Driving a truck already has its stress, no need to add more because of poor visibility. A truck has a large frontal area which displaces a lot of air while moving. Displacing air means increased air pressure and air velocity. If the truck is rolling against a strong wind, this adds to the problem. All these factors cause the wiper to lift or flutter off the windshield resulting in a bad cleaning job, a reduced visibility, increased eye strain and frustration. Auto accessories to prevent wiper lift were developed as early as 1957 but none can compare to Sure Wipe pressure springs. Our wiper springs not only prevent lift but add 30% more pressure to obtain unequaled truck wiper performance.
