057109513B 95510551310 Timing Chain Slide Rail for Audi A4 B8 Q7

Timing Chain Slide Rail for Audi A4 B8/Q7 (057109513B / 95510551310)

1. Part Numbers: This timing chain slide rail features OEM part numbers 057109513B and 95510551310, ensuring precise compatibility with Audi models. These codes validate its authenticity and guarantee a factory-spec fit for optimal engine timing performance.
2. Vehicle Compatibility: Specifically engineered for:
   • Audi A4 B8: 2007–2015
   • Audi Q7 (4L): 2006–2015
     Suits 3.0L TDI (CRCA, CASA), 4.2L FSI (BFM), and 4.2L TDI (CASA) engines. Verify your vehicle’s engine code (e.g., BFM for 4.2L FSI) and production year for exact fitment.
3. Function and Quality: The timing chain slide rail guides the timing chain to maintain proper alignment, reducing wear and preventing slack that can cause engine misfires or damage. Constructed from high-strength composite material with heat-resistant properties (up to 140°C), the rail features a self-lubricating nylon surface and integrated metal reinforcements for durability. Its precision-molded design ensures seamless OEM integration, while the contoured shape optimizes chain tension and minimizes noise. Replace worn slide rails during timing chain service to address common issues like plastic degradation or rail deformation, restoring factory-level timing precision and preventing potential engine damage from chain misalignment.
