Buying Guide: Key Considerations For Air Bag Suspension Kits
- Truck and trailer compatibility: Confirm make, model, year, and whether the kit fits your specific Silverado, Sierra, Ram, or other truck/ trailer combination. Some kits are model-specific while others are universal.
- Load rating and leveling: Check the maximum load capacity per bag and per system. Choose a kit that allows level towing under your typical payload and tongue weight.
- Installation complexity: Some kits are bolt-on with pre-drilled holes, while others require drilling or professional mounting. Consider your DIY comfort level and tool access.
- Operating environment: Look for durable materials and robust seals to resist road shock, potholes, and weather exposure during long hauls.
- Replaceability and compatibility with OEM parts: If replacing existing Firestone or Hendrickson components, verify cross-compatibility and replacement part numbers to ensure a proper fit.
- Maintenance and serviceability: Consider ease of maintenance, availability of spare parts, and standard port sizes for fittings.
Frequently Asked Questions
- What is the primary purpose of air bag suspension on trailers? To level the load, reduce sway, and improve ride quality by adjusting air pressure to support varying payloads.
- Do these kits require professional installation? Some bolt-on kits are designed for DIY installation, while others may benefit from professional mounting, especially on complex frame configurations.
- Can I mix components from different brands? Mixing widely different brands is not recommended unless compatibility is explicitly stated by the manufacturer for your vehicle model.
- Will air bag suspensions affect braking performance? Properly installed air bags can improve stability during braking by maintaining tire contact and reducing sway, but improper setup may cause handling issues.
- How do I know which load rating I need? Determine your typical payload, hitch weight, and towing conditions. Choose a kit with a higher capacity than your maximum expected load.
- Are there height adjustments available with these kits? Some kits offer height variation (drop/rise) to maintain a level tow, which is especially useful for uneven terrain or varying trailer heights.
