Supplier's note

1. Technical Breakthroughs:

   • Aerospace alloy pistons (Pro Model) reduce thermal expansion by 25% compared to steel, preventing clutch slippage.
   • Diamond-tooth geometry increases friction coefficient by 20%, outperforming flat-tooth designs.
   • OEM fitment ensures zero tolerance gaps, critical for Peugeot/Citroen transmissions.

2. Version Selection Guidance:

   • Base Model: Ideal for routine maintenance on BX or 305 models with moderate driving conditions.
   • Advanced Model: Suitable for professional mechanics working on high-mileage Xantia or ZX vehicles.
   • Pro Model: Required for heavy-duty applications (e.g., towing) in Professional or TT models. Its 220°C heat resistance enables safe operation in extreme environments.

With the Pro Model’s aerospace alloy, you can eliminate transmission slippage even during prolonged high-load driving. Pair it with the diamond-tooth design to ensure 99.8% clutch engagement accuracy—critical for Citroen Professional engines.
