⚙️ Technical Specifications

Our plate-type LSDs (Limited Slip Differentials) are crafted from forged nickel-chromoly steel and undergo specialized heat treatments such as Super Sub-Zero (cryogenic treatment). Additionally, some applications are also treated with shot peening and WPC processes to enhance core and surface strength, increase wear resistance, and extend service life.

The use of high-strength materials, combined with these advanced treatments, not only minimizes friction and enhances fatigue strength, but also contributes to weight reduction and improved internal lubrication, thanks to large windows and multi-hole designs.

As a result, our LSDs offer exceptional durability, typically requiring no servicing for the first 2,000 km of special stage use, while delivering consistent and stable performance.

🔩 Main Features

• 12-plate design (most other LSDs use only 8 friction plates)
  → Ensures superior traction and long-term performance, even under demanding endurance race conditions.
• Lightest in its class, weighing only 5.4 kg.
• Equipped with dual-ramp bodies — factory-spec version for this application:
  35/65 & 45/60 ramp angles
  → Other ramp angles available upon request.

🎁 Included Free of Charge

✔ One extra, thicker Belleville (conical) washer, for those who wish to test with higher preload values.

🛡️ Warranty & Reliability

✔ As a testament to our commitment to quality, all our plate-type LSDs come with a 1-year motorsport warranty, covering material and manufacturing defects.

⚠️ Important Reminder

• We recommend using gear oils with shockproof additives or friction modifiers, typically labeled as “LS” (Limited Slip) gear oils, specifically for plate-type LSDs.
• The most commonly used grade is 75W-140 LS.
• During installation, we strongly advise adding gear oil directly into the LSD. Please note that although we apply anti-rust oil during assembly at our factory, it does not provide lubrication.
