Sphericals™ performance bearings deliver a new level of handling and ride quality. This is the only performance bushing replacement that delivers ball-type spherical bearing action with stock front control arms.
The secret is in the ball-shaped bearing that allows continuous self-alignment, preventing binding and allowing the suspension to work and move freely. Springs and dampers do their job of controlling the suspension without interference from excessive friction or binding from the bushings.

Sphericals Eliminate Binding
With ordinary performance bushings, binding happens when the axis of the front and rear mounts are not collinear. Their hard-compound and minimal compliance cause even minor misalignment of the mounts to pinch and bind, preventing free movement of the control arm. Binding can happen in both static (car is stationary) and dynamic (chassis is flexing) conditions. Sphericals eliminate binding
Dynamic Binding
Dynamic binding is due to chassis flex. This happens anytime the car is cornering, braking, accelerating, or going over bumps. Control arm mounts move with the chassis flex, deviating from their static alignment to cause binding, pinching and resisting free movement of the suspension. The chassis flexes when you most need free suspension movement; to absorb bumps, and during hard cornering when you need grip for performance.
