034 Motorsport - Audi B9/9.5 A4/S4/RS4/A5/S5/RS5 Street Density Lower Control Arm Kit  - 034-401-1069

034 Motorsport Density Line Lower Control Arms for Audi B9/B9.5 A4/S4/RS4 and A5/S5/RS5 models replace your vehicle's aging, worn lower control arms with performance-engineered Density Line units to improve handling precision beyond factory levels. Density Line Lower Control Arms replace the factory fluid-filled bushings with Density Line 65 durometer bushings.

  • Replace worn factory parts
  • Performance engineered
  • Improved handling and precision
  • Increased longevity than factory
  • Rubber for performance and comfort
  • Advanced quality accompanying hardware
  • Elimination of fluid bushings (which leak!)

This kit includes four lower control arms, two new ball joints, and all necessary hardware for installation. Perfect for use with 034 Motorsport Density Line Adjustable Upper Control Arms!

The factory front lower control arms are an integral part of the B9/B9.5 Audi A4/S4/RS4 and A5/S5/RS5 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.



034 Motorsport's complete Density Line Lowers Control Arms are designed to be a performance replacement for all four of the factory front lower control arms. Featuring high-durometer rubber bushings and high-quality ball joints, Density Line Lower 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.

FEATURES:

  • Complete, Drop-In Replacement for Factory Lower Control Arms
  • Offers Improved Handling Feel & Steering Precision
  • High-Durometer Rubber Bushings (65 Durometer)
  • Solid Rubber Bushings Eliminate OE Arm Bushings Fluid Leaks
  • Includes New Ball Joints

WHAT'S INCLUDED:

  • Front Lower Control Arms - Front (Left & Right)
  • Front Lower Control Arms - Rear (Left & Right)
  • Ball Joints (Pair)
  • Lower Control Arm Installation Hardware Kit

REALLY unsafe to walk around in these
Size: 2 pairs black L
They do what they are expected to do, but should only be used if you are stationary. The gel base makes for very unstable footing if walking around

These work
Size: 2 pairs black L
My husband loves these they help his very dry feet. As others have stated they are extremely difficult to walk in so have to be careful but they do work nicely.

Potential Fall Risk
Size: 2 pairs black L
While these socks do indeed help soften rough skin on your feet, there is a risk of falling while wearing them. Although they have treads on the bottom, which would indicate they’re safe to wear with nothing else, when you put moisturizer on and then wear them your foot can slip inside the sock . This causes you to lose your balance and fall, which happened to me. I’ve thrown them out.

I could be a foot model now!!!
Size: 1 pair black L
I wear work boots almost all of the time so I bought these to put on my feet with salycylic acid to moisturize and try to get rid of a stubborn corn on the ball of my foot. It helped drastically after a few nights of lounging in the house with them on.

Works for foot psoraisis
Size: 2 pairs black L
Got these for work (service industry) to reduce issues with psoriasis and blisters while putting on 20k+ steps a day. Over time the wounds healed and I could work without so much pain. I now don't use them all the time like I used to, only when a new lesion or blister appears, too prevent a breakout. Tip: if you're not in full breakout, wear thick socks under these as a barrier to friction.
