RETRUE Onboard Air Compressor System
The RETRUE kit is designed for universal air bag suspension systems across many pickup models including Ford, Chevrolet, GMC, and Dodge. It inflates quickly, reaching up to 100 PSI with measured time-to-pressures such as 50 PSI in about 80 seconds and full inflation in under four minutes. The in-cab control keeps air adjustments within the driver’s reach, reducing over-inflation risk by requiring continued pressure on the button to inflate. Real-time pressure readouts enhance accuracy and safety for smoother rides and better load handling.
VIAIR 444C Dual Air Compressor (2 Pack)
The VIAIR 444C system provides high-performance dual compression for continuous air suspension adjustments. Each compressor supports high output with a combined flow suitable for large tanks, suspensions, air horns, and related components. With a 100% duty cycle at 100 PSI and 50% at 200 PSI, it’s well-suited for frequent adjustments. The package includes 18-inch stainless steel braided leaders, a thermal overload protector, and an 8-foot power cord, making it a robust choice for heavy-duty setups and demanding road conditions.
maXpeedingrods On Board Air System
The maXpeedingrods system provides a single-path air delivery with an onboard compressor that can reach up to 100 PSI. It’s designed for easy inflation of air springs, accommodating up to two bags simultaneously from the comfort of the cab. The kit emphasizes user-friendly operation and quick upgrades for smooth rides under heavy loads or trailer towing. A compact, adaptable design helps installation in various vehicle layouts, reducing downtime and complexity.
Air Lift Air Shock Controller with Gauge
This Air Lift controller provides driver-friendly control of air shock pressure directly from the cab. It features a universal connector compatible with most shocks, including factory-installed units, and includes a rugged onboard compressor. The combination enables quick ride height adjustments and pressure tuning to maintain level stance and stability across varying loads and road conditions. It’s a practical upgrade for those seeking straightforward operation and reliable performance.
CNRAQR 3 Gallon Tank With Onboard Compressor
The CNRAQR kit combines a 3-gallon air tank with an onboard 150 PSI compressor, suitable for suspension systems that demand steady air supply and reliable inflation. With a maximum working pressure of 150 PSI and peak intermittent pressure up to 250 PSI, it handles heavy-duty tasks quickly. The kit emphasizes durable construction, weather resistance, and a 2.03 CFM flow rate for faster inflation, helping reduce waiting times during critical adjustments on the road.
Buying Guide: Key Purchase Considerations
When selecting an air compressor system for air suspension, consider these factors to ensure the best fit for your vehicle and driving needs.
- Pressure Range and Duty Cycle: Look for units that reach at least 100 PSI with a high-duty cycle for continuous adjustments during long trips or frequent height changes. Dual compressors can offer redundancy and faster inflation for larger systems.
- Installation and Compatibility: Check whether the kit is designed for universal use or requires specific vehicle models. Consider whether you will install a tank, a single-path system, or a dual-path setup to fill two bags at once.
- In-Cab Control and Monitoring: A driver-friendly interface with real-time pressure readouts improves safety and accuracy. Paddle valves, gauges, and programmable presets add convenience for on-the-fly adjustments.
- Durability and Weather Resistance: For trucks and off-road use, components should resist dust, moisture, and vibration. Look for IP-rated components and weatherproof housings.
- Tank Size and Air Flow: Larger tanks store more compressed air for sustained adjustments, while higher CFM ratings shorten inflation times. Balance tank size with vehicle space and weight considerations.
- Ease of Installation: Some kits require drilling and substantial fabrication, while others are more plug-and-play. Consider your DIY skill level and available workshop resources.
- Maintenance and Replacement Parts: Availability of replacement parts, hoses, and seals affects long-term reliability and downtime.
- Price of Ownership: While not listing prices here, compare total system cost, including hoses, fittings, and mounting hardware, to ensure value over the system’s life.
In selecting among these options, consider your vehicle type, typical loads, desired ride comfort, and whether you prioritize in-cab operation, faster inflation, or higher PSI capacity for aggressive off-road use. For a balanced setup on a mid-range pickup, a dual-compressor arrangement with a reliable gauge and an adequate tank often delivers consistent performance, smoother adjustments, and flexibility for various bags and loads.
