We use the latest technology & have more than 20 years’ experience

So your vehicle is making a noise that it shouldn’t !


Book in with WA Diff Centre for a diagnosis which will consist of a test drive by our technichians and then an inspection of the differential or gearbox.. Depending on what type of vehicle you have, this will usually mean dismantling the component to understand exactly what needs replacing to get it running smooth again.


Our Specialist Services


WA Diff Centre, the only diff specialists in Western Australia

WA Diff Centre is the regional experts on differential reconditioning, servicing & repairs. Whether you require a simple service for your 4×4 differential or a complete reconditioning of a specific diff, the WA Diff Centre has the specialists for the job.

As WA’s repair and diff reconditioning specialists, we will ensure that you choose the right option for both your car and wallet. We are the only company in the WA-area that specialises solely in differential repairs, which means our mechanics are the best in the business and our front of house staff are always friendly and helpful.

The differential has a tough job – it rotates the outside driven wheel on your vehicle faster than the inside driven wheel. This improves the cornering and performance of your vehicle while maintaining your tyre’s maximum usable life. Without it tyres would wear prematurely. This is why it is important to take proper care of it.

Whether it’s supplying replacement parts (new or used) or carrying out rebuilds or conversions on manual transmissions or differentials, we have the solution for you.

We specialise in repairing and rebuilding differentials for all vehicles, including 4x4s and 4WD’s


We offer the best advice, repair and reconditioning services for differentials in WA.

When it comes to repairing differential lockers and LSDs, no-one does it better than the WA Diff Centre. We are the preferred regional specialists and indeed the only differential specialists in Western Australia.

When driving on tough off-road tracks or across uneven terrain, at some point either a front-, rear- or even both front and rear wheels can lift off the ground or loose traction. When that happens the power will always take the path of least resistance, which will be the tires with the least traction. One way to handle these driving conditions is by means of momentum management, which mostly works but requires a great deal of driving skill. The other way is to install a diff locker.

A diff locker locks the differentials, forcing either both front- or both rear wheels to rotate at the same rate, even if one wheel lifts in the air.

If you are looking for a more ‘intelligent’ differential, a Limited Slip Differential (LSD) may be the option for you.  Our expert team will happily advise you on which diff locker is the right one for your vehicle.

At the WA Diff Centre you can be sure of receiving the best advice, repair and reconditioning services in WA.

We offer:

  • Limited slip differentials
  • Auto locks
  • Locking differential
  • Diff locks
  • 4wd lockers


We can fit your vehicle with the right diff conversion

A differential transfers the torque power produced by the engine to the wheels of the vehicle. To keep your vehicle running smooth and efficiently, periodic maintenance of differentials is vital.

Looking for a 9 inch diff conversion to beef up the grunt in your car? We can modify 9″ diffs to suit most makes of cars and 4WDs. As WA’s only dedicated differential specialists, we offer diff repairs and conversion solutions for most makes of cars and 4x4s.

We can provide expert advice and fit your vehicle with the diff conversion that you need to release your car’s true potential.

Our specialist differential team uses the latest equipment for all diff repairs, 9 inch conversions and custom-built differentials.



Whether you’re looking up for a taller ratio for top-end speed or a lower cruise RPM for a more efficient fuel economy, the WA Diff Centre will be able to give you the right advice for your vehicle.

Depending on the type of racing you want to compete in and the type of track you will be racing on, the WA Diff Centre will be able to source the optimum ratio changes for your racing circumstances.
