Western Star 4900FA Driver Side Wiper Blade — 20" Perfect Fit

Upgrade your Western Star 4900FA (2002 - 2020) with this premium 20" driver side wiper blade — precision-engineered for a factory-perfect fit on your windshield. Our beam-style flat blade uses a frameless aerodynamic design that hugs every curve of your Western Star 4900FA's glass, delivering uniform pressure from tip to tip for streak-free, chatter-free performance. Built with a natural rubber squeegee edge and a durable steel spring tensioner, this blade handles rain, sleet, and snow with quiet, smooth operation. The integrated wind spoiler keeps the blade pressed firmly at highway speeds, while the UV-resistant housing protects against sun damage and cracking. No adapters required — the universal J-hook connector (plus included adaptors for pin-arm, bayonet, and side-lock mounts) snaps onto your Western Star 4900FA wiper arm in under 2 minutes. No tools needed. Eco-conscious manufacturing: our blades use recyclable packaging and responsibly sourced natural rubber. Backed by our 12-month warranty and perfect-fit guarantee — if it doesn't fit your Western Star 4900FA, we'll refund you in full.
