Construction & Design

The AST 5200 Series Coilovers feature a robust construction that combines a high-strength steel body with a precision-machined aluminum top mount. The coilovers utilize a monotube damper design, which provides superior heat dissipation and consistent damping characteristics under demanding conditions. The remote reservoir is connected via high-pressure hoses, allowing for increased oil capacity and better temperature control.

The adjustable components are engineered for ease of use, with smooth-threaded collars for quick height adjustments and precise damping knobs for tuning. The entire assembly is TIG-welded and finished with corrosion-resistant coatings, ensuring durability and longevity. The design emphasizes a low center of gravity and optimized suspension geometry to enhance handling and driver feedback.
