EXTREMEspec MT82 Solid Output Shaft Kit

The Ultimate Fix for Defender 2.4 / 2.2 TDCi Worn Output Shafts

On Defender 2.4 and 2.2 TDCi models, one failure is almost guaranteed sooner or later:
the splined coupling shaft between the MT82 gearbox and the LT230 transfer case wearing out and destroying drive.

From factory, Land Rover assembled the coupling 100% dry, with no grease at all — and that decision causes premature spline wear and eventual spline failure.

Common symptoms include:

• Clunking when taking up drive

• Clunking on deceleration

• Intermittent or sudden loss of drive

• In advanced cases: complete drivetrain failure

For years, LOF supplied the updated genuine kit (now supplied with EP grease). After moving more than 500 units, it became clear: there was room to engineer a better, permanent fix.

Introducing the LOF EXTREMEspec MT82 Solid Output Shaft Kit

Developed over 2 years with industry specialists, this is the definitive, engineered-for-life solution to the MT82 coupling problem.

Why this design is superior

Simple:
We’ve removed the failing coupling entirely.

Instead of a two-piece arrangement with a separate coupling that wears out, the EXTREMEspec kit uses a one-piece solid shaft, following the proven layout of earlier Land Rover drivetrains.

The shaft is secured using a central M12 draw bolt, ensuring a positive, constant clamping load against the back of the MT82 gearbox.
No movement.
No fretting.
No spline wear.
No weak points.

This is the fix the Defender should have had from factory.
