Product Description:
The factory front lower control arms are an integral part of the B9/B9.5 Audi A4/S4/RS4 and A5/S5/RS5 suspension, but can start wearing out as early as 40,000 miles - especially on enthusiast-owned vehicles which are driven hard on the street or track. As the rubber bushings degrade and ball joints develop play, alignment is compromised and steering becomes less precise.
034Motorsport's complete Density Line Lowers Control Arms are designed to be a performance replacement for all four of the factory front lower control arms. Featuring high-durometer rubber bushings and high-quality ball joints, Density Line Lower Control Arms are engineered to limit unwanted deflection in the suspension, resulting in tighter handling and more precise steering response than even brand new factory control arms can offer.
