Construction & Design

AST Lowering Springs are crafted from high-quality spring steel, chosen for its excellent strength and fatigue resistance. The springs are precisely wound using Wafios coiling machines, which ensure uniform coil spacing and consistent spring rates across every unit. This precision manufacturing process results in springs that deliver predictable handling characteristics and a smooth ride.

The progressive design means the springs become stiffer as they compress, allowing for comfortable daily driving while providing firm support during aggressive cornering or heavy loads. This balance of comfort and performance is a hallmark of AST’s engineering approach.

Installation & Fitment

These lowering springs are designed as direct replacements for the factory springs on Jeep Grand Cherokee models from 1993 to 2004, including both the 1993–1998 and 1999–2004 model years. Installation is straightforward and can typically be completed with standard suspension tools. No cutting, welding, or additional modifications are necessary, making it an ideal upgrade for both professional installers and experienced DIY enthusiasts.

For best results, it is recommended to have a professional alignment performed after installation to ensure optimal handling and tire wear.
