• secure lid support – reducing the risk of the lid dropping spontaneously during loading,
• compatibility with factory mounting systems – no need for modifications to brackets or adapters,
• maintaining predictable, repeatable lid movement throughout the full opening range.

A component from this group is particularly important for daily vehicle use – its proper functioning affects the comfort of trunk operation and user safety during loading and unloading.
