Upgrade your 1994 - 2002 Ram 3500 with the LTG 4x4 Air locking differential and experience traction on demand for your next off-road trip.

Key Features for Your Ram 3500 All Series:
  • LTG 4x4 Air Diff Locker: Switchable Traction
  • Positive & reliable
  • Compressed air driven locking mechanism
  • Compatible with existing vehicle mounted compressors
  • Precision-forged gears

  • Superior re-buildable design
  • Push button traction
  • Comprehensive DIY Instructions
  • 6 Year Unlimited Km Warranty


The LTG 4x4 Air locking differential performs as an open differential when not locked, meaning it has no effect on driveability. With the push of a button there is virtually instant locking, and the precision-forged gears lock to provide a 50-50 power split to each wheel.

Suitable for Front and/or Rear applications.

Fitting time generally varies from 5 to 8 hours, depending on application. The LTG 4x4 Air centre replaces the existing, in effect the ring gear or crown wheel is swapped to the new Locker centre.

Comprehensive Fitting Instructions included., as are Carrier Bearings and Seals on many models.

LTG 4×4 Air locking differentials are ‘tuff as nails’ selectable differential lockers for applications where 100% reliable off-road traction is required.

Traction on demand!

LTG 4×4 Air diff lockers performs as an open differential when not locked, meaning it has no effect on driveability and the vehicle drives like normal. With the push of a button there is virtually instant locking, and the precision-forged gears lock to provide a 50-50 power split to each wheel. 100% standard to 100% locked in an instant.

Suitable for Front and/or Rear applications.

The LTG 4×4 Air locking differential uses the traditional method of compressed air feeding through porting in the 8620 steel carrier, to push a locking gear ring onto the underside of one of the 4320 chrome alloy side gears. This ring locks one side gear to the carrier, the other planetary gears cannot rotate – effectively locking the axle shafts together.

However, the LTG 4×4 Air diff lock uses a superior 4 lobe o-ring design in the air ring. These have twice the sealing surface and require less compression to seal – extending the service life.

The LTG 4×4 Air diff locker also has a unique oil return system, where any diff oil that makes its way up to the compressor is returned back to the diff center via an oil return ‘air’ hose.

LTG 4×4 Air requires a vehicle mounted compressor, often referred to as an on-board compressor, to supply instant compressed air to the locking differential. Of course, they are “handy as” for a myriad of other purposes, not least of which is tyre inflation, cleaning air filters and other camping uses. See LTG Single and LTG Twin Air Compressors for details.

The locking mechanisms are tested to the test rig limit of 17,000nm of torque, without failure.

Tuff as nails!

LTG 4×4 Air differential locker centres replace the existing carrier, no matter if it is an OEM LSD or a standard open carrier. They even replace some OEM Lockers. In effect, the existing ring gear or crown wheel is swapped to the new carrier.

Many applications have new carrier bearings included in the kit. The crown & pinion gear relationship does change and the lash needs to be adjusted to finalise the installation. Comprehensive DIY Instructions are included, but seek professional assistance if you are not sufficiently experienced.

All OE recommended oils for the differential are compatible with LTG 4×4 Air diff lockers as are any additives like Teflon, Nulon, STP etc.
