MetalCloak Rocklander Rack System for 18-24+ Jeep Wrangler JL Unlimited R74000

MetalCloak R74000

The 4-Door Rocklander Rack System is the most capable carrying system available for the Jeep JL Wrangler Unlimited. The highest payload, strength, rigidity, and stability as well as an assortment of unique modifications are feature characteristics of this cargo management system.

ARS has created a structure to safely handle additional cargo loads for your Jeep. 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.

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 our 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.
