How do I adjust the ride height and rebound damping?

Ride height is adjusted by threading the lower spring perch up or down on the shock body. Rebound damping is adjusted using the knob at the top of the damper, with 12 distinct positions available.

What is the benefit of a monotube damper design?

Monotube dampers use a large piston to control rebound damping more precisely. This design prevents aeration and foaming, which results in more responsive valving and consistent performance, especially under demanding conditions.

Can I use my original top mounts with these coilovers?

Yes, these coilovers are designed to work with your vehicle's OEM top mounts. This simplifies the installation process and helps maintain a comfortable ride configuration.

Product Details

Worn-out suspension components cause poor handling and an uncomfortable ride. The AST 5100 Series coilovers are a direct fix for your 2001-2004 Mercedes-Benz SLK230, offering a balanced setup for daily driving.

These coilovers use a non-inverted monotube design. Monotube dampers have a large piston, which helps control rebound damping more precisely. This design prevents aeration and foaming, leading to more responsive valving and consistent performance. The front dampers are a coilover setup, while the rear maintains a divorced setup similar to OEM, contributing to a more comfortable ride without sacrificing road balance. They include springs and are made to work with your factory top mounts. The rear springs have vehicle-specific, fixed rates determined through extensive development.
