Trico B98999-146 Wiper Arm Adapter Kit

Trico Wiper Adaptor for Heavy Duty Applications

The Trico B98999-146 wiper arm adapter kit is a metal, screw-on adapter built for heavy duty windshield wiper setups. It is specified for Fleetwood, National RV, Hino, Mitsubishi Fuso, and UD Truck models that use heavy duty blades and a 2-screw bayonet blade design.

As part of Trico’s Wiper Adaptor line, this adapter supports vehicle-specific windshield wiper connections where a secure metal interface is needed for demanding commercial and RV service. The black finish and universal fit design make it a practical replacement for heavy duty truck and medium duty truck wiper systems.

Product Details

This wiper arm adapter kit is engineered for windshield wiper service on medium duty truck and heavy duty truck platforms. The adapter measures 2.1555 in length and uses a metal body with a black blade finish for a durable connection point between the wiper arm and blade assembly. Trico B98999-146 is the correct style of adapter when the vehicle calls for a screw-on, 2-screw bayonet interface rather than a standard passenger-car connection.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Loose or incorrect wiper blade attachment on heavy duty vehicles
• Wiper blade fitment issues on 2-screw bayonet systems
• Replacement needs for worn or damaged adapter hardware
• Windshield wiping problems on Fleetwood, National RV, Hino, Mitsubishi Fuso, and UD Truck applications
• Service needs for medium duty truck and heavy duty truck wiper assemblies

Installation Notes and Tips

Confirm the existing wiper arm and blade connection style before ordering. This adapter is for screw-on, 2-screw bayonet applications and should be matched to the vehicle’s original wiper interface. For best results, compare the old adapter to Trico B98999-146 and verify the blade style used on your Fleetwood, National RV, Hino, Mitsubishi Fuso, or UD Truck model.

Quality Assurance

Trico is a recognized name in windshield wiper components, and this adapter is built for heavy duty service requirements. Use it where the vehicle specification calls for a metal adapter in the Wiper Adaptor product line.
