NEW OEM Tesla Cybertruck Rear Door Check Strap 1801457-99-B

Restore smooth and controlled rear door operation with the NEW OEM Tesla Rear Door Check Strap (Part Number: 1801457-99-B), engineered specifically for Tesla Cybertruck applications. This genuine Tesla door check strap is designed to control the opening and closing movement of the rear door, preventing it from opening beyond its intended travel while providing positive holding positions during normal use. The check strap helps reduce stress on the door hinges and surrounding body structure by absorbing opening forces and maintaining controlled door movement in a variety of conditions. Manufactured from high-strength automotive-grade steel with a precision-engineered pivot and detent mechanism, this OEM assembly is built to withstand thousands of opening and closing cycles while maintaining smooth, reliable performance. Its corrosion-resistant finish protects against moisture, road salt, and environmental exposure for long-lasting durability.
