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.)

Pretty and seems to work but smells odd at first.

Beautiful but smells a little fishy at first. Thankfully the smell dissipates fairly quickly.

Lovely shimmer, but lingering scent and uneven mist are disappointing
Color: 1pc
I love the shimmer in this. And I love that there is spf. But the spray nozzle doesn't provide a fine mist, it's more like a splatter so it's hard to apply evenly. There is also a lingering scent that I find a little overwhelming to have directly on my face. I want to love it, but I'm giving it 3 stars for those issues.

Glitter
Color: 1pc, Color: 1pc
The ingredient list checks out as a sunscreen, but for SPF 50, it seemed too watery from my observation. It was easy to apply because it’s light and watery, but I doubt it’s as effective as it should be. This glowing and lightweight sunscreen also has a faint watermelon like scent, and all those nice oil based ingredients moisturized my skin well. The spray is convenient and easy to use, and I like that about it. However, I am just not a big fan of glittery stuff. Whether it’s on a Christmas card or on my skin, whether I like it or not, it will end up being eaten or breathed in one way or another. Overall, this is an okay product, and I really wish it didn’t have glitter in it.

Summer ready

This is very cute sheer mist for all over body. I’m not sure if it really works as sunscreen because I feel it too watery to apply it nicely all over. I definitely don’t intend to use it as facial sunscreen (I’m trying to protect my face from more dark spots). The mist is very sparkly and I love it. Once sprayed it provides sparkly finish and it looks nice. There’s no smell (or very very mild one) and it absorbs really fast due to it being very watery. Now as someone mentioned the spray part is a bit annoying- it leaves patches of watery spray instead of fine mist. You definitely need to tap it in after spraying which is a bit annoying. I’ll definitely use this as part of my pool/beach routine - probably on top of “normal” sunscreen for all over my body. It adds a bit of hydration too which is nice.
