Installation Effort: MEDIUM
NVH Levels: None-Low

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 the components are touching each other and email techsupport@034motorsport.com for further assistance.

Product Description:

The factory front lower control arms are a critical component of the C8 Audi suspension system and can begin to show wear as early as 40,000 miles, particularly on vehicles driven daily in demanding conditions. Over time, the factory rubber bushings soften, and the ball joints develop play, leading to reduced steering precision, compromised alignment stability, and a less connected driving experience.

034Motorsport’s complete Density Line Front Lower Control Arm Kit is engineered as a high-quality, long-lasting replacement for all four factory front lower control arms. Featuring high-durometer rubber bushings and premium-quality ball joints, these control arms are designed to provide improved durability and maintain suspension geometry more effectively than the factory components, all while preserving the comfort and refinement expected from the C8 chassis.

As a complete replacement solution, Density Line Lower Control Arms are a cost-effective alternative to OEM control arms, offering upgraded materials and improved longevity at a competitive price. By reducing unwanted suspension deflection without introducing harshness or noise, they restore crisp steering response and confident handling feel, making them an ideal OEM+ upgrade for enthusiasts seeking enhanced reliability, durability, and driving precision.
