Detailed Description

PRT Performance Ride 990034 is an air suspension strut engineered for front suspension service on Mercedes-Benz GL-Class models equipped with AIRMATIC and without ADS. The assembly uses a twin-tube shock/strut design, an internal hydraulic damper, and an air bladder to support suspension height adjustment while maintaining controlled ride response. The progressive spring rate and shock spring-assisted construction help the unit respond smoothly across changing load conditions. The 990034 part number identifies this specific air strut configuration for fitment verification.

Brand Line: PRT Air Suspension Strut identifies the product family for air ride suspension service, with a focus on complete air strut assemblies rather than basic shock-only replacement parts. For Mercedes-Benz GL350, GL450, GL550, and GL320 owners, this line provides a direct-fit replacement path for the specified front suspension applications.

What It Helps Fix

• Loss of ride height control in air suspension systems
• Excessive bouncing or reduced damping performance
• Air spring leakage or weakened air bladder function
• Uneven front suspension response under load
• Noise or wear related to aging strut assemblies
