Front wiper blades
The RX 350’s front windshield wipers come in two sizes: one for the driver’s side and one for the passenger’s side. The driver’s blade is longer to sweep more of the windshield, while the passenger blade fills the opposite side.
- Driver’s side: 24 inches
- Passenger’s side: 18 inches
These dimensions cover the standard US-spec RX 350 from model year 2011. Some markets or trim levels may use slightly different lengths, so always confirm before purchasing if your vehicle is outside the primary market.
How to verify sizes for your vehicle
Check the owner’s manual, the driver-side door jamb label, or use an online “fit finder” from a reputable wiper brand by entering your vehicle’s year, make, model, and trim. If replacing blades yourself, you can also remove the current blades and measure their length to ensure you buy correct replacements.
Rear wiper blade
The RX 350 also has a rear window wiper blade in addition to the front blades. The standard rear blade size for most markets is:
- Rear: 12 inches
As with the front blades, rear wiper size can vary by market. If you observe unusual blade fitment, double-check the part number or consult your local dealer or parts retailer to confirm compatibility for your specific vehicle configuration.
Replacement tips
When swapping blades, ensure you choose the correct connector type and installer method. Some blades use pin-type connectors, others use hook fittings. For best performance, replace both front blades at the same time and inspect the rear blade for wear, especially if you’ve had to clear snow or ice.
Summary
For the 2011 Lexus RX 350, the standard front wiper setup is 24 inches on the driver’s side and 18 inches on the passenger side, with a 12-inch rear blade. Always confirm with your vehicle’s VIN or owner’s manual in case your market or trim differs, and consider replacing all blades together for even performance.
