and Sierra trucks can achieve a very low stance with this kit. However, additional modifications such as notching the frame or adjusting suspension components may be required for full ground clearance.

Are the air bags covered by warranty?

Yes. The included airmaxxx air bags include a lifetime warranty against manufacturer defects (excluding punctures, abrasions, abuse, or improper installation).
