The K9 Roof Rack System from Eezi-Awn is a revolutionary advancement in expedition-style racks. It is thinner, lighter, stronger, quieter, more functional, more aerodynamic, more durable, and more aesthetically complimentary to your vehicle than the competition.
The K9 systems for the 5th Gen 4Runner come in 1250mm (49") width, and 5 different lengths. Far and away the most popular model is the 2.2M (87") long rack that starts a few inches behind the windshield and finishes an inch in front of the rear hatch. This rack maximizes your roof top capacity. The 1.6M (62") version is a great choice if you want to maintain the use of your sunroof. It starts just behind the sunroof and finishes an inch in front of the rear hatch.
Capacity of the K9 roof rack system is broken into two measurements, static weight and dynamic weight. Static is when the vehicle is stationary. Dynamic is when the vehicle is in motion. The K9 racks have not been tested on vehicles to the point of roof failure. Eezi-Awn has not tested the K9 racks on vehicles to the point of roof failure. Eezi-Awn can tell you what they've tested themselves effectively. A dynamic capacity in the range of 500 pounds is possible. That load included a RTT, awning, dual fuel can holder, aluminum storage case with recovery gear, shovel, axe, under mount table, light bar, etc on a 2.2M long rack. A static capacity of 1000 pounds is possible. An example of static load increase would be adding people in the tent on the roof. Please understand these capacities are on vehicles that have modified suspensions designed to manage this amount of weight. They are not a warrantied or guaranteed capacity. Your load capacity will vary.
