Open and hold your BMW's trunk lid with smooth, controlled motion using the Stabilus Trunk Lid Lift Support 5B-732300, a 14.29-inch gas-charged Lift-O-Mat unit. It drops in as a direct-fit replacement for the 2008-2013 BMW 125I, 128I, 135I and SERIES M 125I, plus the 2011 BMW 1 SERIES M — see the Buyer's Guide tab for engine-level fitment.
The Stabilus Lift-O-Mat design uses a longitudinal groove (velocity manifold) pressed into the tube wall so gas flows around the piston with extension speed and damping tuned for this application; the groove 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.
- Internal compression spring: compresses in the closed position to help release the lid from the latch and add a boost during initial opening.
- Corrosion resistance: part coatings tested to automotive standards.
- Based on the OE design: for proper fit, form, and function, and easy to install with no special tools.
For best results, replace in pairs.
