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)

The really work!
Bought these or a friend with severely dry cracked feet. The change was significant and immediate. They wore them around the house for a day and that night they could already feel the difference.

Fabulously bizarre and effective
These silicone socks have to be the strangest item I have ever ordered from Amazon. However strange they are, I was pleasantly surprised with them. My order came with two pairs, and I took one pair out to wash before use. I laughed at handling them then because they were a cross between hospital socks and leftover mannequin skin…trippy. The socks dried fast, so I put on foot lotion and put the socks on. The socks are beige skin tones that cover the entire foot up to the ankle, basically booties. The silicone is very soft and makes putting on and taking off the socks easy. They are also surprisingly easy to walk around in because the bottoms have grips, again, like hospital socks. I walked on tile, hardwood, and carpet with no slipping. The booties also stayed in place with no issues. I was concerned my feet would sweat, but that didn't happen. I was able to wear them for 3 hours without sweaty feet. When I took them off, my feet were a lot more soft than before or if I had used regular socks. For reference, my feet are not terrible, but the skin around my toes is dry and peeling from my picking(gross, I know). The socks I got are a size large, which worried me because they are big, but the site said for my shoe size (9) that's what I should order, and they were right. They are the perfect size and stretchy for room. I can't believe how cool and well-thought-out these socks are, on top of working. Honestly, these are among the top 20 favorite items I've ordered from Amazon. They may look incredibly strange, and they are, but they work wonders.

So excited for results, feels like it’s working!
Size: Medium, Unit Count: 4
First time trying them right now as delivered today. Originally thought was supposed to wear all night but glad to find out 30 minutes just because my dog sleeps on my feet over my sheets! These silicone socks feel great and I trim my toe nails short enough they seem very durable and unlikely to rip like the pic review shows. I am confident my feet and heels will much smoother after first time wearing! I do have acrylic nails so I will be careful Putting the silicone socks on and off. Just as easy as the video the spread the lotion inside the socks and rub it around, mess free!!

Actually, better than I expected!
Size: Medium, Unit Count: 4
These are better than what I was expecting based on the reviews. I do put them on carefully because someone said you can’t tear them so I’m careful putting them on, but they almost don’t feel like you’re wearing anything as long as you don’t put them too tight on your toes. I can put lotion on my feet and I know it has to soak in because there’s no place else for it to go like socks or my bed.
