Original spare parts better safe than sorry! In the worst case scenario, all it takes is a non-functioning fifth wheel coupling locking mechanism, a bolt that is unable to stand up to sufficient pressure, or even just a defective screw to cause an accident. That is why the German Federal Motor Transport Authority and legislative authorities demand the mandatory use of original spare parts for components subject to type approval, such as fifth wheel couplings and towing hitches. Components from JOST and ROCKINGER connect tractors and trailers with one another and must be able to withstand the toughest of loads. That is why they are considered to be safety-related products that must hold type approval in accordance with 22a German Road Traffic Approval Directive (StVZO) or ECE Directive R55-. The approval is issued by the German Federal Motor Transport Authority (Kraftfahrt-Bundesamt), which imposes strict requirements on the manufacturers from development to quality control during production. Stress tests are performed on all components and documented under the constant supervision of the KBA. Any modifications to parts result in renewed testing and documentation, including supplements to the homologation. Original spare parts kits from JOST are now delivered in unmistakeable packaging with a counterfeit-proof hologram. This ensures that you are really receiving JOST quality! Producers and suppliers of replica parts do not have the necessary expertise on how the parts interact, nor are they subject to checks by the authorities responsible. That is why there is no alternative to original spare parts from the manufacturer! CAUTION The installation of any spare parts that do not hold type approval in accordance with 22 of the German Road Traffic Approval Directive (StVZO) on articulated vehicles and towing hitches is forbidden in Germany! Frankfurt Regional Court found (file reference 2- O 654/12) that wearing and spare parts for components subject to type approval in accordance with 22a Para. 1 Clause 6 (StVZO) may only be sold by the holder of the type approval. This means that dealers and workshops which sell or install such items as well as the vehicle operator are fully liable for the consequences. Even offering non-original spare parts for connecting systems subject to type approval for sale is punishable. More and more European countries demanding homologation in line with the new ECE Directive R55- are adopting this legal concept in their own national road traffic approval directives, in the same way as Germany's (StVZO).
Wear limits easily checked Fifth wheel couplings and king pins are both subject to a certain amount of wear, depending on their operating conditions. This can be discovered when backlash towards the direction of motion is noticeable. Too much backlash can lead to surging and can cause a threat to safety on the roads and damage to the fifth wheel coupling, the mounting plates, and the chassis. 2" fifth wheel and king pin 3.5" fifth wheel and king pin 2" 3,5" New Ø 73 mm min.
