Arconic's advances LvL ONE ® process technology results in a brilliant finish. LvL ONE ® has a smoother and glossier surface than Brushed but requires the usual procedure when it comes to maintenance. If a shiny surface is desired, polishing is needed. Nevertheless the wheel looks great and comes with the same advantages as other finishes of Alcoa Wheels ®. As with all Alcoa wheel products, Alcoa LvL ONE® wheels are forged from one solid block of Aluminium and withstand the most severe tests, one of the reasons why Alcoa grants a Five Year Unlimited Mileage Warranty.
