The Whiteline rear upper control arm assembly for Mazda Mazdaspeed3 (2004–2013) is a direct replacement pre‑installed with Whiteline bushings to simplify fitment and avoid bushing removal. Coated metal components and resistant synthetic elastomer inserts withstand corrosion, oil and ozone exposure while internal grease reservoirs provide ongoing lubrication. The assembly helps restore alignment, handling precision and braking stability.
