Do your windows on your factory JL Soft Top need to be replaced? Bestop now offers factory JL replacement windows - available as individual purchases. Please Note: Side quarter windows do not include the factory corner stiffener when a replacement window is purchased, please make sure to remove the stiffener from the previous side quarter window and reuse it in the new replacement side quarter window. Instructions on how to do this are included with the replacement window purchase. Tinted windows offer an 18% tint for maximum protection to meet US and European regulations.
