Product Introduction

• Structure: Made of high-quality EPDM rubber material with integrated extrusion molding, featuring a special U-shaped clamping structure on one side and a matte anti-slip surface on the other. The belt has uniform thickness and pre-designed telescopic joints, adapting to the radian of the fender panel without cracking.

• Performance: EPDM rubber has excellent aging resistance, high and low temperature resistance and oil resistance, able to withstand long-term outdoor exposure and vehicle vibration without hardening or deformation. The good elasticity ensures tight fitting with the fender and vehicle body, and the oil-resistant performance prevents corrosion from road oil stains and hydraulic oil.

Core Function

1. Sealing & Dustproof: Fills the gap between the fender panel and the vehicle body/chassis, effectively blocking road dust, mud and small stones from entering the fender inner cavity and chassis parts.

2. Noise Reduction: The elastic rubber material absorbs the vibration between the fender panel and the vehicle body, and reduces the wind noise generated by air flow passing through the gap during driving.

3. Buffering & Anti-collision: Provides a soft buffering effect between the metal fender bracket and plastic panel, avoiding hard contact and scratch damage caused by vehicle vibration.
