All of Big Al’s windshield wipers are made from billet aluminum with a brushed finish. There are three different style arms to choose from (see photo above) with a variety of arm length options. All of our wipers are designed to fit either a 1/4” shaft, a #10-32 threaded shaft, a 1/2” shaft, or a 5/8” shaft. The angle of the blade on our wipers is adjustable to suit many applications. All arm length measurements given are from the center of the shaft to the center of the blade.

Please see the part numbers and descriptions listed on our website to choose the wiper arm, shaft, and blade size appropriate for your application. The multi-adjustable arm was designed to have the option of cutting down the wiper extension (shown in main photo) so that you may get the exact arm length needed for your application. This arm has a maximum extension of Approximately 10 3/4” and may be cut down from there.

The Original style arms and the Smooth Contour arms are all machined to a fixed length and the arm length is not adjustable.
