Mono tube low speed damper
The design and operation of the 28 series racing damper is a unique proof of KONI’s reputation as the leader in the field of damper technology.
They are specifically designed for competition purposes and offer full adjustability while fitted on the car. Their precision adjustment mechanisms allow maximum control over the damping forces generated, especially in the low speed damping range.
To achieve this, the 2812 series do not rely on the commonly used needle valves. Instead, a superior and advanced adjustment cartridge controls the opening and closing of valve loaded ports. Positive lock detents assure that each port can only be either open or closed. The result is that the cartridge will always accurately reproduce a set of eight pre-programmed damping curves.
Various cartridges are available, each with its own set of characteristics. A pair of cartridges is housed in the main piston, one for bump, one for rebound. Together they can modify any given basic valving in 64 different ways. By having all forces generated by the piston assembly, the control of the damper over the suspension is instant and precise, decisive and smooth.
A separate bulky reservoir is not needed and the installation can be kept simple, compact, lightweight and clean.
Drivers like the 28 series because they feel a real difference between adjustment steps. Mechanics and race engineers appreciate the user friendliness and apparent "simplicity" of the dampers that make them so easy to work with. And Buyers like their price / quality ratio.
Long body series
Commitments to continuously improve the motorsport products have resulted in the next level of products. Hence KONI developed the 2812 Long Body series race damper. They are an extension to the 2812MKII Series, having a range of strokes from 114 up to 224 mm.
The 2812 Long Body is designed with an aluminium body and end cap. Both top mountings and lower mountings are designed to fit 1/2" ID bearings. Two top mounts are available, with the difference being the adjustment window position at 0° or 90°.
