Western Star wiper FAQ
Answers worked out from our Western Star data.
What size wiper blades does my Western Star need?
It depends on the model and year. On Western Star models from 2014 on, front blades run from 20" to 20", and the most common pair (driver + passenger) is 20" + 20", on 9 of 9 models. Older models differ; pick yours above for the exact sizes by year.
Do all Western Star models use the same wiper arm?
Not all. On their newest years we have confirmed the arm on 9 of 9 recent Western Star models, most often J-Hook (9×3 mm). For the other 0 we haven’t confirmed it yet, so check where the blade clips onto your arm before buying.
Does WiperFinder list rear wiper sizes for Western Star?
Not yet. Our data doesn’t have a rear blade size for any Western Star model. If your car has a rear wiper, measure the old blade before you buy.
Why do some Western Star years show no sizes?
Our data runs to 2020 and doesn’t cover every model year yet; some years list only some of the blades. We mark those years on each model page instead of guessing.
