The Bilstein B6 1985 Volkswagen Golf Base Front 30mm Monotube Strut Insert is a high-performance suspension upgrade designed specifically for 1985 Volkswagen Golf Base models. This strut insert is constructed from a single tube of high-strength steel, providing superior strength and durability compared to traditional twin-tube designs. The monotube design also allows for greater control of the internal gas pressure, allowing for a more consistent damping performance throughout the entire suspension travel. This strut insert is designed to improve handling and ride quality, while also providing improved performance on the track.
