• Soaks Up Bumps & Reduces Shakes: EA21-66-CS0 compresses and expands with air pressure, which softens the impact from potholes, speed bumps, and bumpy roads. It keeps fewer vibrations from reaching the car’s body, so passengers stay more comfortable.

• Supports Weight Well: It gives steady upward force to hold up the car’s weight—especially when you’re carrying people or luggage. The air pressure inside the spring adjusts automatically to keep the Haima S7 at its normal height, so the car doesn’t sag when it’s loaded down.

• Helps Adjust Height: If the Haima S7 has an air suspension control system, EA21-66-CS0 helps tweak how high the car is off the ground. That’s handy for different roads—like lifting the car a little for rough terrain.

• Tough Rubber Bladder: The main part is made of strong synthetic rubber that resists oil and aging—it meets car-grade standards. It can handle long-term high pressure (up to 8-10 bar), extreme temps (-30°C to 80°C), and road dirt without cracking or leaking air.

• Strong Metal Brackets: The top and bottom mounting brackets are made of stamped steel with an anti-rust coating. They hold the air bag spring tightly to the suspension frame and axle, so they don’t bend under heavy loads—and the spring stays securely installed.

• Sealed Air Chamber: The bladder has a multi-layer seal (with good-quality O-rings and pressure-resistant valves) that stops air from leaking. Even after using it for a long time, the air pressure stays steady—so you don’t have to re-inflate it often.

• Steady Comfort: Compared to old coil springs, EA21-66-CS0 uses air to absorb shocks, which cuts down on sudden jolts. It keeps the car’s body level, making the ride smoother—great for daily drives or long trips.

• Handles Different Weights: It works well whether the car is empty or fully loaded. Even when the Haima S7 is carrying a lot, the spring keeps the car at the right height—so braking and steering still feel responsive.

• Long-Lasting: The wear-resistant rubber and anti-rust metal make EA21-66-CS0 last a long time. With normal use, it can go 80,000-120,000 kilometers—so you don’t have to replace suspension parts as often.

• Fits Like the Original: It matches the Haima S7’s original suspension mounting spots, air ports, and size perfectly—1:1. You don’t need to modify anything when replacing it: just take out the old spring and pop EA21-66-CS0 in. It works seamlessly with the car’s original air control system.

• Haima S7 Air Bag Spring (Part No.: EA21-66-CS0) – Key Features

• Haima S7-Exclusive Precise Fit

• EA21-66-CS0 is made only for Haima S7 models with air suspension (built between 2015-2020). It matches the original suspension’s mounting spots, air ports, and size perfectly—1:1. You don’t need to modify anything when replacing the old part, so EA21-66-CS0 works seamlessly with the car’s original air control system.

• Dual-Core Functional Advantages

• Superior Shock Absorption: EA21-66-CS0 uses compressed air to flexibly squish and expand, which softens the impact from potholes, speed bumps, and bumpy roads. It keeps fewer vibrations from reaching the car’s body, making rides way more comfortable for passengers.

• Adaptive Load Support: It automatically adjusts the air pressure inside based on how much the car’s carrying—whether it’s empty or fully loaded. This keeps the Haima S7 at its normal height, so it doesn’t sag when you’ve got heavy cargo or people. Plus, it makes sure braking and steering still feel responsive.

• Durable Material & Structural Design

• High-Performance Rubber Bladder: The main bag of EA21-66-CS0 is made of car-grade synthetic rubber—it resists oil, aging, and high pressure (can handle up to 8-10 bar). It also stands up to extreme temps (-30°C to 80°C) and road dirt, so it won’t crack or leak air even after long use.

• Reinforced Anti-Corrosion Brackets: The top and bottom mounting brackets are stamped steel with an anti-rust coat. They don’t bend under heavy loads, so EA21-66-CS0 stays firmly installed and connected to the suspension frame and axle.

• Multi-Layer Sealed Air Chamber: It has good-quality O-rings and pressure-resistant valves to keep air sealed in. No air leaks mean the pressure stays steady, so you don’t have to re-inflate it often.

• Reliable Long-Term Performance

• Smooth & Stable Ride: Compared to old-style coil springs, EA21-66-CS0 is better at reducing sudden jolts. It keeps the car’s body level when you drive—perfect for daily commutes or long trips.

• Extended Service Life: The wear-resistant rubber and anti-rust metals make EA21-66-CS0 last a long time. With normal use, it can go 80,000-120,000 kilometers, so you won’t have to replace suspension parts as often.

• Easy Installation & Maintenance

• EA21-66-CS0 lines up directly with the Haima S7’s original mounting positions—no special tools or tweaks needed. After installing it, you just need to inflate it to the standard pressure (5-6 bar, check the car’s maintenance manual) and it’s ready to use. Replacing the old spring is super simple with this part.
