Engineered for extreme conditions, the WG1642740010_1 Wiper Arm Assembly delivers uncompromised visibility and durability. As a genuine-grade replacement, this component is part of our premium Howo/Sitrak truck parts portfolio, designed to withstand the toughest on- and off-road environments. With precision-engineered joints and corrosion-resistant coating, this wiper arm ensures consistent pressure and smear-free wiping, keeping your windshield clear in rain, snow, or dust.
The WG1642740010_1 wiper arm assembly is not just another replacement part; it is a precision tool that guarantees safety and reliability. Built from high-grade steel with a multi-layer zinc-nickel coating, it resists rust, pitting, and fatigue even after millions of wipe cycles. The integrated spring mechanism maintains optimal blade pressure across the entire sweep, preventing streaks and chatter. Whether you operate a Howo T7H, Sitrak C7H, or any heavy-duty truck, this assembly fits seamlessly and restores factory-fresh wiping performance.
When you invest in the WG1642740010_1 wiper arm, you are choosing a component that meets the strictest OE tolerances. Many aftermarket arms use inferior springs or thin-gauge metal, leading to premature wear and poor contact. Our assembly undergoes 100% torque and angle testing, ensuring that every unit delivers consistent pressure. Additionally, the pivot joint is pre-lubricated with high-temperature grease, reducing friction and extending service life up to 30% compared to standard alternatives.
Fleet owners and owner-operators alike appreciate the peace of mind that comes with reliable wiper performance. Poor visibility is one of the leading causes of roadside incidents; with this wiper arm, you maintain a crystal-clear view even in blinding downpours. The arm’s aerodynamic design reduces lift at highway speeds, so the blade stays firmly planted against the glass.
Optimized spring geometry delivers 20% more uniform pressure across the blade, reducing wear and eliminating judder. The WG1642740010_1 arm ensures that your wiper blade lasts longer and cleans better.
No special tools required. The splined taper fits perfectly onto the wiper motor shaft, and the retaining clip snaps securely. Pre-adjusted spring tension means you just mount, tighten, and test.

For best results, install the wiper arm with the blade at the lowest point of the windshield. Use a torque wrench to tighten the retaining nut to 18–22 N·m. Periodically inspect the spring for any debris and clean the pivot area with a dry cloth. If you notice any reduction in wipe quality, check that the arm is not bent and that the blade rubber is still flexible. The WG1642740010_1 is designed for minimal maintenance, but regular inspection prolongs the life of both arm and blade.
