4 DOOR SYSTEM POWER UP! AutoLocs flat-glass power window conversion kit allows you to convert your old flat glass windows into a completely new power system. AutoLocs revolutionary Super Glide window design assures easy installation and guaranteed smooth operation. Each kit comes with high-torque worm-gear driven Bosch motors, reinforced guide tracks, and adjustable window bases, all of which assure quick, quiet, and dependable operation for the life of your vehicle. With each kit you get 7 #3 switches and switch frames. With 10 optional cases to choose from you can get just the custom factory look you want. Because of their high-torque motors and custom mounting brackets, AutoLocs Power Windows are great for older cars that have never had power windows. Each PW55037 kit can be upgraded to remote operation using any of AutoLocs keyless entry units or window controllers (PWRE75). Each kit comes with detailed instructions and a Limited LIFETIME WARRANTY.
