Servicing shock absorbers fitted with internal limit switch buffers presents a specific assembly challenge — the internal buffer must be kept in the correct position during compression of the outer spring, otherwise the buffer can be damaged or incorrectly seated during reassembly. The Govoni GO355 Universal Strut Controller is purpose-designed for the assembly and disassembly of shock absorbers with this limit switch buffer configuration.
The internal buffer is located inside the shock absorber and is responsible for absorbing the shock at the moment the absorber reaches the end of its stroke, ensuring the integrity of the shock absorber under extreme suspension travel. During reassembly, the cylinder stem must remain fully extended while the outer spring is compressed — without the right tool, this is difficult to achieve consistently.
The universal clamp design of the GO355 holds the cylinder stem in extension during compression of the outer spring, which is exactly the position needed for correct internal buffer engagement. The 'universal' designation reflects its compatibility across a wide range of shock absorber stem diameters from 12mm minimum to 28mm maximum, covering the majority of passenger vehicle applications.
Recommended applications: Volkswagen, Audi, Fiat, BMW, Mercedes-Benz, Citroen, Peugeot, Opel, Ford, Nissan, and Toyota — specifically vehicle models equipped with Bilstein shock absorbers, which use the limit switch buffer design that this tool addresses.
Overall product dimensions are 300 x 110 x 290 mm and the tool weighs 2.7 kg.
Govoni is a specialist Italian manufacturer of professional automotive workshop tooling, and the GO355 strut controller reflects the brand's focus on purpose-built tools for specific shock absorber configurations.
