Construction & Design

The AST 5100 Street Series Coilovers feature a robust construction designed for reliability and performance. The shock bodies are made from high-strength steel with a corrosion-resistant coating, ensuring durability over time. The damping components are precision-engineered to provide consistent performance across all adjustment settings.

The adjustable collars and threaded bodies allow for easy ride height adjustments without compromising the integrity of the suspension components.

Each coilover is assembled with high-quality seals and components to prevent dirt and moisture ingress, maintaining optimal performance even in challenging conditions. The design emphasizes a low center of gravity and optimized damping characteristics, contributing to improved handling, reduced body roll, and a more planted feel on the road or track.
