034 Motorsport - Density Line Control Arm Kit - Audi C8/D5/4M - A6/A7/Q7/Q8/S6/RS6/S7/RS7 - 034-401-1082.

Fits Audi C8/D5/4M chassis with various models, check the fitment information. This is the full UPPER & LOWER control arm kit.

034Motorsport Density Line Lower Control Arm Kits with Density Line Non-Adjustable Upper Control Arms are the ultimate upgrade and replacement solution for your Audi!

Replace your vehicle's aging, worn control arms with these performance-engineered Density Line units to restore feel and improve handling precision beyond factory levels. These kits include four upper control arms, four lower control arms, two new ball joints, and all necessary hardware for installation.

034Motorsport's complete Density Line Control Arm Kit with Upper Adjustable or Non-Adjustable Control Arms are designed to be performance replacements for all eight of the factory front upper and lower 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 - even on vehicles that see mainly highway commuting miles, trips to the local mall, and school drop-off/pick-up. 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.

  • Complete, Drop-In Replacement for Factory Upper Control Arms

Installation Note:

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.

Comfortable pillows
Color: White, Size: Standard (Pack of 2)
These pillows are great. Not too soft or to hard. They need to be in the dryer for about 15 minutes to fluff up. Perfect buy!

Don’t judge by the size
Color: White, Size: Standard (Pack of 2)
I don’t write reviews here typically but I’ve been on the pillow hunt for years with no luck. Mine are always lumpy and misshapen or too soft or too firm. Don’t judge this pillow by how it looks though because I saw it and thought for sure I wasted money. They are small and not fluffy at all. But OMG I laid down on it and it’s the most comfortable pillow I’ve had in years. Memory foam didn’t work for me but this simple little pillow just allowed me some great sleep. Very happy with this purchase. It’s a simple, no frills pillow that’s perfect for this side sleeper that doesn’t like a too soft pillow.

Superb!!!!
Color: White, Size: Queen (Pack of 4)
If I could give more than 5 stars I would. I purchased these beauties 6 months ago and they are still fluffy and firm. I'm amazed by the price point. I will definitely re-order for the guess bedroom.

Soft and comfortable, NOT firm.
Color: White, Size: Queen (Pack of 2), Color: White, Size: Queen (Pack of 2)
Overall, these are comfortable pillows for the price, especially if you prefer something soft rather than firm. The pillows arrived vacuum sealed, which is pretty standard. Once opened, they fluffed up well after some time and looked full enough to use. Right away, they felt soft and plush, and sleeping on them was comfortable from the first night. In terms of comfort and support, these pillows are definitely on the softer side. They work well for side and back sleeping if you like a pillow that you can sink into a bit. They’re not firm or dense, but they’re still cozy and gentle on the neck and head. After a few days of use, I did notice that the pillows started to look a little lumpy and uneven. The filling tends to shift, so they don’t hold their shape perfectly and need regular fluffing. That said, even when they look a bit misshapen, they’re still soft and comfortable to sleep on. If you’re someone who needs strong neck support or prefers a firm hotel-style pillow, these may feel too soft. However, if comfort and plushness are your priority, they do the job well. For the price, I think they’re a good value. They’re not luxury pillows, but they’re comfortable, decent quality, and perfectly fine for everyday use or a guest bed.
