Purchasing Instructions: Select the correct version based on the following:

• Density Line (Non-Adjustable): Direct replacement of the factory control arms, performance-engineered with Density Line bushings to restore handling precision beyond factory levels.

Luxury performance SUVs like the Audi RSQ8, Bentley Bentayga, Porsche Cayenne and Lamborghini Urus are celebrated for their commanding presence and impressive power, but their handling performance often comes at the cost of suspension comfort and precision. The factory front control arms are designed to prioritize a smooth, compliant ride, but as they wear out, often as early as 40,000 miles, steering responsiveness and stability can decline, especially under spirited driving conditions.

Engineered as a direct replacement for the factory front control arms, Density Line Control Arms feature high-durometer rubber bushings along with premium ball joints to significantly reduce unwanted suspension deflection. This translates to a level of precision and handling performance that is truly befitting of the world’s finest luxury SUVs. The result is a front suspension that feels as smooth and refined as the factory setup, but with significantly enhanced durability and control, giving you the confidence to push your SUV to its limits on the street, backroads, or track.

The factory front control arms are an integral part of the suspension, especially on enthusiast-owned vehicles which are driven hard on the street, backroads, or the track. As the rubber bushings degrade and ball joints develop play, alignment is compromised and steering becomes less precise. This kit is a drop-in replacement with feature improvements over stock, that will tighten up front-end feel and allow camber adjustment to significantly improve handling. With 034Motorsport’s Density Line Control Arms installed, you can enjoy the perfect synergy of luxury, performance, and reliability.

034Motorsport’s complete Density Line Control Arm Kit with Non-Adjustable Control Arms are designed to be performance replacements for all eight of the factory front upper and lower control arms. The result is tighter handling and more precise steering response than even brand new factory control arms can offer. In addition, adjustable upper control arms allow optimal alignment for your lowered or performance driven vehicle.

Installation Note:

It is imperative that the suspension be compressed to static ride height before any suspension pivot bushings are tightened, as per the factory installation procedure. If this is not done, the bushings will tear prematurely as the twisting forces on them will be much higher than is intended. 034Motorsport’s Limited Warranty on Density Line products does not cover premature failure due to improper installation or use. We highly recommend professional installation for this product.
