KEIYSHOLCK Rear Air Spring Suspension 2-Pack for Mercedes GL/GLS/GLE/ML — OE Fit, High-Density Rubber

If your Mercedes feels saggy at the rear, rides harsh over bumps, or triggers a suspension warning, worn air springs are often the cause. These KEIYSHOLCK rear air suspension springs are built from high-density imported rubber and designed to match OEM fitment and reference numbers so you can replace failed units with confidence.

How do these air springs improve ride comfort and safety?

Replacing failed air springs restores proper damping and suspension travel, reducing bottoming out and harsh impacts. The reinforced rubber construction helps absorb vibrations and distributes loads more evenly, improving passenger comfort and vehicle stability.

• Imported high-density rubber for improved durability and load performance
• Reduces impact shocks and vibration transmitted to the cabin
• Helps maintain correct rear ride height and suspension geometry
• Designed for rear left and right placement to balance the axle
