If you've got a B9 or B9.5 Audi A4, S4, RS4, A5, S5, or RS5, you probably know how crucial those front lower control arms are for your ride. But let s be real if you re pushing your car to the limit, those factory arms can start to wear out pretty quickly, sometimes as early as 40,000 miles. That s especially true for those of us who like to take our cars on spirited drives or track days. Once the rubber bushings start to break down and the ball joints get some play, your alignment goes out the window and steering precision takes a hit.

Enter 034Motorsport s Density Line Lower Control Arms. These aren t just any replacements; they re designed to be a step up from what you had. With high-durometer rubber bushings rated at 65 durometer these arms are built to minimize deflection in the suspension. What does that mean for you? Tighter handling and a steering feel that s sharper than even brand new factory parts.

Features:

  • Complete drop-in replacement for all four factory lower control arms.
  • Improved handling and steering precision that you can feel.
  • High-durometer rubber bushings that won t leak like the OE ones.
  • Includes brand new ball joints for a complete upgrade.

What s in the Box:

  • Front Lower Control Arms (Left & Right)
  • Rear Lower Control Arms (Left & Right)
  • Ball Joints (Pair)
  • Installation hardware kit to get you set up right.
