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

  • Front Lower Control Arms - Front (Left & Right)
  • Front Lower Control Arms - Rear (Left & Right)
  • Ball Joints (Pair)

Good value, soft and comfortable
Color: Black, Army Green, Light Gray, Size: 4X-Large, Color: Black, Army Green, Light Gray, Size: 4X-Large
Initial thoughts are very positive with this 3 pack shirt set. The green is similar to an OD military green and the black and gray are standard color shades. Material is soft and sizes are true to size. The mock turtleneck isn’t too tight but may still be a little annoying to some people. I do question the amount of spandex in these shirts. Tag says 5% but these shirts are extremely stretchy and feels like a higher spandex content. It’s also a little tough to figure out which way is the front of the shirt. Visually rhe front does have a lower collar line than the back but would still be nice to have a brand tag printed in the back of the shirt for quicker identification. Overall for roughly $12 a shirt these are a good choice for everyday wear. I will update rating if these shirts fail to meet expectations after further use.

Just what I wanted.
Color: Black, Navy Blue, Wine Red, Size: 5X-Large
These may have just become my standard shirt to wear. Feels good whether tucked or out. Drapes well and fits well. So far, I can see it adjust to the different undershirt I may wear. Will probably order another set in other colors and a back up set of the basics because they will get worn a lot.

Its alright
Color: Black, Size: 5X-Large
True to size per the size chart. The fabric is soft but it it feels cheap to me. It attracts lint but you can brush it off easily so its not the cheapest material I've dealt with. Also, it is opaque (not see through). There is no front/ back indicator either which is indicative of a cheap shirt in my opinion. Would be friendly for tag sensitive people (to stay positive).
