The restrained aesthetics of the Jeep Grand Cherokee WK2 crossover will not hurt to add bright details, and at the same time improve aerodynamics. The Renegade Design team has created exclusive spoilers for this car brand. The roof spoiler gives both exclusivity to the vehicle and increases downforce. Made from quality composite materials and securely in place, the Jeep GC WK2 roof spoiler will last for a very long time.
