The Multi-Stage Buffer Suspension Control Arm Bushing for Mercedes-Benz is a composite outer diameter bushing designed for Mercedes-Benz suspension systems. Its core feature is a stepped structure with two outer diameter sizes: 40mm and 25mm. This allows for varying degrees of locking force at the mounting site and multi-stage buffering across different force amplitudes. The 38mm thickness combined with a 12mm precision inner diameter helps guide the swing arm's movement. This highly functional part aims to finely tune chassis response.

Stepped Outer Diameters: 40mm and 25mm specifications. 
Core Thickness: 38mm overall. 
Precision Connection: 12mm inner diameter ensures bolt stability. 
Geometry: Combined parameters of 40mm * 37.9mm * 12mm. 
Composite Design: Leverages diameter differences for segmented press-fitting, reducing single-point pressure on the mounting hole.

Multi-stage Damping Feedback: Provides different damping coefficients under small vibrations versus large impacts. 
Accurate Axial Positioning: Ensures the bushing does not shift axially under dynamic loads. 
Installation Stress Optimization: Segmented outer diameters make press-fitting more controllable, reducing scratches on aluminum seat holes. 
Lateral Stability Improvement: The 40mm large end provides necessary lateral rigidity for cornering. 
Clearance Reduction: Precision tolerance control eliminates minor joint looseness for more direct steering.
