• Fitment: Fit for N51, N52, N54, N55, S55 3.0L inline six cylinder engine.
• Replacement: Replace for 11317584723 11317532056 11314552380.
• Adopting a hydraulic and mechanical composite structure, with built-in high-pressure damping and strong reset springs, it can automatically compensate for tension in real-time with chain wear, temperature changes, and engine speed fluctuations, always maintaining the optimal tension of the timing chain, and preventing gear jumping, abnormal noise, and valve misalignment. Hydraulic damping design can effectively buffer chain impact, adapt to N52/N53/N54 inline six cylinder high load and high-speed working conditions, and ensure long-term stable operation of the timing system.
• The installation hole position, stroke, and damping characteristics are completely matched, and can be replaced in situ without modification. The main body adopts a high-strength alloy shell, and the key friction surfaces are treated with wear-resistant hardening. The built-in seals are resistant to oil and high temperature, which can resist the high temperature, oil pollution, and vibration environment of the engine compartment, greatly extending the replacement cycle and reducing the frequency and cost of timing system maintenance.
• By optimizing the tension arm and damping parameters, the chain shaking and resonance are effectively suppressed, significantly reducing the operating noise of the timing system and improving the overall NVH performance of the vehicle. A stable tension can prevent the chain from becoming too loose, skipping teeth, and increasing wear due to excessive tension. It protects the camshaft, sprocket, and valve mechanism, ensures precise engine timing, maintains power output and fuel economy, and reduces the risk of engine overhaul caused by timing failures at the root.
