The plastic gear mechanism is engineered to engage smoothly with the window motor (sold separately), ensuring precise window movement. This regulator is designed for electric window systems and does not include a motor or mounting hardware, so those components must be sourced separately. The bolt-on attachment type allows for a secure fit in the door assembly of compatible vehicles.
