Why Choose a 3J Driveline NXG Performance LSD?
The NXG Plate-type limited slip differential is designed, manufactured and assembled right here in the UK.
It has been engineered to be the strongest, most progressive and versatile LSD unit in the market place today.
The NXG Performance bevel and planet gear pack, with its big, strong tooth profile, gives not only a smooth mesh, it also all but eliminates the rattle and excessive back lash often associated with plate-type LSD's. Whilst the plate pack always runs on a minimum of 8 active surfaces (even in our lighter pre-load settings) to give maximum surface-to-surface area contact during use.

Because your differential will be assembled by one of our experts here in the UK, we can set it up to suit your exact requirements.

We recommend that you check for correct fitment before purchasing.
