Purpose and Function of the Component

The presented slide bracket has been developed for the rear left part of the body, where it is responsible for proper support and guidance of the bumper. Its placement in the rear area means the element operates in a zone exposed to operational loads, therefore its construction must ensure stability and proper maintenance of the bumper's geometry.

Thanks to its dedicated shape and mounting points, the bracket allows for:

• maintaining the correct line of the rear bumper on the left side,
• reducing stress in the bumper panel during driving,
• preserving proper gaps between body elements.

Benefits of Using an Original Mercedes Solution

The component from the Bumpers and Reinforcements group, designed for Mercedes vehicles, ensures a fit to factory mounting points without the need for modifications. The appropriate geometry of the bracket translates to:

• consistent fitment of the bumper with the side body panels,
• minimized risk of cracking and looseness during driving,
• easier disassembly and reassembly of the bumper during subsequent service work.

Such a fit is particularly important in commercial vehicles, where the rear of the body often operates under variable loads and is exposed to intensive use.

Mounting Characteristics and Application

The left rear bumper slide bracket is designed for installation in a factory-intended location within the body structure. Its task is to maintain the slide in the correct position relative to the bumper and the vehicle's structure, which facilitates:

• precise alignment of the bumper with the tailgate and fenders,
• even distribution of loads on the mountings,
• maintaining bumper stability during daily use.

Its placement in the rear left part of the vehicle allows for targeted replacement of only the element responsible for a specific side of the body, without interfering with other mountings.

Condition and Application in Body Service

The product is offered as a used part, which is a cost-effective solution for post-accident repairs or operational servicing when maintaining functionality and correct bumper installation at a reasonable cost is a priority. This type of bracket is suitable for both local repair of the rear body section and comprehensive restoration of the bumper area on the left side.
