NVH is the measurement of how much noise, vibration, & harshness gets transmitted into the cabin of your vehicle. 034Motorsport Control Arms with Density Line Rubber Bushings transfer none to low amounts of NVH to the cabin based on user feedback. NVH is subjective so some users may find NVH to be increased or decreased from our rating. If you are experiencing higher than quoted NVH with this product, please evaluate the installation to ensure to components are touching each other and email techsupport@034motorsport.com for further assistance.

The factory front upper control arms are an integral part of the B8/B8.5 Audi A4/S4 & A5/S5/RS5, and 95B Porsche Macan 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 Upper Control Arms are designed to be a performance replacement for all four factory front upper control arms. Featuring high-durometer rubber bushings and high-quality ball joints, Density Line 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.

- Complete, Drop-In Replacement for Factory Control Arms
