Replacement RB61030010 Trunk Lid Tension Spring Left Side without Auto Pull-Down

The Replacement RB61030010 is a left-side trunk lid tension return spring designed as a direct-fit OEM replacement for 2011–2016 BMW 5 Series (F10/F10N) sedans not equipped with the auto pull-down feature. This spring works in tandem with the trunk lid assembly to provide smooth, consistent assist when opening and closing the trunk lid, restoring the factory feel and function lost when the original spring wears out or breaks.

Engineered to match OEM specifications, this replacement spring installs without modification using the existing mounting points. It directly replaces BMW OEM part number 51247204366 (left/short side). Note: the right-side spring (51247204367) is sold separately.

Key Features:

• Direct replacement for BMW OEM part number 51247204366
• Left-side (driver side / shorter) trunk lid tension return spring
• Designed for vehicles without the factory auto pull-down trunk feature
• Made from durable steel construction for long service life
• Direct-fit design — no modifications required for installation
• Restores proper trunk lid operation and OEM-quality feel

This spring is sold individually. For a complete restoration of trunk lid operation, it is recommended to replace both the left (51247204366) and right (51247204367) springs at the same time.
