  • Much less cost than OEM replacement
  • Higher performance
  • Greater longevity
  • Performance durable rubber
  • Less labour cost to replace as a kit
  • Elimination of fluid (which leaks)

The factory front control arms are an integral part of the B8/B8.5 Audi A4/S4 & A5/S5/RS5 suspension, but can start wearing out as early as 60,000 Km - 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 Control Arm Kit is designed to be a performance replacement for all eight of the factory front upper and lower 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.

Features:

  • Complete, Drop-In Replacement for Factory Control Arms
  • Offers Improved Handling Feel & Steering Precision
  • High-Durometer Rubber Bushings (65 Durometer)
  • Includes New M14 Ball Joints (Upgrade for Early M12 Vehicles)

What's Included:

  • Front Lower Control Arms - Front (Left & Right)
  • Front Lower Control Arms - Rear (Left & Right)
  • Front Upper Control Arms - Front (Left & Right)
  • Front Upper Control Arms - Rear (Left & Right)
  • M14 Ball Joints (Pair)
  • Installation Hardware Kit

Please Note: Early (M12 - Build Dates up to Nov 2, 2009). New Outer Tie Rod Ends are sold separately.

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.

Installation Note for C7/C7.5 A6/A7: Since the upper control arms bolt directly to the body instead of a strut mount, the OE upper control arm mounting bolts will have to be reused, or new replacements sourced (N 912 005 01), as the provided bolts are not long enough for this application.

Fantastic Mount especially on rough Roads
Robust and discretely positioned mount. This mount is the real deal. It is by far the highest quality most stable mount that I've ever had in my Tacoma pickup. I also really like that it's positioned closer to the steering wheel in instead of in the windshield, making it easier to view. Very highly recommended!!

Perfecto Product!!
I rarely write reviews, however on this product I need too. This clearly is a pricey phone mount, but after reading so many reviews I went for it & purchased. After opening, I immediately could see & feel the quality of material used. Installation was surprisingly easy & quick to my Tacoma. The mount is very firm, sturdy, very adjustable, perfectly designed product. For as costly as this was, I have absolutely no regrets! Totally can recommend this product to anyone with a Tacoma within the stated production years. So as so many others have said accurately in reviews, I am beyond satisfied even with the cost in mind.

Perfect fit for my 2018 sr5 Tacoma. Great quality!
Extremely well made. Doesn't rattle or slide off. Holds the phone tightly. Finally found a phone mount that works great for my Tacoma (2018 sr5). I highly recommend this product.

5 Stars with 1 Call-Out….
SOLID built like a tank! Really like the all-metal design. No vibration on the road and minimal if any off road, extremely stable. 360 adjustability = endless options on positioning your phone. Overall a good buy considering fit, form and functionality as compared to the less expensive composite holders that shake move and rattle (Drives me nuts). The ONLY negative…. I have a pro max iphone with a case and there’s no way one-handed operation works to insert and remove the phone into the holder. You can use one hand to adjust the angle and positioning but not otherwise. An OFI for OffRoam, incorporate a tension adjustment into the design for ease of insertion and removal of the phone (without breaking the bank). Taking all things into consideration the pros far outweigh the cons! Best unit out there for Gen 3 Tacoma owners.
