The Rampage 109435 Frameless Trail Tops install over the original equipment factory roll bar for a snug fit without the need for additional bows or support hardware. 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 and stored in a special separation panel between the ceiling and roof top which is concealed and protects the windows from scratches or puncture. The fastback style offers improved aerodynamics and a quieter ride than factory bow style tops.
