Control Arm Bushings

Whiteline Performance Control Arm Bushings (Model W63664) are precision-engineered suspension components designed to restore or upgrade the connection between your control arms and frame. Over time, factory rubber bushings deteriorate from heat, UV exposure, and constant flexing under load—causing excessive play in the suspension geometry and degraded steering response. These replacement bushings address that wear, delivering tighter steering feel and improved chassis control for both street and spirited driving applications.

Whiteline's control arm bushings are engineered from high-durometer polyurethane that resists the compression and cracking that weakens stock rubber over thousands of miles. Polyurethane material maintains stiffness across temperature swings and resists oil contamination, ensuring consistent suspension geometry alignment throughout the lifespan of the component. The compact design—measuring 5.3 x 2.5 x 7.45 inches and weighing just 1.22 lbs per bushing kit—allows direct bolt-on installation without modification to mounting brackets or control arm geometry. This material choice increases response precision compared to worn factory bushings while remaining street-friendly for daily driving.

Mechanics and enthusiasts performing suspension restoration or geometry upgrades will benefit most from these bushings, particularly when combined with control arm or steering component replacement. Installation requires standard hand tools and basic suspension knowledge—the bushings press into the control arm mounting points and frame attachment locations. Verify fitment with your vehicle's year, make, and model before purchase, as control arm mounting geometry varies across platforms. Once installed, expect noticeably reduced play at the steering wheel and more direct response through corners compared to aged factory components.
