Construction & Design

The KONI Heavy Track shock absorber features a twin-tube design that separates the hydraulic fluid and gas chambers, ensuring smooth and consistent damping response. The low-pressure nitrogen gas charge minimizes cavitation and foaming inside the shock, which can degrade performance over time. This design enhances shock longevity and maintains ride quality under heavy use.

Constructed with high-strength steel components and precision-engineered internals, the shock absorber is built to endure the stresses of off-road driving and heavy-duty applications. The vibrant red powder coat finish not only adds a distinctive look but also protects the shock body from corrosion and environmental damage, extending the service life of the component.
