3J Driveline NXG Plate-Type Limited Slip Differential

From fast-road and track day to all-out race or drift applications, the 3J Driveline NXG Plate-Type Limited Slip Differential can be set up exactly to suit your requirements. The amount of pre-load and ramp angles are fine-tuned for each application, affecting how the differential locks under acceleration and braking.

Plate-type Limited Slip Differentials have a cross pin which rides up a ramp on the bevel gear, applying pressure to the friction plates and locking both sides of the differential together. For example, a shallow ramp angle of 25 degrees will allow the cross pin to slide up the bevel gear easily, applying more locking force to the differential. Steep 90-degree ramp angles prevent any additional load from being applied, relying on pre-load to lock the differential instead.

Pre-load is used to set how much force is applied to the friction plates before any engine torque is applied to the differential. More pre-load requires less effort to lock the differential, locking it sooner. Due to how plate-type differentials lock, slight noise and wheel judder can be expected at low speeds.

Accel/Decel Ramp Angle (degrees) Preload (lb-ft) Notes
Track 40/90 65-75
Race 30/90 65-75

We Can Install This For You

We've designed our workshop services to be easy to book and pay for online. To book, you'll need to pick a date and time that suits you and then add the products you want to be installed.

Each workshop product is a labour price only. We've recommended some products on each page, but you can also find other compatible products at the bottom of the page. This way, you know exactly what product you're getting and how much its costing to fit.

Add both the workshop service as well as the product to be installed to your basket and proceed to the checkout. Once there, you can confirm your dates and process the order. Occasionally, some products may require confirmation, when this happens we will make sure we have the stock to fulfil the install and get back to you within 1 working day.

If you have any questions, want a bespoke installation or would prefer to book over the phone, give us a call on +44 (0) 203 795 0515 or send us an email at [email protected]
