S77-1039-2901 | Genuine Kenworth® B-Panel Reinforcement Dash Panel

• Provide structural support

  • Prevents flexing or movement of the dashboard.

  • Ensures the dash remains rigid—especially around mounted electronics or gauges.

• Enhance safety

  • Helps maintain the integrity of the dash in the event of a crash.

  • May contribute to energy absorption or keeping components from shifting into the cab.

• Support mounted components

  • Holds or stabilizes heavier dash items like instrument clusters, HVAC controls, infotainment systems, or switch panels.

• Prevent squeaks and rattles

  • Reduces vibration and noise by keeping the dash stable.

The dash feels loose, bouncy, or shaky when touched.

You may notice it flexes when pressing buttons, controls, or resting hands on it.

May be more noticeable on rough roads or when hitting bumps.

2. Squeaks, Rattles, or Vibrations

Unusual noise from behind the dash, especially near the center console or passenger side (where B-panel reinforcements typically sit).

Sounds worsen over time or with vibration from the engine or road.

May sound like metal-on-metal or plastic creaking.

3. Misaligned or Loose Dash Components

Switch panels, HVAC vents, or gauge clusters appear misaligned, uneven, or popping out.

Some components may droop or shift when the truck is in motion.

Mounting screws may keep coming loose or not hold properly.

4. Electrical or Control Module Problems

Wiring harnesses and modules mounted to the reinforcement may get stressed or pulled.

Could result in intermittent electrical issues, failed switches, or loose connectors.

Controls on that part of the dash may not respond correctly.

5. Visible Cracks or Breakage (on disassembly)

If you open or remove the dash panel, a failing reinforcement might be:

Cracked

Bent

Rusting (if metal)
