BMW Timing Chain Tensioner | Fits N52, N54, N55 & S55 Engines | OEM Part No. 11317584723

Stop Chain Rattle Before It Becomes a Costly Repair

The BMW timing chain tensioner (OEM part no. 11317584723) is a vital component that keeps your engine’s timing chain tight and properly pressurized. Over time, the factory tensioner weakens, creating slack in the chain that leads to chain rattle, slapping, and premature wear. Left unchecked, this can escalate into major engine damage requiring a full timing chain and guide replacement.

Why Replace Your Tensioner?

• Prevents Timing Chain Slack: Maintains proper chain tension to avoid slap and misalignment.
• Eliminates Rattle & Noise: Fixes the common BMW “cold start rattle” and chain chatter.
• Protects Engine Longevity: Reduces wear on guides, sprockets, and the chain itself.
• Cost-Effective Preventive Repair: A simple bolt-in replacement that can save thousands versus a full timing chain job.

Protect your BMW from timing chain failure. Replacing your worn tensioner with this OEM-grade unit is the most effective preventive step against rattle, slap, and expensive repairs down the road.
