The standard sizes are: front driver side 24 inches, front passenger side 17 inches, and rear blade 12 inches.
Front wiper blades
For the 2008 RX 350, the two front blades are not the same length. Knowing the exact lengths helps ensure a proper fit and full windshield coverage when you shop for replacements.
- Driver's side: 24 inches
- Passenger's side: 17 inches
When replacing, you can choose either traditional frame blades or modern beam-style blades, but match the lengths above for optimal performance. Replacing blades in pairs is often recommended to maintain even wiping across the windshield.
Rear wiper blade
The rear window on the 2008 RX 350 uses a single blade. Confirming the correct length before purchase helps avoid returns and ensures clear rear visibility.
- Rear blade: 12 inches
If your hatch has any unusual trim or a different rear wiper setup, check the packaging or your owner’s manual to verify the exact rear blade length before buying.
Verification and quick tips
Always double-check by measuring the current blades or consulting the vehicle’s manual. Retail listings often show compatibility by year, make, and model, which can help prevent ordering the wrong size. If you’re replacing both front blades, consider installing the same model on both sides for consistent contact and performance.
Summary
For the 2008 Lexus RX 350, use 24-inch driver-side front blades and 17-inch passenger-side front blades, plus a 12-inch rear blade. Confirm fit with your specific vehicle or packaging, and consider replacing both front blades at once for even wiping performance.
