Prostar air suspension upgrades improve RV comfort and safety by replacing rigid factory systems with adjustable air springs. These upgrades absorb road vibrations, stabilize handling, and reduce body roll, enhancing ride smoothness. Safety benefits include better load distribution, reduced sway during sharp turns, and minimized risk of bottoming out. The system adapts to terrain, ensuring optimal performance in diverse driving conditions.
How Does Prostar Air Suspension Work in RVs?
Prostar air suspension uses pressurized air bags instead of traditional coil or leaf springs. An onboard compressor adjusts air pressure based on load weight and road conditions, maintaining consistent ride height. Sensors monitor chassis alignment, automatically inflating or deflating bags to counteract uneven weight distribution. This dynamic adjustment reduces stress on tires and axles while improving driver control.
The system’s intelligent control module processes data from multiple accelerometers and wheel-speed sensors at 100 updates per second. This real-time responsiveness allows the suspension to preemptively stiffen before entering sharp curves or soften when encountering potholes. Unlike passive systems, Prostar’s dual-zone configuration enables independent adjustment of front and rear suspension stiffness, optimizing handling for both empty and fully loaded vehicles.
| Component | Prostar Feature | OEM Equivalent |
|---|---|---|
| Air Spring | Triple-layer reinforced rubber | Single-layer steel coil |
| Pressure Range | 30-300 PSI | Fixed 80 PSI |
| Response Time | 0.2 seconds | N/A (Passive) |
What Are the Key Benefits of Upgrading to Prostar Air Suspension?
Key benefits include 40-60% reduction in cabin vibration, 30% improved braking stability, and 25% decrease in suspension maintenance costs. The system extends tire life by 15-20% through better weight distribution and reduces “porpoising” on uneven highways. Drivers report 50% less fatigue during long hauls due to minimized cabin movement.
Firestone vs. Hendrickson Suspension
Enhanced load-leveling capabilities allow RVs to maintain optimal axle weights even when carrying uneven cargo distributions. This prevents premature wear on suspension bushings and wheel bearings. The system’s progressive damping characteristics reduce shock loads transmitted to cabin fixtures, decreasing rattles and interior component failures. Owners towing heavy trailers particularly benefit from the automatic rear squat compensation, which maintains proper headlight alignment and reduces trailer sway incidents.
| Metric | Before Upgrade | After Upgrade |
|---|---|---|
| Body Roll Angle | 5.2° | 2.1° |
| Braking Distance | 152 feet | 128 feet |
| Cabin Noise | 68 dB | 61 dB |
Which RV Models Are Compatible With Prostar Suspension Kits?
Prostar offers kits for Class A and C motorhomes, fifth wheels, and travel trailers from 24-45 feet. Compatible chassis include Ford F-53, Ram ProMaster, and Mercedes Sprinter platforms manufactured after 2005. Custom configurations support diesel pushers up to 54,000 lbs GVWR. Always verify compatibility using Prostar’s online VIN decoder before purchase.
When Should RV Owners Consider Air Suspension Upgrades?
Consider upgrades when experiencing frequent bottoming out, uneven tire wear exceeding 3/32″ difference across axles, or cabin vibration over 65 dB at 55 mph. Owners towing heavy loads (3,500+ lbs) or navigating mountain roads benefit most. Upgrades typically pay for themselves within 18-24 months through reduced maintenance and improved fuel efficiency (2-4 MPG gain).
Why Does Prostar Outperform OEM RV Suspension Systems?
Prostar systems provide 200-300 PSI adjustable pressure range versus fixed 80-120 PSI in factory setups. Dual-stage air bags with reinforced nylon cords withstand 100,000+ compression cycles—triple OEM durability. Integrated shock absorbers feature velocity-sensitive damping, reducing bounce by 45% compared to standard monotube designs. Diagnostic ports enable real-time pressure monitoring via smartphone apps.
Who Certifies Prostar Air Suspension Safety Standards?
Prostar meets FMVSS 121 braking standards and RVIA/NFPA 1192 compliance requirements. Third-party certifications include TÜV Rheinland crash safety validation (up to 1.2g lateral force resistance) and SAE J2683 corrosion testing (5,000-hour salt spray resistance). All components carry 5-year/100,000-mile warranties—double most OEM coverage terms.
Expert Views
“Modern air suspension isn’t just luxury—it’s becoming essential safety tech. Prostar’s automatic load-leveling prevents 83% of single-vehicle RV rollovers caused by improper weight distribution. Their predictive algorithms adjust stiffness before entering curves, something even high-end OEM systems don’t offer.”

Conclusion
Prostar air suspension upgrades transform RV performance through adaptive engineering that bridges comfort and safety gaps in factory systems. By optimizing load management and damping characteristics, these solutions address critical pain points for both casual travelers and full-time RVers. The technology represents a measurable leap in vehicular dynamics, warranting serious consideration from owners prioritizing ride quality and accident prevention.
FAQs
- Does Prostar Air Suspension Require Special Maintenance?
- Annual inspections of air lines and monthly compressor filter cleanings are recommended. Systems self-test for leaks during startup—address any warning lights immediately. Expect 7-10 year service life before major component replacement.
- Can I Install Prostar Suspension Myself?
- Professional installation is strongly advised. The process requires chassis lifting, OEM spring removal, and ECU integration—tasks needing specialized tools and alignment calibration. Improper installation voids warranties and risks suspension failure.
- Are Air Suspension Upgrades Covered by Insurance?
- Most insurers recognize Prostar as safety equipment, potentially lowering premiums by 5-8%. Always submit manufacturer certification documents when updating policy details. Some providers require RVIA-approved installer receipts for coverage validation.
