Bought these radiators and installed them on my bike. Found that lower crossover radiator hose to tough exhaust manifold. After looking into it further found that mounting brackets are bent opposite of what factory radiator brackets bent. this push radiators away from the frame of the bike making crossover hose to short. when stretching hose to get hose on the radiator barbs it take the bend out so the hose lays on exhaust manifold. It took 2 week of fight with these people to get my money back these radiator do not fit a 2013 rmz 450 correctly do not buy this product.
