Product Overview

The rear left air suspension spring, OEM number 2113201525, is the air-filled rubber bellow that supports the rear-left corner of a vehicle with air suspension. It carries the vehicle's weight on a cushion of compressed air, keeping the ride smooth and the ride height level. It flexes with every bump, and its rubber and crimped joints age with heat, mileage, and moisture, so it is a common wear item in the air suspension category.

A cracked or leaking air spring causes a sagging corner, a rough ride, and constant compressor load, so a precisely built replacement matters. GSK Auto manufactures this air suspension spring to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm the OEM number match before shipping.

What Is an Air Suspension Spring?

Function: The air suspension spring replaces a conventional coil spring, supporting the vehicle body on a cushion of compressed air and absorbing road shock while keeping ride height consistent.

Working Principle: A flexible rubber bellow is filled with air from the vehicle's compressor and control system. Adding or releasing air raises or lowers the corner to keep the vehicle level under changing loads, while the bellow flexes to cushion bumps.

Importance: The air spring affects ride comfort, ride height, and handling. A leaking spring makes the compressor work harder and can damage other suspension components if it is not replaced.

Common Failures & Signs: Vehicle sagging or sitting low at the rear left corner, especially after parking overnight. Air leaks from cracked or worn rubber. Air compressor running often or constantly. Suspension warning light on the dashboard. Harsh, bouncy, or uneven ride. Visible cracks, bulges, or wear on the bellow.
