With its proven philosophy of delivering solutions based on excellence in design and manufacturing, Harrop Engineering is a true Australian success story with a rich history dating back more than 60 years

When it was founded by Len Harrop in the inner Melbourne suburb of Brunswick in 1955, Harrop Engineering was a small family business providing general engineering services for the textile and trucking/haulage industries.
As the business grew, Len and Elsa Harrop’s son, Ron, joined after completing his boilermaker apprenticeship. Ron had a strong interest in modifying cars born out of his passion for motorsport.
The combination of Len’s technical knowledge and Ron’s motorsport expertise saw Harrop Engineering grow quickly into a respected automotive engineering and performance parts manufacturer.
Ron’s enthusiasm for ‘making things’ began at an early age. At the tender age of 10, Ron was welding together go-karts in the back shed.
In his teenage years, he fuelled his need for speed by building and racing a variety of cars including a MGTC powered Morris Minor, his much-loved Holden EH and his famous FJ Holden.

Originally bought for $29 from racing identity Norm Beechey, Ron’s FJ, known as “Harrop’s Howler” has become one of Australia’s most loved and recognised racing cars. 
Innovative design combined with on-track success have been the foundations on which Harrop Engineering has built a company philosophy and reputation for engineering excellence.
Over the past 30 years, Harrop has played a part in the success of a variety of top tier Motorsport teams, from Formula One to V8 Supercars and this is a tribute to the precision and design of the performance products the company manufactures.
As capabilities diversified and demand grew, Harrop moved to its current purpose built facility in 2000. Five years later Harrop Casting Technologies was born to supply the necessary quality for the growing portfolio of performance products. This signaled the expansion of the facility located in the inner Melbourne suburb of Preston.

In 2008, the Harrop family sold the business to Adrad – a family owned business based in Adelaide which recognised the value Harrop would add to its already diverse group of companies.
General Manager Heath Moore along with Operations Manager Tim Harrop, Len and Elsa’s Grandson, today head up a young and dynamic management team who are driving Harrop into the future.
At the time of the acquisition, Adrad was already a large player in Australia’s Automotive Aftermarket with a reputation for manufacturing, importing and distributing high quality automotive cooling components.
In addition to the performance components that Harrop added to its portfolio, Adrad designs and manufactures radiator cores in copper, brass and aluminium for both automotive and industrial applications.
Today Harrop operates across several market segments, producing an array of products, intricate components and engineering solutions for both the automotive and industrial sectors.
“Harrop Engineering is a modern, world-class operation committed to technical excellence in total component manufacturing,” Harrop Engineering Australia General Manager, Heath Moore, said.
“Our core range of proprietary products for the Automotive aftermarket industry include Superchargers, Manifolds, Brakes, Differentials and Cooling for both Australian delivered and global vehicle platforms including the Toyota 86, Toyota Tundra, Nissan Patrol/Titan range and the Dodge Ram.
“Driven by a commitment to quality and performance, our team’s primary focus is to improve the safety, reliability and durability of our engineering products.”

Using ‘state-of-the-art’ computerised CNC equipment driven by a commitment to quality, Harrop is continually striving to improve the accuracy and consistency of its manufacturing processes. Modern simulation tools produce virtual products prior to prototype validation and production builds, enhancing the integrity of the final product.
“Harrop’s quality-assurance system is accredited by world standards. This, combined with our advanced product quality planning system, allow Harrop to deliver an outstanding level of service to a broad customer base ranging from global OE vehicle manufacturers to performance enthusiasts,” Heath explained.
Harrop and Eaton – a positive partnership
Sharing a synergy for Research and Development, Harrop has achieved the enviable status of licensed Master Distributor for Eaton Corporation. This allows Harrop to work closely with the US Company and utilise its technology in the manufacture of Positive Displacement Superchargers and Traction Control Products for low volume applications and OEM customer programs like Ford, Holden, Toyota and Lotus.
A strong future ahead
Heath says Harrop’s robust development pipeline for Supercharger, Differential, Brake and Cooling product is securing future growth and attracting new customers.

“A key challenge for contemporary manufacturing companies with a diverse portfolio such as Harrop is the ability to remain dynamic and agile. This is the cornerstone when projecting beyond 2019 and fundamental to our sustainability and growth,” he said.
“Remaining agile transcends machining equipment for the business and includes product development as our alertness to opportunities within the automotive industry remains high.
“Vertical integration provides Harrop with a strong competitive advantage, starting with the company owned foundry, Harrop Casting Technologies, coupled with Harrop’s engineering design capabilities and quality certified manufacturing.
“As a result, we offer an all-inclusive solution to customers that provides them with a competitive edge through our unique mix of competencies, which include 3D CAD Modelling and analysis, tooling design and production, prototyping, CNC machining, aluminium casting, assembly and quality assurance systems.”
Heath states that Harrop is solution focused, whether in regard to its own proprietary performance products or customer programs.
As long-term AAAA Members, Harrop values the opportunity to collaborate with industry partners and peers. In addition, its membership provides it with insights to help it stay abreast of industry developments, flag challenges and identify new opportunities.
There is no doubt that the team at Harrop are true innovators. Having recently incorporated in the USA and established a facility in Dayton Ohio, the next chapter of the Harrop story is about to be written as they begin to capitalise on opportunities for export market growth.
