AEV HighMark Fender Flares are an absolute game changer for Colorado ZR2 and ZR2 Bison owners! Manufactured in the USA out of extremely durable and UV-resistant ABS plastic, these high clearance fender flares open up the front and rear wheel wells substantially, making room for a 35" tall tire with NO LIFT!* This allows you to take full advantage of the Colorado ZR2's extremely capable and incredibly well-engineered OEM suspension system, while also maintaining a lower center of gravity with all the floatation and ground clearance of a larger tire.
