PRODUCT DESCRIPTION:
034Motorsport's complete Density Line Control Arm Kit with Upper Adjustable Control Arms is designed to be a performance replacement for all eight of the factory front upper and lower control arms. Featuring high-durometer rubber bushings, high-quality ball joints, machined-billet upper adjustable control arms, and Aurora spherical bearings, this kit is engineered to limit unwanted deflection in the suspension. 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.
