Rear Wiper Blade for Western Star 3800 (1989 - 2001)

Restore clear rear visibility with this 12" premium beam wiper blade, precision-engineered for the Western Star 3800 (1989 - 2001). Our rear blade uses an aerodynamic frameless design that hugs your rear windshield contour for complete, streak-free coverage. The natural rubber wiping element resists UV degradation, cracking, and hardening — delivering consistent all-weather performance through summer heat and winter frost. Spring-loaded tension distributes even pressure across the full blade length, eliminating chatter and missed spots. The integrated spoiler prevents wind lift at highway speeds. Installation takes under 2 minutes with no tools — our universal adapter snaps directly onto your Western Star 3800's rear wiper arm. Backed by our Perfect Fit Guarantee and 12-month warranty.
