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!

For cars with Porsche LSD fitted - Option Code M220 (Locking differential 40 %)

Upgrade the standard Porsche LSD to these Track Day / Race inspired components for improved, performance traction.

Our plates also provide more grip and superior durability, which makes them an absolute must have for everybody who visits the track regularly.

RacingDiffs Performance LSD clutch plates fits OEM Porsche LSD unit without any modifications:

This kit contains:

• 4 x Clutch/friction discs
• 4 x Hardcore dog ear steel plates
• 2 x Pre-load (spherical) shims

Clutches are perforated for better cooling and great viscosity to resist the oil build-up in the holes between dog ear plates. 
It is well known that drilled brake discs improve cooling over solid discs, it is the same with the LSD clutch discs.

The highest quality thermally processed tool steel is used which differentiates our products from any others on the market.

During the final steps of production the clutch plates are coated with special Molybdenum-Ceramic compound which optimizes the best ratio of friction coefficient and durability. This drastically reduces material wear and warping under extreme conditions providing our clutch plates the best possible longevity.

We mastered knowledge in the field of friction materials and coatings, which is the cornerstone of the quality of our products.

All of our clutch plates are thoroughly tested and are currently being used in various racing cars throughout Europe and USA including track, hill climb and rally.

Please Note:
Friction plate upgrade kit should only be fitted by someone with the relevant knowledge and experience.

For Technical Specifications Click Here

The Differential powers both drive wheels under nearly all conditions. With an ordinary open differential (standard on most cars), precious power is wasted during wheel spin under acceleration. This happens because the open differential shifts power to the wheel with less grip, along the path of least resistance. The Differential, however, does just the opposite. It senses which wheel has better grip, and biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel.
