034 Motorsport - Density Line Upper Control Arm Kit - Audi B9/B9.5 A4/S4/A5/S5/RS5 - 034-401-1072.

Replace your vehicle's aging, worn control arms with these performance-engineered Density Line Upper Arms restore feel and improve handling precision beyond factory levels. 

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

034Motorsport's Density Line Upper Control Arm Kits are available as Adjustable or Non-Adjustable Control Arms, and are designed to be performance replacements for all four of the factory front upper 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 track driven vehicle.

The factory front control arms are an integral part of the 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. 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.

DENSITY LINE NON-ADJUSTABLE CONTROL ARMS:

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.

INSTALLATION & WARRANTY:

Installation:

  • 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.

Warranty:

  • 1 Year Limited Replacement Warranty (If you encounter any issues with our products outside of the warranty period, we will work with you to provide a resolution.)

Well built
Well made product. I have an volvo xc60 and it fits the oil filter housing perfectly but because of its thickness, there's some interference with the heat shield or it could be part of the skid plate assembly that is next to the filter housing.

Fast delivery and good quality part
Good quality snug fit. Works as should. Only issue I had was whe tightening oil cap back on the 18 ft-lb torque made this part slip. I used material to get a better grip and torqued slow but it still slip before the torque gauge read 18.5 No leaks! So it’s all good 😊
