Thanks to the properly selected spring characteristics, the hood opening system maintains factory-standard performance, and access to the engine bay remains convenient and safe.

• preservation of the manufacturer-specified hood opening assistance force,
• consistency with other components in the hinges and locks group, without the need for modifications,
• reduction of the risk of improper closing or excessive load on the hinges.

For the user, this means stable operation of the hood mechanism and no issues with part fitment during installation.

Condition of the component and use in repairs
