Upgrade to NXG Ultimate for Peak Performance...

For those seeking the highest level of performance, opt for our NXG Ultimate Upgrade by selecting "Yes, please" in the dropdown box below. This upgrade includes our Sintered Plate Pack, which reduces noise significantly and enhances both performance and service life.

Why Choose 3J Driveline’s NXG Performance LSD?

Proudly Engineered in the UK: Designed, manufactured, and assembled in the UK, ensuring precision and quality.

Strong & Progressive Design: Our NXG Plate-Type LSD features a robust bevel and planet gear pack with a large, strong tooth profile. This results in a smooth mesh and nearly eliminates the rattling and excessive backlash that often plagues other plate-type LSDs.

Maximum Contact Area: The plate pack operates with a minimum of 8 active surfaces, even at lighter pre-load settings, to provide maximum surface-to-surface contact for optimum performance.

Each differential is carefully assembled by our in-house experts, and we offer full customization options to suit your specific requirements.

Fitment & Installation...

While our LSD is designed as a direct replacement for the original part, we recommend checking for correct fitment before purchasing. Due to variations in original manufacturing tolerances, some modifications to the original casing or housing may be necessary during installation.

Upgrade your Porsche 996 Turbo with a 3J Driveline LSD and experience the ultimate in performance and precision!
