The 1973 model year was marked by numerous major and minor modifications. One of the main changes was a more angular bumper with a crumple zone at the front.
A crumple zone is intended to minimize the impact of a frontal collision. from the 1973 model year onwards, all VW buses were therefore fitted with a reinforcement bar behind the front bumper, which served primarily as a crumple zone.
Most of the kinetic energy released in a frontal collision is absorbed by the deformation of the crumple zone. This reduces the forces exerted on the occupants.
Obviously, this reinforcement beam must be in good condition, because if a collision has occurred and the beam has not been replaced, it will no longer be able to perform its function as a deformation zone adequately.
It is recommended not to repair the beam, but to replace it completely, as this is the only way to guarantee that it will fulfill its function as a deformation zone in the event of a collision.
Note: This reinforcement beam was originally designed for Brazilian and Mexican Bay Window Buses, and fits perfectly. With a few minor adaptations, it can also be used for German buses. The location of the bumper mounting holes is different. To correct this, you'll need to drill additional mounting holes with threads. Use M8 welding nuts (listed in the options tab).
