The Rough Country X-Flex front upper control arms are built for performance and durability. The upper joints will pivot up to 20 degrees, and the lower joints pivot up to a staggering 35 degrees. The tubular arms have a 2.5" diameter body and 1.25" threads. The fully greasable joints also feature adjustable retainer rings that allow you to preload the bushings by compressing them prior to installation. Inside the housing there's a threaded chamber that offers the ability to modify the amount of compression on the bushings and friction on the spherical ball. This can be done at any given time by adjusting the end retainer ring with the adjustment tool that's included.
The joints are completely rebuildable for both easy maintenance and adjustments. These upgrades drastically extend the lifespan of the joints themselves. With a few quick twists, your joints will be a tight as the day you installed them. This kit comes complete with the control arms, polyurethane bushings, sleeves and grease fittings.
