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.

DENSITY LINE ADJUSTABLE CONTROL ARMS:

Featuring high-durometer rubber bushings, high-quality ball joints, machined-billet upper adjustable control arms, and Aurora or FK spherical bearings, this kit is engineered to limit unwanted deflection in the suspension. 034Motorsport's Density Line Adjustable Upper Control Arm Kit replaces the fixed factory front upper control arms to allow for precise, independent camber adjustments. Density Line Adjustable Upper Control Arms for the B9/B9.5 platform are available in two versions depending on your specific needs.

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.

Functional. Be careful when tightening nuts...strips very easy
Quality is questionable. The poles will strip way to easy. So be careful when fighting down. I had to use a stack of washers on top of wire to keep the nut tight. As far as functionality goes ..been doing great for over a month.

Heavy-Duty 4 AWG Cable With Flexible Insulation
Size: 10ft, Color: 4awg
I am satisfied with this 4 AWG cable. The insulation coating is soft, and the cable itself is very pliable, making it easy to bend and route into the configuration needed for installation. Despite the flexibility, it still feels like a heavy-duty cable designed to handle demanding applications. I am using this cable to provide the necessary amperage to start the generator on my trailer, and it performs as expected. I also like that the wire gauge and cable properties are clearly printed along the side of the insulation, making identification easy during installation or future maintenance. The cable arrived in good condition with no obvious odor from the insulation or packaging. Overall, this appears to be a quality heavy-duty cable that is flexible, easy to work with, and suitable for high-current applications.
