Newcastle Gearbox and Diff

Matthew Chandler and Mark Kent began the business in 1995. When we began there were only 3 employees in total.

Mat and Mark struck up a good union with Mat running Sales and Mark running the workshop. This still applies today.

We have grown over the years and now employ 10 staff. Matthew and Wayne are at the front taking care of customer service and administration, while Mark co-ordinates the running of the workshop floor and 7 staff.

Wayne Fuller is the business manager and has been with the company since 1997. Matthew and Wayne’s combined parts interpreting and locating experience exceed 40 years. The combined mechanical experience of the team exceeds 50 years.

Our original location was situated around the corner from our current premises. It was 300 square metres in size. We quickly outgrew it, and in 1998 we purchased our current building, just over 1000 square metres in size. We had the shop equipped totally separate to our old one, which meant we could literally close the doors, walk our tool boxes around the corner on a Friday and open for business in our new shop the following Monday.

Our equipment includes 7 hoists that can handle up to 5 tonne capacity and what we consider to be a complete range of specialty tools for the specialised field we cater for.
