Product Details

The Bilstein B4 OE Replacement line is focused on maintaining original vehicle behavior rather than changing it. This front strut assembly uses a twintube design and OE-style mounting points to support controlled damping, stable steering response, and the factory ride character on the BMW X5 and BMW X6. If you are replacing a worn front strut on a 2014-2018 BMW X5 or a 2015-2019 BMW X6 with standard suspension, 22-240316 is built for that application.

This part cross-references BMW OE numbers 31 31 6 851 745 and 31 31 6 851 747 for the same application.

Common Issues Addressed

  • Excessive front-end bounce over bumps
  • Reduced steering control or vague road feel
  • Uneven ride quality caused by worn struts
  • Noisy or unstable suspension performance
  • Loss of factory handling balance on standard suspension vehicles
