Product Details
You get a set of AST 5100 Series True Coilovers in this package. These are designed for the Ford Focus and let you adjust both rebound damping and ride height. If you want to dial in your car's handling for better grip and a more predictable feel, these are a solid option. They come with springs and are made to work with your car's original top mounts.
The 5100 series uses a monotube damper design. This means a larger piston inside controls the rebound adjustment, giving you more responsive valving without aeration or foaming. AST builds these dampers to handle higher pressures, which helps performance when you need it most. Plus, they're rebuildable at a certified AST service center if any issues come up.
