Design & Manufacturing

Our plate-type limited-slip differentials are manufactured from FORGED Nickel-Chromoly steel and subjected to advanced heat treatments such as Super Sub-Zero / Cryogenic treatment.

In addition, all critical components undergo shot peening and WPC treatment, significantly improving:

• Core and surface strength
• Wear resistance
• Fatigue life

The use of high-strength forged material, combined with an optimized internal design featuring large windows and multiple oil holes, results in:

• Reduced internal friction
• Improved internal lubrication
• Lower overall weight
• Enhanced thermal stability

As a result, our LSDs deliver stable and predictable performance with exceptional durability, typically requiring no servicing during the first ~2,000 km of special stages under normal competition use.

Technical Specifications

Plate-type LSD with 12 friction plates
→ Unique configuration on the market for this application

• Ultra-lightweight design: approx. 4.45 kg (lightest in its class)
• Stable preload values, even during long endurance races
• All our plated LSDs feature dual ramp bodies.
  Factory ramp configuration for this application: 35 / 65 & 45 / 60
• Other ramp angles are available upon request.

Additional Parts Included (Free of Charge)

✔ Extra thicker Belleville / conical washer, allowing experimentation with higher preload values

Installation note:
Crown wheel bolts must be tightened to the manufacturer’s specified torque as indicated in the factory repair manual.
We strongly recommend using a high-strength threadlocker, such as: Loctite 271 (red)

For maximum security: Loctite 270 / 2701 (green)

Warranty

As proof of our quality and reliability, we offer a 1-year motorsport warranty covering material or manufacturing defects across our full range of plate-type LSDs.

Important Reminder – Gear Oil

For correct operation and maximum service life, we strongly recommend the use of LS (Limited Slip) gear oils specifically formulated for plate-type LSDs.

Typical recommended viscosity: SAE 75W-140 LS

Only oils with LS specification must be used when a plate-type LSD is installed

It is also recommended to pre-lubricate the LSD with gear oil during gearbox assembly.

⚠️ Note: Although an anti-corrosion oil is applied during factory assembly, it does not provide lubrication.
