As far as impact protection is concerned, one can disagree. An example: the Dune Fighter has been extensively tested by us. It is possible to use a bumper to prevent damage in a frontal crash. Of course, the best damage prevention is good control of the vehicle, but in most cases this cannot be permanently prevented. The bumper can be screwed to the front end of the vehicle. Existing fittings can be used for this purpose. In the event of a crash, however, these screws also absorb the energy and transfer it via their thread. For the Dune Fighter, the screws of the differential housing and those of the wishbone mounts can be used. In the standard model, their threads are only made of plastic and can usually only withstand the load from a built-in front bumper for a very short time. The problem can be solved for the wishbone brackets as well as for the differential housings by robust aluminium parts, because these have extremely strong metal threads.

Without a bolting method that is capable of absorbing the energy of an impact, it is therefore not advisable to use an otherwise very sensible front bumper, as it is usually a short question of time until the front end of the vehicle no longer holds together.

You want to protect the chassis with a front bumper, which bends with hard impacts and entails an increased maintenance effort, and parts of the axle. The latter are so exposed in the front that an impact with the wheel often results in the breakage of a wishbone or wishbone bracket, the wishbone retaining pin and the wheel axle. A bumper can reduce the risk of such damage. Of course, a high-quality suspension also helps.
