Legendary Adjustability

Trusted by driving enthusiasts for decades, these dampers deliver the precision, control, and adjustability that made KONI a household name in motorsports and on the street. Whether you're navigating daily commutes or attacking winding roads, KONI Sport dampers provide razor-sharp handling, reduced body roll, and a tailored ride feel, all without sacrificing everyday comfort. Built to last and easy to install, they let you fine-tune your drive on your terms.

External Adjustable Design

No tools. No downtime. Just twist the rebound knob, conveniently located under the hood or in the trunk, to dial in your ideal balance of comfort and control. Adjust on the fly for touring, autocross, or spirited drives, often without removing the wheel or strut.

Best Match for Performance Lowering Springs

The KONI Sport series is our highest-performing damper for street and track-inspired builds—specifically engineered to pair with high-performance lowering springs. For drivers pushing the limits, this is the ultimate KONI upgrade. Available individually or as part of complete Sport Kits for a perfectly matched suspension package.

Quality OEM Fitment

Each KONI damper is meticulously designed with OE-quality mounting points and geometry to ensure installation is seamless. No cutting, fabrication, or aftermarket alignment corrections are needed when using a KONI product.

Twin-Tube Construction

Sport uses a twin-tube design, with an inner and outer cylinder that work together to manage oil flow, providing consistent, controlled damping while isolating the vehicle body from road imperfections. Paired with its external adjustment style, drivers can fine-tune rebound forces on the fly, giving more control over handling and cornering performance.
