PRODUCT DESCRIPTION:
034Motorsport's complete Density Line Control Arm Kit with Upper Adjustable or Non-Adjustable Control Arms and 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 - 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 the front-end feel!
Density Line Non-Adjustable Control Arms:
034Motorsport's complete Density Line Control Arms are designed to be a performance replacement for all factory front 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.
