FAQ
Will an air ride suspension kit fix a permanently sagging rear end on my truck?
No. Air ride suspension kits are designed to level your vehicle when carrying a load, not to correct a permanent sag caused by worn-out leaf springs or coils. If your truck sits low when empty, you likely need to replace your rear springs first. An air kit will only be effective once the vehicle’s base ride height is correct.
Can I install an air ride suspension kit on a truck that already has a factory air suspension?
It depends. Factory air suspensions, like the Magnetic Ride Control on the Cadillac Escalade or GMC Denali, are integrated with the vehicle’s electronic stability control and ride height sensors. Adding an aftermarket kit can interfere with these systems. If you need to replace a failed factory compressor or bag, look for a direct-replacement kit like the TRQ system. For vehicles with standard coil or leaf springs, an aftermarket air kit is a straightforward upgrade.
What’s the difference between air springs and air bags in these kits?
In the context of aftermarket truck suspension, the terms are used interchangeably. Both refer to a reinforced rubber and fabric container that inflates inside a metal sleeve or bellow. The Air Lift LoadLifter 5000 series uses a 2-ply fabric air spring, while the Firestone Red Label uses a similar double-convoluted bellow design. The key difference is the internal construction and shape, which affects the spring rate and ride quality, but both serve the same purpose of load leveling.
Do I need a separate air tank with an on-board compressor system?
Most on-board compressor systems for suspension are designed as “direct-inflate” systems where the compressor fills the air springs directly without a storage tank. The Vixen Air kit is an exception, as it includes a 5-gallon tank. A tank provides a reserve of pressurized air, allowing you to make multiple pressure adjustments without waiting for the compressor to cycle. For typical towing applications where you change pressure once per trip, a tank is not strictly necessary but can be a convenience.
Final Thoughts: The Verdict
For most full-size truck owners who tow frequently, the best air ride suspension kit winner is the Air Lift LoadLifter 5000 (57289) because it offers a proven, vehicle-specific fit with a 5,000 lb load leveling capacity, a limited lifetime warranty, and a price point that makes it a solid mid-range investment. If you want wireless, on-the-go pressure control and programmable presets, grab the maXpeedingrods Wireless On Board Air Compressor System. And for the absolute strongest, most durable build for heavy commercial use or extreme loads, nothing beats the Firestone Airide Red Label Kit with its 7,500 lb capacity and no-drill installation.
