3J Driveline NXG 

Limited Slip Differentials 

 
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 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, which 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. 
 
We stock an extensive range of NXG LSD's to fit the most common applicatoins, and are constantly adding new lines to our range. The NXG inernal design gives you the flexibility to fine-tune its set up should you choose to change the plate and ramp angle configuration.

Choosing The Right Unit For You  

 
 
Choosing the right diff for your car is very much a case of horses for courses. If you use your car for spirited drives to and from a local car show, it’s pointless running a plate-type differential with 45/45 ramp angles and lots of pre-load. In reality, because our NXG can be fine-tuned, you would be okay with a fast road plate-type unit.  
 
The question that you ultimately have to ask yourself is:  
Do I want my rear wheels to lock together when I ask them to? 
If the answer is: Yes, you need a plate type diff. 
If the answer is: No, then maybe you don’t need a limited slip diff at all. 
If the answer is: no, but I would just like a bit more traction out of the corners for my Sunday morning B-road hacks in my mildly-tuned car. A torque biasing diff is for you. 
If the answer is: no, but I’ve got lots of power and I want it to be predictable when it gets out of shape. You need a plate type diff like the NXG. 
In general, a torque biasing diff unit is better suited to fast road front-wheel drive applications, but we have a number of customers that use them in 'fast-road' rear-drive vehicles. 
Experience has shown that people may opt for a torque biasing differential initially, mainly because it is a less-expensive unit. However, the nature of modifying cars is that things progress, power figures increase, and the user ultimately finds themselves upgrading to a plate-type unit. So before committing to buy, consider whether you’re likely to continue modifying your vehicle and whether, perhaps, an NXG Performance unit, with a fast-road set-up, might be better suited to you.
