Godspeed Project Mono-AIR Strut Lowering Kit for Mercedes-Benz 300D / 300E / 400E Sedan RWD (W124) 1986–1993 – Adjustable Air Suspension

Transform the stance, ride quality, and handling of your Mercedes-Benz W124 Sedan (300D / 300E / 400E, 1986–1993) with the Godspeed Project Mono-AIR Strut Lowering Kit, a premium air suspension solution engineered for enthusiasts who demand both performance and adjustability.

Designed for RWD W124 sedans, this Mono-AIR system replaces traditional springs with high-strength rubber air bags, allowing instant ride-height adjustment while maintaining proper suspension geometry. Whether you’re cruising at factory height or airing out for a clean, aggressive stance, this system delivers smooth operation and consistent performance.

At the core of the kit are performance-tuned mono-tube shocks featuring 32 levels of rebound damping adjustment, giving you complete control over how your vehicle responds to road conditions. Soften the setup for comfortable daily driving or dial in a firmer feel for confident highway stability and improved cornering control.

Godspeed Project air struts are built with durability in mind, utilizing anodized shock bodies, corrosion-resistant hardware, and multi-layer rubber air bags engineered to resist cracking and premature wear. The result is a reliable air suspension setup designed to perform long-term without compromising ride quality.
