Mercedes® Premium Roller Bearing Window Regulator, Rear Right With Motor, 1984-1993 (201)

Quality Replacement Part Offsets Dramatic Increases In Window Guide Friction From Dirt Buildup Virtually Eliminates Friction Within The Cable Regulator Itself. The window regulator is just another name for the channel and pulley system that guides the window's path up and down. With time, this system weakens from coagulated grease and dirt build up in the teeth and pulleys of this system causing the power window motor to overheat and fail. Occasionally, the added resistance breaks the critical plastic pieces that keep everything moving smoothly. URO Premium products feature a more robust design and/or higher-grade materials to vastly improve the reliability and durability of the product.
