Benefits for the client

The JOSAM straightening equipment makes it possible to effectively and qualitatively repair damage to vehicle frames and chassis instead of replacing these components. This means that there is a significant economic advantage for all concerned.

Our wheel alignment systems ensure correct axle and wheel alignment, which reduces both fuel consumption and tyre wear. It also improves driving safety and comfort.
JOSAM’s wheel alignment systems are used all over the world by

  • OEM workshops
  • Independent workshops

Training for users of JOSAM products is another core activity.
