A bent arm, a weak spring or snow damage can leave streaks or let the blade lift off the glass. A worn blade, the wiper motor or loose linkage can be behind those signs too, so find the cause before buying an arm.

Fits

This front left windshield wiper arm also fits the 2017-2024 Ram 2500 and the 2019-2024 Ram 1500 Classic. These vehicles take one arm on each side of the windshield. This listing is one arm for the front left; the front right is a separate part, and the two are normally replaced together.
