4 Door Rocklander Sky Top Rack System for Jeep Wrangler JL | Heavy Duty Roof Rack | Adventure Gear for Off-Roading & Camping

Our rack systems are built on a unique floating foundation that separates and distributes weight to the body and to the frame maximizing structure and support. Utilizing a matrix of 3/16" steel pier-plates, base anchor footings, and 2" diameter steel columns, our system interconnects a framework that allow for "seismic" forces to be handled readily with its unique mechanical advantages.

ARS is the only rack that features a "load bearing" front hoop without the need for additional support; this strength is the bedrock that allows our rack systems to withstand fore and aft thrust, side load forces, and prevents horizontal racking (the twisting/flexing out of a rigid or supportive state). The front hoop columns are attached with 3/16" steel pier-plates that connect to 16 strong mounting points along with 2 additional fasteners at the front assembly of the Jeep body, then the pier plates are discretely covered with the factory cowl for a clean OE look.

The rear hoop columns are attached with our 3/16" steel base anchors and flexural footings, that create an understructure connecting the frame of the Jeep to the hoop for the strongest attachment point. The flexural footings coupled to our 2” OD steel support columns through 2-part urethane bushings, providing flexural rigidity between the frame and body mounts that allow the front and rear foundations to work in unison to support the cargo structure. The trusses are equipped with CNC steel billet clamps that are secured to the front and rear hoop mounts with corrosion resistant hardware.
