When do I set the Air Lift PSI when connecting to my fifth wheel hitch?

If you have questions, we have answers! Join us LIVE every Wednesday at 4 p.m. PST for Talkin’ RV Tech.

Here is a clip from one of our recent shows where one of our viewers asked when they set the Air Lift PSI (pounds per square inch) when connecting to their fifth wheel hitch.

What is the Air Lift LoadLifter 5000?

The Air Lift LoadLifter 5000 is a type of air suspension kit designed for use on pickup trucks and other vehicles that tow heavy loads. The kit includes airbags that are installed between the vehicle’s frame and suspension, allowing the user to adjust the air pressure in the bags to level the vehicle and improve weight distribution when towing. This can help to improve the vehicle’s stability and handling, as well as reduce wear on the tires and suspension components.

The LoadLifter 5000 is designed for use with loads of up to 5,000 lbs. It comes with a wireless remote control that allows the user to easily adjust the air pressure while towing. The kit includes airbags, air lines, fittings, and a wireless control unit. For more information on this product, visit the Air Lift website.

Using the Air Lift LoadLifter 5000

The Air Lift PSI should be set based on the weight of the load on the hitch. The manufacturer’s instructions should provide guidance on the appropriate PSI range for different load weights. It is important to note that the PSI should be set when the vehicle and trailer are loaded and ready to tow, as the weight distribution can change during the towing process. Additionally, the PSI should be checked and adjusted as needed while towing to ensure optimal weight distribution and stability. It is also important to follow the manufacturer’s recommended guidelines for inflation, as over-inflation can damage the system and under-inflation can lead to unsafe towing conditions.

Some people think these systems add to GVWR or carrying capacity, which is completely false. While they help level the vehicle and distribute some of the weight, the vehicle’s GVWR, axle ratings, and total carrying capacity are unchanged.

I have one of these systems on my Silverado HD 2500. I like it for having the ability to level the ride, but I also realize I can’t put more load on the vehicle in total than I could without the system.

I’d like an explanation of how these are going to prevent excessive tire wear as the same weight I’d going to be on the tire whether you have standard suspension or the airlift. I can see the added help on the suspension as the air will be carrying some of the weight, but the tires are carrying all the weight all the time.
