Differential Upgrades & Replacement in Perth

Upgrade traction, gearing and reliability for work and 4WD use

Sometimes the best fix for a worn or damaged differential is an upgrade or replacement – especially if you tow regularly, run larger tyres, or want better traction off-road. The right choice depends on diff condition, your budget and what you want the vehicle to do.

WA Diffs offers differential upgrades and replacement services in Perth, including swap-over centres, traction upgrades like LSDs and lockers, and gear ratio changes. We’ll help you weigh up repair vs rebuild vs replacement so you get a solution that makes sense long term.

When replacement makes sense

A differential replacement may be recommended when:

  • Gears are heavily damaged (pitting, chipping, broken teeth)
  • The diff has run low on oil and multiple components are affected
  • A previous repair has not resolved noise and the gear set is worn

You want a practical swap-over option to reduce downtime

Popular upgrade paths

We regularly help customers upgrade for traction, towing and off-road use:

  • Limited-slip differential (LSD) upgrades for better traction and control
  • Selectable or automatic diff locker installations for serious off-road performance
  • Gear ratio changes to suit larger tyres or improve towing drivability
  • Reinforced or heavy-duty components where appropriate for workload

Setup matters - even on upgrades

Upgrades aren’t “bolt-on and hope”. Traction centres, new gears and replacement assemblies still require correct setup, oil specification and final checks to ensure noise-free operation and long life.

We take the same careful approach whether it’s a daily driver or a touring 4WD: correct parts, correct tolerances, and a clear plan for aftercare.

Next steps

If you’re considering an upgrade, tell us how you use the vehicle (towing weight, tyre size, typical terrain) and what you want to improve. Call +61 8 9417 9930 and we’ll recommend a practical path forward.
