LEILI Wiper Arm
SINCE 1989
The wiper arm is a robust mechanical component that connects the wiper motor to the wiper blade, transmitting power to drive the blade in a back-and-forth motion to ensure thorough, streak-free contact across the windshield. LEILI Wiper Arms are fully manufactured in compliance with ISO 9001 and IATF 16949 quality management systems and standards. Every unit delivers OE-grade performance in terms of fit, form and function.
Our Service to Customers

Materials
Made of premium steel/aluminum alloy base materials with electrophoretic or spray-coated anti-rust surface treatment, it boasts excellent weather resistance. It can withstand harsh working conditions such as high temperature, high humidity and salt spray, significantly extending service life and reducing the later maintenance costs of commercial vehicles.

Structure
The swing angle of the arm lever and torque transmission parameters are strictly calibrated to ensure efficient power transmission to the wiper blade. The wiping process is smooth without jitter or stuck, achieving dead-angle-free adhesion across the entire windshield and ensuring clear driving vision in rainy and snowy weather.

OE-grade
Manufactured in accordance with original equipment matching standards, the hole positions, lengths and connection interfaces are perfectly compatible with mainstream commercial vehicle models. No additional modification is required for installation, featuring strong adaptability to meet the mass matching needs of vehicle manufacturers and replacement demands of the aftermarket.

Quality
The entire production process complies with ISO 9001 and IATF 16949 quality management system requirements. Each batch of products undergoes fatigue testing and strength testing, delivering stable and reliable performance that meets OE-grade quality standards.
