The GL450 spans two body generations — the X164 (2007-2012) and the X166 (2013-2016) — and they don’t share wiper blade lengths, so “GL450 wiper blades” isn’t a single answer until you know your generation. The X166’s common fitment is a 26″ driver-side and 22″ passenger-side front pair plus a 12″ rear blade; confirm your exact model year before ordering any of the sizes below. All nine picks here are sold in (or can be ordered in) that 26″/22″ front sizing.

The picks, in detail
Bosch ICON
Bosch’s flagship beam blade, sold as individual 26″ and 22″ blades to match the GL450’s front pair.
- Dual-point steel bridge distributes pressure evenly across the blade
- Up to 40% longer blade life claimed vs. conventional blades
- Weather-shield double-locking connector
- Widely available at auto parts chains for quick replacement
- Beam design sheds ice and snow well
- Sold as single blades — you need both the 26″ and 22″ for the front pair
- Premium price per blade compared to Rain-X or Denso
Rain-X Latitude
A 2-in-1 beam blade with an integrated spoiler and a graphite coating, sold at a lower price than the premium beam brands.
- 2-in-1 beam design integrates the spoiler into the blade
- Graphite-coated rubber for a smoother wipe and water repellency
- Universal adapter fits factory J-hook arms
- Lower cost per blade than Bosch or PIAA
- Good all-around wet-weather performance
- Shorter service life reported than premium beam blades in some owner reviews
- The universal adapter fits most vehicles, so double-check GL450 arm compatibility before buying
PIAA Si-Tech Silicone
A silicone-edge blade in the exact 26″/22″ sizes the GL450 needs, trading a higher price for longer UV/heat life.
- Silicone rubber wiping edge instead of standard rubber
- Silicone-coats the windshield over time, reducing future streaking
- Available in the exact 26″/22″ sizes the GL450 needs
- Silicone lasts significantly longer than rubber in UV and heat exposure
- Smoother, quieter wipe once broken in
- Priced higher per blade than most rubber-edge competitors
- Silicone blades can squeak until they’re broken in
Michelin Stealth Ultra
A hybrid beam/hard-cover design from Michelin, sold as single blades in GL450-matching sizes.
- Hybrid beam design with a hard protective cover
- “Smart Technology” aerodynamic spoiler for high-speed stability
- Sold as single blades in the exact GL450 sizes
- Well-regarded mid-price beam option
- Hard cover protects the beam spring from ice buildup
- Pricing varies widely by retailer — shop around
- Not a silicone edge, so lifespan trails PIAA in high-UV climates
Michelin Pro Plus Silicone Twin Pack
Michelin’s silicone-edge blade sold as a matched front-pair twin pack, removing the guesswork of buying two single blades.
- Silicone wiping edge in a matched front-pair twin pack
- Sized for GL450-matching front pairs (26″/22″ and similar)
- All-season silicone formulation
- Twin-pack sizing removes the guesswork of buying two single blades separately
- Silicone longevity similar to PIAA
- Twin-pack pricing is one of the higher totals on this list
- Availability varies by exact size pairing — confirm 26″/22″ is in stock
ANCO 31-Series
A budget-friendly, traditional hooked-arm-compatible blade widely stocked at auto parts stores for same-day replacement.
- Traditional hooked-arm compatible blade
- Multiple pressure points along a contoured spring
- Widely stocked at auto parts stores
- Budget-friendly without dropping to bargain-bin quality
- Easy same-day replacement availability

Valeo 900 Series Ultimate
A frameless beam blade from Valeo, a supplier to several European automakers, at a mid-range price.

- Beam and hybrid designs depending on the specific part number
- Broad size range covering GL450 fitments
- Lowest-cost entries on this list for budget-minded owners
- OE-supplier pedigree
- Price and design vary a lot across Denso’s own lineup — confirm you’re getting a beam style, not a bargain conventional blade

Genuine Mercedes-Benz OEM Wiper Blade Set
The factory-matched front pair (and rear blade), sourced through Mercedes dealers or OE-parts specialists for guaranteed fit.
- Factory-matched front pair engineered for the GL-Class
- OE part number sourced through Mercedes dealers or OE-parts retailers like FCP Euro
- Guaranteed fit with no aftermarket-adapter guesswork
- Zero fitment risk — it’s the factory part
- Available through OE-parts specialists at less than full dealer markup
- Most expensive option on this list at full dealer pricing
- No performance upgrade over aftermarket beam blades — you’re paying for guaranteed fit, not extra capability
Buying tips
- The GL450’s rear wiper (12″ on the X166) is easy to forget — most searches and kits default to the front pair only.
- X164 (2007-2012) and X166 (2013-2016) generations use different blade lengths — check your specific model year, not just “GL450.”
- Beam-style blades (Bosch ICON, Michelin Stealth Ultra) shed snow and ice buildup better than traditional hooked-arm blades if you’re in a winter climate.
