Detailed Description

This Stabilus gas spring is engineered to match the dimensions and attachment style used on select BMW rear liftgate and trunk applications. The 5B-9105EP measures 364.5 mm extended and 220 mm compressed, with 8 mm rod diameter and 18 mm tube diameter, making it a direct-spec replacement for vehicles that require this exact length and force profile. It cross-references URO 51248110327 for the same application.

Compatible fitment includes 1989-1995 BMW 525i, 1994-1995 BMW 530i, 1975-1978 BMW 530i, 1994-1995 BMW 540i, 1993 BMW 525iT, 1985-1993 BMW 535i, and 1991-1993 BMW M5. Fitment notes specify models without spoiler.

What It Helps Address

• Weak or failing trunk or hatch support
• Slow or uneven liftgate opening
• Hatch or trunk lid that will not stay open
• Loss of controlled closing action
• Noise or binding from worn gas struts

Installation Notes and Tips

Verify the existing strut length, force rating, and end fittings before installation. This part uses metal blade connections with retaining clips at both ends, so confirm the attachment style matches the vehicle mounting points. For BMW 525i, 530i, 535i, 540i, and M5 applications, confirm the vehicle is equipped without a spoiler as noted in the fitment data. Replace gas springs in matched condition when the opposite side shows similar wear.
