Air suspension universal kit

Types of Air Suspension Universal Kit

An air suspension universal kit replaces a vehicle's steel spring suspension with a system of air-filled rubber bags (bladders) called ""bags"" instead of struts. The bags inflate and deflate using an onboard air compressor and air lines. This allows for a smoother ride and better handling. An air suspension kit can be fitted to the front, rear, or all four corners of a vehicle. There are two main types of air suspension kits available: aftermarket air suspension kits and factory air suspension kits. The former is further divided into several types as detailed below:

• Bagged Air Suspension: This is the most common type of air suspension system. In bagged air suspension, rubber bags take the place of traditional coil springs. The bags inflate with compressed air when a load is placed on the vehicle, raising it. When the vehicle is unloaded, the air suspension universal kit's bags deflate, lowering the vehicle. This system allows for load leveling and can accommodate varying loads without affecting ride height or quality.
• Bag and Beam Suspension: This type of air suspension kit combines the bagged suspension system with a beam axle suspension. In the bag and beam suspension, the vehicle uses rubber bags instead of springs. The front and rear axles are also integrated into a single beam. This system is mainly used in trucks and off-road vehicles.
• Four Corner Air Suspension: In this type of air suspension universal kit, air springs are placed at all four corners of the vehicle. The four-corner air suspension provides better control and stability, especially for larger vehicles like trucks and buses. It also improves ride height adjustment and load leveling capabilities.
• Front Air Suspension: In this type of air suspension system, air springs are fitted to the front axle of the vehicle. The front air suspension improves ride quality and handling, especially in high-performance and luxury vehicles.
• Rear Air Suspension: This is the least common type of air suspension system. Air springs are installed on the vehicle's rear axle. The rear air suspension is popular in sports cars and high-performance vehicles. It improves ride quality, load handling, and stability during acceleration.

Maintaining an air suspension system is essential to ensure its longevity and optimal performance. Here are some general maintenance tips for an air suspension system:

• Regular Inspection

  Inspect the air bags, hoses, and other components for any signs of wear, damage, or leaks. Check for cracks, punctures, or tears that could compromise the system's integrity. Look for any signs of moisture or oil contamination, which could weaken the materials. Inspect the shock absorbers for any signs of leakage or reduced performance. Uneven tire wear or handling issues may do this.

• Cleanliness

  Keep the air suspension components clean and free from dirt, debris, and contaminants. Use mild soap and water to clean the bags and other parts regularly. Avoid using high-pressure washers or abrasive cleaners that could damage the materials.

• Air Filter Maintenance

  If the air suspension system has an air filter, inspect and replace it as needed. A clean air filter helps prevent dirt and debris from entering the system, prolonging its life.

• Proper Inflation

  Check the air pressure in the bags regularly and ensure it meets the manufacturer's specifications. Under-inflation or over-inflation can affect ride quality, load capacity, and component wear. Use a reliable pressure gauge to measure the bag pressure, and adjust it as needed using the onboard compressor or external source.

• Regular System Check

  Periodically, perform a complete system check. Ensure that the compressor functions correctly and maintains the required pressure in the bags. Listen for any unusual noises or operation issues. Inspect the pressure switch, relay, and other electrical components for proper operation. Check the wiring harness for any signs of damage, corrosion, or loose connections.

• Load Management

  If the vehicle has a load-carrying capacity, avoid exceeding it. Carrying excessive loads can strain the air suspension components and lead to premature failure. Distribute the load evenly across the vehicle to ensure optimal performance and stability.

How to choose air suspension universal kit

Wholesale buyers must understand the factors to consider when purchasing air suspension kits. Here are the factors in detail.

• The Vehicle Make and Model

  When selecting an air suspension system, the vehicle's make and model are essential considerations. This is because different vehicles use different suspension systems. Find out the compatible air suspension universal kits with the specific vehicle make and model.

• The Load Capacity of the Suspension Kit

  Different air suspension kits have various load capacities. Business buyers should select kits that can handle the loads transported by the vehicles without compromising performance.

• The Adjustable Height Range

  Some air suspension kits have a higher adjustable height range than others. Business buyers should choose kits with a height adjustment range that suits their needs. For instance, if they have a sports car that needs more height, they should select an air suspension universal kit with a greater height adjustment.

• The Type of Air Suspension System

  There are different types of air suspension systems. For example, some kits use double wishbone systems, while others use a strut-based system. Buyers should select a system that suits their needs and preferences.

• The Quality and Durability of the Components

  Buyers should select air suspension kits with high-quality components. The quality of the components will ensure that the suspension system is durable and reliable.

• The Ease of Installation and Maintenance

  Business buyers should choose air suspension kits that are easy to install and maintain. Some kits require professional installation, while others can be installed DIY.

• The Price of the Air Suspension Kits

  There is a price difference between various air suspension kits. Buyers should set a budget and shop for a kit that offers value for money. They should also avoid super cheap kits because they may have inferior quality components.
