2026 marks 40 years for Pro-Race Performance Products as an exporter of Harmonic Dampers to the US. Back in 1986 Graham Withers and the team sent the first batch of SFI dampers out of Melbourne, Australia to US customer B&M. Sometime later B&M made a strategy call to only sell their own internally produced products. The remaining stock holdings were purchased by Summit, and things kinda grew from there. At one time Pro-Race was supplying to all the Big-3 crate engine programs (I'm not allowed to tell you if we still do). If it's good enough for them maybe you should consider Pro-Race for your Harmonic Damper needs.

Pro-Race was sorry to hear of the passing of former racer and local Australian motorsport identity Ray Cutchie. Ray was a friend to Pro-Race. Ray worked on projects for Formula Ford and Formula Holden with us in the past. More recently (but still a few years ago) we helped on a harmonic damper for an aviation safety project that Ray was working on. Ray was involved with the famous Allan Moffat Coca Cola Mustang in the 1970s, and ran as a privateer at Bathurst for a number of years in the 1970s and 1980s. Thoughts to the family. RIP Ray Cutchie.
