Performance Racing clutch kit double disc flywheel Car Parts Lightweight for Nissan Patrol TB48 TB45 Y61 damage race parts

Why Upgrade the Clutch?

• 
  

  Significant Power Increase: After modifications like turbocharging, supercharging, or deep engine tuning, torque output can far exceed the stock level.

  
  

• 
  

  Extreme Off-Roading: Frequent rock crawling or mud extraction requires prolonged, high-intensity clutch slipping, generating immense heat.

  
  

• 
  

  Heavy Towing: Regularly towing large caravans or trailers puts severe stress and thermal load on the clutch system.

  
  

• 
  

  Improved Feel/Performance: Pursuing a more direct engagement point, lighter pedal effort (less common), or greater durability for competitive use.

  
  

Upgrade Directions and Key Component Selection

1. Performance Pressure Plate

• 
  

  Enhanced Diaphragm Spring Pressure Plate:

  
  

• 
  

  Function: Maintains the original hydraulic system but uses a stronger diaphragm spring to provide greater clamping force, preventing slippage.

  
  

• 
  

  Characteristics: Pedal feel will be heavier than stock, but engagement is sharper and more defined, with better resistance to heat fade. This is the most mainstream and versatile upgrade choice.

  
  

• 
  

  Multi-Spring/Coil Spring Competition Pressure Plate:

  
  

• 
  

  Function: Replaces the single large diaphragm spring with multiple smaller coil springs for more even pressure distribution and stability under extreme conditions.

  
  

• 
  

  Characteristics: Pedal feel is extremely heavy. Typically used only for professional racing or thousand-horsepower builds, and is very unfriendly for daily use.

  
  

2. High-Performance Clutch Disc (Friction Material)

• 
  

  Organic/OEM Replacement: Comfortable, but prone to slipping and burning under extreme conditions. Suitable only for stock replacement.

  
  

• 
  

  Kevlar/Aramid Fiber: Ideal for serious off-road upgrades. Heat-resistant, wear-resistant, thermally stable, and less abrasive to the flywheel than metallic materials, with a relatively smooth engagement. The top choice for balancing durability and drivability.

  
  

• 
  

  Ceramic/Metallic Sintered: Can withstand extremely high temperatures and pressure, with superior resistance to heat fade. However, they often require high RPM and heat to operate optimally, are highly abrasive to the flywheel, and may engage harshly or be noisy when cold. Common in drag racing.

  
  

• 
  

  Hybrid Materials: Combine the advantages of various materials, offering a compromise between performance and durability.

  
  

3. Lightweight Flywheel

• 
  

  Function: Reducing flywheel weight improves engine responsiveness, allowing faster revving. This can be beneficial for precise throttle control during off-road maneuvers.

  
  

• 
  

  Trade-off: Reduces engine rotational inertia, requiring more precise throttle control during low-speed crawling and potentially affecting idle stability with accessories like A/C. For Patrols focused on low-speed crawling or heavy loads, choosing a stock-weight or slightly lighter flywheel is a safer bet.

  
  

4. Reinforced Release Bearing

• 
  

  Utilizes bearings that are more heat-resistant and wear-resistant to handle the increased load and potential heat from a stronger pressure plate.
