Engineered for your Western Star 4900 (1985 - 2002), this 18" passenger side beam wiper blade delivers factory-grade windshield coverage and whisper-quiet operation.

An integrated wind spoiler keeps the blade pressed firmly against the glass at any speed, while the multi-point pressure system ensures uniform contact from tip to tip — no streaks, no skipping, no chatter. Fits your Western Star 4900's passenger side wiper arm exactly. Installs in under 2 minutes with our tool-free quick-connect adapter. Protected by our Perfect Fit Guarantee and 12-month warranty.
