The Jeep Rocklander Roof Trusses are for use with Wrangler 2-Door JL . The roof Trusses integrate with the front and rear hoops to create a rigid and stable cargo management system. This system will allow you to carry significantly more cargo, and provide space for accessories like Grab Handles, Accessory Mounts, Light Bar Mounts and more! Utilizing a matrix of 3/16" steel pier-plates, base anchor footings, and 2" diameter steel columns, it interconnects a framework that allow for "seismic" forces to be handled readily with its unique mechanical advantages. The front hoop without the need for additional support; this strength is the bedrock that allows it to withstand fore and aft thrust, side load forces, and prevents horizontal racking (the twisting/flexing out of a rigid or supportive state). The rear hoop columns are attached with 3/16" steel base anchors and flexural footings. The flexural footings coupled to 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. Roof trusses are made from strong 2” OD steel tube and are attached with CNC billet clamps to the fore and aft hoop columns. The roof trusses have been engineered with forward slopes to reduce outward forces on the front body mounted hoop columns; the rear facing billet clamps attach directly to the frame mounted rear hoop columns, where any thrust forces are dealt with utilizing base anchored/flexural footings. The roof trusses are positioned low, as bowing is not an issue with the colossal strength, ensuring the lowest center of gravity possible when at capacity. The JL ARS Rack will support up to 350lbs of dynamic weight and over 850lbs quasi static loads. *Please select the correct bumper configuration for your Jeep Product Features Heavy Duty 2" Tubular Exo-Skeleton Rack System 850lbs (Static) & 350lbs (Dynamic) Load Capacity Three Piece Front Hoop Design Front Hoop Weld on Grab Handles Front Steel Pier Plates Integrated Fastener System Rear Steel Flexural Footings Two Piece NVH Hi-Durometer Urethane Bushings 3/16" Steel Base Anchors 2-Door Roof Trusses CNC Clamps with Threaded Bolt Holes Specific Engineered Tube Bend for a Stronger Front Support Structure Industrial Grade Corrosion Resistant Hardware Protection for Windshield Assembly Protection for the Rear Corners Low Profile Design Finished in Black Texture Powdercoat Included in Kit Front Hoop Pier Plates Roof Trusses Rear Hoop Frame Mount Brackets Flexural Footings NVH Urethane Bushings All Required Hardware
