There are grooves inside the bushing to keep the grease in the bushing even under heavy load.
Inventory control arms with soft rubber bushings tend to deflect and absorb power under load rather than transfer it to the tires. Compared with the stock rubber bushing, this upper control arm adds a solid and more sensitive touch.
With our upper control arm, it is easier to start, reduce wheel runout and increase cornering consistency for your car.
These grooves also guide grease to the outer edge of the bushing, thus maintaining lubrication of the thrust surface. This effective lubrication ensures quiet and reliable operation of the bushing throughout its service life.
