If you're driving a motorhome built on the Chevrolet P30 or P32 chassis (1963–2005), chances are your suspension could use some help.
These rigs weren’t exactly built for modern road conditions—and after a couple decades of weight, weather, and wear, your ride comfort and control may have taken a hit. That’s where air spring upgrades come in.
What Do Air Springs Do?
Air springs—also called air bags or air helper springs—are designed to support your suspension by adding adjustable lift and load-leveling capability. Installed between the axle and frame, they take on part of the vehicle’s weight, helping to stabilize the chassis and reduce the strain on your factory leaf springs.
This added support improves ride quality, minimizes rear-end sag, and helps maintain a level stance when hauling gear, towing a trailer, or carrying full tanks. Whether you're driving cross-country or navigating backroads, air springs give you better control, reduced sway, and a more predictable ride under load.
Benefits of Air Springs for P30/P32 Chassis
Upgrading your P30 or P32 motorhome chassis with air springs offers a range of real-world benefits RVers can feel behind the wheel:
Improved Ride Quality
Say goodbye to the harsh jolts and excessive bounce that come with factory suspension. Air springs help absorb road shock, reduce sway, and prevent bottoming out over rough pavement, potholes, and uneven terrain.
Leveling Support
Whether you're dealing with a rear-heavy load, a full water tank, or uneven cargo, air springs help maintain a level ride front to back and side to side. That means more even tire wear, better alignment, and a safer, more comfortable drive.
Improved Control and Stability
Air springs reduce body roll in corners and help stabilize the chassis during high winds, sudden lane changes, or when big rigs blow past. It’s the kind of confidence you want when piloting a large coach.
Adjustable Load Support
Air pressure can be increased or decreased manually (or automatically with an onboard compressor) to match your load. Tow a trailer one day, drive light the next—your suspension adapts with you.
Front vs Rear Air Springs
Most P30 and P32 chassis setups can benefit from both front and rear air springs. Front air springs help with steering stability and absorb harsh jolts from the road. Rear air springs provide extra support when towing a toad or carrying gear in the back.
If your motorhome leans, sags, or bottoms out, chances are one or both ends could benefit from a proper air spring upgrade.
Easy to Install, Easier to Maintain
Most air spring kits for the P30 and P32 chassis are designed as true bolt-on upgrades—no welding, cutting, or major modifications required. They utilize existing factory mounting points for straightforward installation, whether you’re a DIY enthusiast or having them professionally installed.
Once in place, you can adjust the air pressure manually with a standard air compressor, or take it a step further by adding an onboard air management system. This allows you to fine-tune ride height and support from the driver's seat—perfect for changing loads, campgrounds with uneven terrain, or quick adjustments before hitting the road.
