About Us

Terry Hay’s Shock Treatment began its specialised, motorcycle suspension operation in 1996. Motivated by performance and a quest for knowledge, Terry travelled to Los Angeles, California to attend the Race Tech “Technical Edge” suspension Seminars. Returning several times to study advanced theory and continually further his education on the subject. Today Terry and Shock Treatment have proven to be Australia’s premier suspension outlet. We are the first for solving design issues with stock suspension as well as industry leaders in innovative concepts and ideas.


In a non-regulated industry where untrained people are allowed to call themselves “Suspension Tuners”, Shock Treatment has attempted to raise the standard through education. We regularly host training seminars in Australia featuring Paul Thede from Race Tech USA. Paul is one of the most credentialed people in the suspension industry today. Sadly some refuse to be educated, leaving pitfalls for the unwary.

Remember …”Not all suspension tuners are created equal”
