Key Features

The AST 5100 Series Coilovers incorporate several advanced features that set them apart from standard suspension components:

• Customizable Ride Height: The coilovers allow for precise ride height adjustment, enabling you to lower your vehicle for a more aggressive stance or raise it for increased ground clearance. This flexibility helps optimize handling and aesthetics.
• Performance-Oriented Design: Engineered for enthusiasts who want better control and feedback, these coilovers improve overall handling, reduce body roll, and support more aggressive cornering.
• Universal Fitment: Designed specifically for the Nissan 240SX from 1989 to 1994, ensuring a direct bolt-on installation with no need for modifications.

Construction & Design

The AST 5100 Series Coilovers are constructed with precision and durability in mind. The shock bodies are made from high-strength steel, coated to resist corrosion and wear. The monotube design provides superior heat dissipation and consistent damping performance, even during extended spirited driving sessions. The adjustable components are CNC-machined for precise fitment and smooth operation.

The coilovers feature a lightweight yet robust construction that maintains structural integrity while reducing unsprung weight, which contributes to improved handling and responsiveness. The adjustable collars and damping mechanisms are designed for ease of use, allowing you to quickly dial in your preferred settings without special tools.
