NEW OEM Tesla Model S/X HV Cable Guide Rear Sill Right-Hand 1058279-00-B

The NEW OEM Tesla High Voltage (HV) Cable Guide Rear Sill RH (Part Number: 1058279-00-B) is a Tesla factory-original component designed to route and protect high-voltage cables along the right-hand side rear sill of the Model S and Model X. This guide plays an essential role in securing and organizing HV cabling, reducing stress and wear, and ensuring safe and efficient operation of the vehicle’s battery and electric drivetrain systems. Engineered from high-durability, heat-resistant composite material, this guide is built to endure the thermal and mechanical stresses found in the high-voltage architecture of Tesla’s EV platforms. It keeps cables aligned, prevents contact with sharp edges or moving parts, and helps maintain compliance with Tesla’s strict safety and serviceability standards.
