Keep the hood raised and steady with the Stabilus Hood Lift Support 5B-637448, an 11.14-inch gas-charged strut with dynamic damping speed control. It installs as a direct-fit replacement for the 2018-2024 BMW X3 and 2019-2025 BMW X4 (see the Buyer's Guide tab for engine-level details), delivering the smooth, controlled hood motion these vehicles were built around.

This is Stabilus' Lift-O-Mat design, which uses a longitudinal groove (a velocity manifold) pressed into the tube wall so gas flows around the piston with extension speed and damping engineered for this specific application. The groove profile gradually narrows toward the end of the stroke for a gentle, controlled stop.

  • Dynamic damping speed control: creates a fluid opening motion with no bouncing or jerking during cycling.
  • Corrosion-tested coatings: part coatings tested to automotive standards for corrosion resistance.
  • Based on the OE design: engineered for proper fit, form and function.
  • Easy to install: requires no special tools; for best results, replace in pairs.
