Purpose and technical function

The rear wiper arm for BMW E81, E87, and E84 series models is responsible for transferring motion from the drive mechanism to the wiper blade, while maintaining the correct operating angle and pressure force. The precisely selected length and profile of the arm enable effective removal of water and debris from the rear window, which improves visibility when driving in rain or snow. Its location on the rear of the vehicle requires resistance to dirt and changing weather conditions, which is why the construction is optimized for durability and stable operation.

Construction and fitment for BMW

The offered wiper arm has been designed specifically for selected BMW models, ensuring it maintains the correct position relative to the glass and the tailgate. The properly shaped working part of the arm works with the dedicated wiper blade, minimizing the risk of skipping, noise, or uneven water clearing. Factory fitment to the BMW body limits the need for additional adjustments during installation and helps maintain the aesthetic appearance of the rear of the vehicle.

Benefits of using an original arm

Using an original rear wiper arm in a BMW translates into a number of practical advantages:

• maintaining the correct wiper operating area on the rear window,
• stable cooperation with the drive mechanism and wiper blade,
• reduction of vibrations and unwanted noises during operation,
• consistent appearance with other body and window equipment elements.

Thanks to this, restoring the efficiency of the rear wiper is possible without compromising on ergonomics and driving safety in difficult weather conditions.

Characteristics of the used component

The wiper arm comes from the secondary market, which allows for reduced repair costs while maintaining the original manufacturer's specifications. The used OEM component is particularly attractive for older generations of BMW, where both part availability and compliance with factory design solutions are important. This type of element is suitable as a replacement in case of mechanical damage, corrosion, or excessive wear of the existing arm.

Support with selection and additional information

Before purchasing, it is worth verifying the compatibility of the arm with the specific body version and vehicle year using the manufacturer's technical data or part numbers in the specification. Proper fitment guarantees trouble-free installation and correct cooperation with the existing rear wiper mechanism.
