Superior Engineering Track-Corrected Diff Upgrade

Designed and manufactured in Australia, the Superior Engineering Track-Corrected Chromoly Diamond Diff Housing sets the benchmark for strength, precision, and reliability in 70 Series LandCruiser axle upgrades.

Built to correct the factory narrow rear track found in VDJ70 Series LandCruisers, this housing is manufactured 100mm wider than OEM to perfectly align the rear track with the front — improving stability, handling, and load distribution both on and off-road.

At its core is Superior Engineering’s unique 830MPa Chromoly wide-diamond centre section, reinforced with internal gussets and integrated with 90mm OD, 13.5mm thick axle tubes. This design eliminates the need for external bracing while delivering superior strength and increased ground clearance over competitor housings.
