Rear lsd clutch plate replacement pack. Porsche 958 Cayenne
Code: 95835040690
Rear differential clutch plate replacement pack. 

racingdiffs

Fits:
Porsche 958 Cayenne - 2011 to 2018
For cars with Option Code - P1Y1 (Differential lock, rear, centre differential lock)

Many Cayenne owners report 'crunching' sounds and vibrations from the rear axle, without any solution from the local dealers. The dealers claim all those sounds coming from the rear differential 'normal' but such noise is certainly not normal.

This problem was studied and it was concluded it comes from a worn limited slip differential (LSD) clutch plates. As these aren't available as a spare parts, we produced our own Rear LSD clutch replacement pack.

Our production technology is well-tested and approved by California Motorsports, a company specialized in rebuilding Porsche transmissions.

Instead of purchasing a super-expensive new rear differential for your Cayenne, which will eventually break down as well, you can repair yours. Not only that, with this LSD repair set, you will solve this problem for good.

What is LDS ramp angle?
Ramp angles primarily determine the behaviour of the LSD under acceleration and braking. They are often referred to as 1 way, 1.5 way, and 2 way, these terms refer to when the differential locks. 

LSD Multi-variant Ramp set (Pressure plates) provides 3 different ramp angle positions:

30°/30°
30°/60°
50°/65°

Pressure plates are made from a forged material for maximum strength
High-precision CNC finish provides a Plug & Play installation
Chemically heat treated for high durability and wear resistance

Why is the Multi-variant Ramp set a must-have for all types of racing ?
This set combined with our Performance clutch set is the ultimate LSD performance upgrade. It allows you to adjust your differential from 25% up to 100% lock in 2 ways or 1.5 ways. By altering the ramp angle setup, you control how fast and effectively the differential locks. You don't need several differential as adjusting this one according to your track requirements will guarantee success.

How to tell if your differential bearings need replacing?
Characteristic noise from differential/transmission occurs during acceleration and coast (engine breaking). To distinguish differential bearing noise from wheel bearing noise steer left-right like you are warming up the tyres for a race.

If the noise changes its intensity then it is a wheel bearing. If intensity of the noise remains the same, this means the differential bearings need to be replaced.

RacingDiffs Components are OEM quality.

Front differential set also fits the following models:
Volkswagen Touareg 2002-2010 (all engines with 6-speed gearbox)

Revitalize Your Vehicle's Performance:
RacingDiffs introduces the ultimate solution to restore the original performance of your Porsche 991 and 991.2 GT3/GT3 RS. Our LSD clutch pack is meticulously designed to rejuvenate your car when factory plates are worn out, eliminating the need for a complete transmission replacement.

Avoid Unnecessary Expenses:
Porsche’s factory setup doesn’t offer replacement plates, compelling owners to replace the whole transmission—an immensely costly and unnecessary endeavor. With RacingDiffs, replace only what’s needed, ensuring other flawlessly working gearbox components remain undisturbed, saving you tremendous costs.

Superior Molybdenum-Ceramic Friction Layer:
Unlike the factory plates that come with paper-like friction material, RacingDiffs clutch plates are fortified with a superior molybdenum-ceramic friction layer. This enhancement ensures a robust and enduring performance, substantially outperforming the conventional materials used in standard plates.

Race-Proven, Heavy-Duty Technology:
Embrace the confidence of race-proven technology. Our LSD clutch pack is built for heavy-duty performance, providing a resilient and reliable option for those who require the very best in racing technology. Equip your Porsche with components engineered for durability and exceptional performance under rigorous driving conditions.

Kit Includes:

  • High-Performance Clutch/Friction Discs x 6
  • Heavy-Duty Dog Ear Steel Plates x 7

Innovative and Efficient:
The clutch discs are strategically perforated for optimal cooling and viscosity, preventing unwanted oil build-up, and ensuring consistent and efficient operation under various driving conditions. Trust in a clutch pack that exemplifies innovative engineering and ultimate performance.

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