Founded by Australian drag racing champion, Graham Withers, the company is now owned by GAP Manufacturing, currently located in Port Melbourne. PRO/RACE Performance Products is an Australian Company owned by Graham Withers, who was Top Fuel Champion in 1966, 1967 and 1968 driving a “front engine 392 blown Hemi slingshot” which he designed and built himself. After 5 Years of dominating Top Fuel Drag Racing in Australia, Graham retired to establish “Graham Withers Speed Shop” on the main Highway leading south out of the City of Melbourne in 1972.PRO/RACE Performance Products was one of the first specialist manufacturers of SFI Specification #18.1 dampers in the USA market back in 1987. Now widely distributed in USA through a Californian based warehouse, the tried and tested design of PRO/RACE SFI dampers have stood the test of time and have been factory dyno tested and proved to withstand over 18,000 rpm at the SFI test lab. To cater for market needs, several variations have been introduced including the PRO/STREET range of quality “Nodular Iron” bonded OE Style dampers, as well as the NEW PRO/SPORT SFI range for street racers who require an SFI damper at a very competitive price tag. Proud to boast 25 years of damper manufacturing experience, a wide range of distributors and many thousands of satisfied customers, the second-to-none quality of the entire range of PRO/RACE, PRO/SPORT and PRO/STREET dampers are sure to tame the vibration in your engine.

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.

Cliff R from Victoria runs a 392 Hemi in his beautiful little '32 Ford. I love the colour. The motor runs our 64280 Pro-Racer 392 Hemi damper. Our Pro-Racer dampers are SFI certified and good for up to 800HP. Set it, forget it, and just enjoy driving that thing Cliff!
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.

It was great to host Jon and Steve from AH Spares UK at Pro-Race today. They are long time users of our 64295 Austin Healey Pro-Racer dampers - and they're great guys as well.

Tom Kuznicki is a long-time friend of Pro-Race. He, and his brother-in-law Jim Crawford always manned our booths at SEMA and PRI. Sadly, we haven't done much of that since COVID. Here's Tom in his trusty old Mustang. Tom runs a 302 with our 64270 Ford Pro-Racer harmonic damper. Tom was due to be on track with her today. Good luck Tom, and thanks for being a great friend to our business. Hope to catch up soon. I'll be sending over some Tim-Tams!!!!

Ok, so these are not Harmonic Dampers. Graham Withers was having a bit of a clean-up at his home. These parts go back to the origins of the Pro-Street brand and would have been sold through Graham's old Speed Shop back in the day. Pro-Street lives on through the Harmonic Dampers of today as one of three product streams: Pro-Racer, Pro-Sport and Pro-Street. Next year will mark 40 years since the first batch of dampers by Pro-Race Performance Products and we still hold OEM contracts. We must be doing something right!

The 'Pro-Racer' style harmonic damper from Pro-Race Performance Products incorporates a unique rolled-lip design that encapsulates the inertia ring. This super-safe damper easily meets the SFI Spec 18.1 requirements and has been spun up to 18,000 RPM. The 'Pro-Racer' will provide years of protection for your high-performance engine. The 'Pro-Racer' damper is not rebuildable and doesn't need to be. If you don't want to rebuild your damper at regular intervals or play with O-rings, and you just want to get in your car and enjoy driving it, then put a 'Pro-Racer' on your engine. Then get in your car and forget all about it.
