Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Precision Engine Synchronization: The timing chain kit ensures accurate coordination between camshafts and crankshaft, maintaining optimal engine timing for BMW N63, S63, and compatible 4.4T engines.
  • Component Integration: Includes critical parts like the metal timing chain, tensioners, guides, and VVT gears to reduce wear, prevent slippage, and enhance durability under high-performance conditions.

Key features

  • 1. Corrosion-Resistant Steel Construction

    • With a corrosion-resistant steel timing chain and metal components, ensure long-lasting durability in high-stress engine environments. Outperforming plastic-based alternatives in wear resistance*, this design maintains structural integrity even under extreme temperatures and mechanical stress.

  • 2. Precision Engine Synchronization

    • With precise gear-to-chain meshing and VVT (Variable Valve Timing) compatibility, achieve optimal timing for high-revving 4.4T BMW engines. Delivering up to 15% improved timing accuracy over generic timing kits*, ensuring smooth valve and piston coordination.

  • 3. OE-Certified BMW Fitment

    • OE-certified fitment (11367540348, 11317605195) guarantees seamless integration with BMW N63/S63 engines. Reducing installation errors common with non-OE kits*, this kit is pre-tuned for models like the M6, X5 M, and Alpina B7.

  • 4. Self-Adjusting Tensioning System

    • With spring-loaded tensioners and guides, maintain consistent chain tension even during prolonged high-RPM operation. Outperforming fixed designs in minimizing slack and noise*, extending component lifespan.

  • 5. Comprehensive OEM Certification Standards

    • Certified to BMW’s OE specifications, this kit meets rigorous engineering and durability benchmarks. Exceeding the reliability of uncertified aftermarket alternatives*, it includes all required components (chain, tensioners, guides, sprockets) for a complete replacement.
