2025 Kenworth T680 — Wiper Blade Sizes

Quick reference

Note: Most 2025 T680 tractors use 24 in beam blades on a wide 12 mm J-hook arm. A small number of fleets may spec alternative arms (9x4 J-hook or saddle-style). Always confirm by visual check or with your VIN at a Kenworth dealer. OEM part numbers vary by arm/blade package—consult your parts counter; do not substitute by guesswork.

Best aftermarket replacements

These popular beam/hybrid blades offer strong performance and broad adapter support. Choose 24 in for both driver and passenger.

• Bosch ICON (premium, ~$25–35 each): Excellent all‑weather wipe and durability. Fits standard 9x3/9x4 hooks out of the box; trucks with a 12 mm “wide hook” may require the included HD adapter or a heavy‑duty ICON/HD blade variant.
• Rain-X Latitude Water Repellency (upper midrange, ~$20–30): Beam blade that lays down a hydrophobic coating. Works with common hooks; verify adapter for 12 mm wide hook.
• Trico Force (midrange, ~$20–30): Aerodynamic beam blade with strong winter performance. Check packaging for heavy‑duty/wide‑hook adapter.
• Michelin Stealth Ultra (value-mid, ~$18–26): Durable hybrid frame for stable contact. Ensure compatibility with your hook style.
• PIAA Si-Tech Silicone (premium, ~$28–40): Silicone rubber resists UV and cold; long service life. Confirm adapter fitment for wide hook.

If your T680 uses a true heavy‑duty wide hook or saddle arm, look for HD-specific blades/adapters from the same brands (e.g., Trico HD, Bosch Heavy Duty, ANCO HD) to guarantee a secure connection.

Attachment style

• Most common: J-hook, wide 12 mm (1/2 in). Visually, the hook is broader/taller than passenger-car 9x3 or 9x4 hooks.
• Possible alternatives on some builds: 9x4 J-hook or a saddle/bayonet-style arm. If the supplied adapters in a consumer blade don’t match, select a heavy‑duty blade kit designed for commercial trucks.

Tip: Measure the inside width of the hook and compare to the adapter chart on the blade box. A 12 mm (≈1/2 in) measurement indicates a wide HD J-hook.

How to install

1. Park wipers and switch ignition off. Lift one wiper arm carefully off the glass.
2. On a J-hook: Press the release tab on the old blade, slide the blade down toward the hook opening, then off the arm.
3. Prep the new blade. Select the adapter that matches your hook (wide 12 mm vs. 9x3/9x4). Pre‑attach it if required.
4. Slide the hook through the blade’s opening and pull upward until it clicks/locks. Tug gently to confirm it’s secure.
5. Lower the arm gently to avoid snapping the glass. Repeat for the other side.
6. Test with washer fluid. If there’s play or the blade won’t lock, you likely have the wrong adapter—do not operate until corrected.

Side pin/bayonet/saddle variants: Follow the adapter’s specific instructions (insert pin, tighten saddle clamp, or engage bayonet latch) and verify lock-up.

When to replace

• Interval: Every 6–12 months for highway tractors, or sooner with high mileage, winter salt, or desert UV.
• Symptoms: Streaking, chattering, skipping, noisy passes, split/cracked rubber, or bent frames. Replace in pairs to keep wipe patterns even.
