Genuine Rear Door Check Strap for Ford Ranger Mazda BT-50 2013-2021 UC9M72270D

Genuine rear door check strap for Ford Ranger Mazda BT-50 2013-2021, part no. UC9M72270D is a body and door component designed to limit the opening angle of the rear door and hold it at fixed opening positions. This part helps prevent the door from opening too far, reduces impact from wind or when the vehicle is parked on an incline, and improves safety and convenience for users.

On the 2013-2021 Ford Ranger and Mazda BT-50, the rear door check strap is installed between the vehicle body and the rear door, working in sync with the door hinges to control the opening and closing travel. When the door is opened, the retaining mechanism creates holding positions that keep the door steady at different opening angles, preventing it from swinging shut or opening too forcefully in strong wind while also reducing load on the door hinges.

The genuine check strap is made from high-strength steel with excellent load-bearing capacity and wear resistance. Inside, a precision-machined spring and roller mechanism delivers stable retention force, helping the door operate smoothly and maintain long-term performance. The surface is treated for corrosion resistance, making it suitable for hot, humid climates and harsh operating conditions.

After a period of use, the door check strap may wear at the retaining mechanism, bend, or suffer spring failure, causing the door to lose its holding positions, make noise when opening or closing, or swing shut unexpectedly. If not replaced promptly, the door hinges and related parts will bear greater load, reducing the lifespan of the door system.

Genuine part UC9M72270D is manufactured to Ford and Mazda original standards, ensuring high durability, stable retention force, and accurate fitment on the 2013-2021 Ford Ranger and Mazda BT-50.
