The Rampage Frameless Trail Top installs over the original equipment factory roll bar for a snug fit. This unique design allows for larger side windows and improved visibility with removable side and rear windows that quickly convert the soft top into an open Safari top. Windows use heavy duty molded tooth zippers and are easily replaced or removed. The windows are also stored in a special separation panel between the ceiling and roof top which is concealed to protect the windows from scratches or puncture. The fastback style offers improved aerodynamics and a quieter ride than factory bow style tops. The windshield channel, door surrounds and tail gate bar are required. These can be purchased separately.
