Design & Manufacturing

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

Additionally, all internal components undergo shot peening and WPC treatment, significantly improving core strength, surface durability, wear resistance, and fatigue life.

The use of high-strength materials, combined with optimized internal geometry featuring large windows and multiple oil holes, results in:

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

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

Technical Specifications

• Plate-type LSD with 16 friction plates
  → The only LSD on the market with this configuration
• Ultra-lightweight design: approx. 5.6 kg (lightest in its class)
• Stable preload characteristics, even under endurance racing conditions
• All our plated LSDs feature dual ramp bodies.
  The factory specification for this application is:
• 35 / 67.5 & 35 / 90 ramp angles
• Other ramp configurations are available upon request.

Included Components

• High-tensile ring gear / crown wheel bolts, steel grade 12.9 (included free of charge)
• Additional thicker Belleville / conical washer for users seeking higher preload settings

Installation Notes

• Crown bolts must be tightened to the manufacturer’s specified torque as per the workshop manual.
• We strongly recommend the use of high-strength threadlocker:
• 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 and manufacturing defects on our entire range of plate-type LSDs.

Important Reminder – Gear Oil

• For optimal performance and longevity, we strongly recommend using LS (Limited Slip) gear oils specifically formulated for plate-type LSDs.
• Typical recommended viscosity: SAE 75W-140 LS
• Only oils with LS specifications must be used
• 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.
