IVECO Manual Window Regulator 98407740

The 98407740 is a heavy-duty manual window regulator produced by TinzerMotor for IVECO commercial trucks. While the part number is traditionally associated with a manual mechanism, TinzerMotor’s heavy-duty version is built to provide high-leverage, smooth operation for the front left-hand (driver side) window.

• Rigorous Testing: TinzerMotor subjects every unit to professional-grade validation:

• Stress Testing: The manual handle and gear assembly are tested for high-torque resistance to ensure the mechanism doesn't jam when the window is frozen or dirty.

• Life-Cycle Durability: Verified for over 30,000+ manual cycles, ensuring years of reliable service in harsh environments.

• Fitment Guarantee: Each unit is 100% checked against OEM dimensions to ensure a "perfect bolt-on" installation, minimizing downtime for the truck.
