Accessory Belt Service Kit - N55

Product Details

When you push your BMW to its limits your accessory drive system is working overtime. A worn belt tensioner or a noisy idler pulley can lead to thrown belts, loss of power steering mid corner, or an overheated engine

This comprehensive drive service kit is built around high grade Continental and INA original equipment parts. Designed to handle high load operation, this kit restores factory belt geometry and dynamic tensioning to ensure your alternator, water pump, and power steering stay fully engaged when you need them.

What's Included:

• Continental Accessory Drive Belt – Multi-ribbed EPDM belt built to resist high heat, cracking, and slip at elevated engine speeds.

• INA Belt Tensioner Assembly – Heavy-duty internal spring assembly that dampens harsh load spikes and prevents belt whip under hard acceleration.

• INA Idler Pulley – OEM sealed-bearing deflection pulley for smooth, high-RPM stability.

• INA Secondary Idler Pulley – Precision-aligned guide pulley designed to withstand thermal expansion and high radial loads.

Performance Highlights:

• Engineered to maintain consistent tension under aggressive gear changes and high RPMs.

• Direct replacement with no modifications required, preserving factory clearance and alignment.

• Restores maximum accessory drive efficiency and cures high-RPM belt slip or start-up squeal.
