LSD & Diff Locker Installation in Perth

Traction upgrades set up correctly for road and off-road use

Traction upgrades can transform how a vehicle drives – on wet roads, loose gravel, sand and technical off-road tracks. If you’re tired of one-wheel spin, struggling on climbs, or want more control when towing on slippery surfaces, an LSD or locker may be the right upgrade.

WA Diffs installs limited-slip differentials (LSDs) and diff lockers in Perth, with correct setup to ensure quiet operation and long-term reliability. We’ll help you choose a solution that matches how you use your vehicle: daily driving, work, touring or dedicated off-road use.

Call +61 8 9417 9930 to discuss options for your vehicle and axle type.

LSD vs locker: what’s the difference?

An LSD improves traction by transferring torque to the wheel with more grip. Many drivers like LSDs because they behave smoothly on-road while still providing a noticeable improvement off-road.

A locker (automatic or selectable) can lock both wheels together for maximum traction. Selectable lockers (e.g., air or electric) can be turned on when needed and off for normal road driving. The best option depends on your driving style, terrain and vehicle setup.

Why professional installation matters

Both LSDs and lockers require differential setup work. Professional installation helps avoid:

  • Gear whine from incorrect backlash or pinion depth
  • Premature bearing wear from incorrect preload
  • Oil leaks from seals disturbed during the install
  • Electrical/air line issues (for selectable lockers) due to poor routing or protection

What we consider before recommending a traction upgrade

To choose the right product and setup, we’ll ask about:

  • Vehicle make/model and diff type (front/rear, IFS, solid axle, etc.)
  • Tyre size and whether you plan to go larger
  • Typical use (daily driving, towing, touring, off-road difficulty level)
  • Budget and whether you want selectable control or a set-and-forget option
