3J Driveline NXG Porsche 915 LSD Diff


3J Driveline NXG Porsche 915 LSD Diff

Pretty much the ultimate progressive diff with the smoothest lock on the market today, transforms your ride into an ultimate tractive car.

We can refurbish your diff and install you new LSD for you, this includes inspecting your components, blasting your parts and coating where required and replating your bolts. Your diff will come back in as new condition.

3J LSD's are very customisable and if you call us and let us know your specifications we can supply you a customised LSD for no extra cost.

Choose from 11 different ramp angles:

40/40 - 70/70 - 40/60 - 20/80 - 50/50 - 45/50 - 80/20 - 50/45 - 15/60 - 60/40 - 60/15

Custom Preload available: - Select Custom and inclue a note in the checkout with the preload required.


A general replacement for a road car this will be setup with 50/90 ramps and 30lb.ft preload.

A good track car will require 30/90 or 40/90 ramps with 50-70lb.ft preload.

A nice rally setting would be 30/60 or 30/90 ramps with 60-80lb.ft preload.

For Drag racing we find 30/90 ramps and up to 100lb.ft for a dedicated car is a good start.

All NXG Ramps have 2 sets of angles on each diff, so if you order one you will be able to swap to the other with a simple diff rebuild. The associated ramps are as follows:

30/90 - 40/90
45/45 - 50/90
35/45 - 30/30
20/75 - 30/60
40/60 - 20/80
