Sphericals™ Springplate Bearings

Sphericals™ Springplate Bearings

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 rear springplates.

The secret is in the ball-shaped bearing that allows continuous self-alignment, preventing binding and allowing the suspension to work and move freely. Springplates and swaybars do their job of controlling the suspension without interference from excessive friction or binding from rubber bushings.

Sphericals Eliminate Binding

With ordinary rubber performance bushings, binding happens when the springplate mounts are not aligned on each side of the car. Their hard-compound and minimal compliance cause even minor misalignment of the mounts to bind, preventing free movement of the springplate. 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. Springplate mounts move with the chassis flex, deviating from their static alignment to cause binding, pinching and resisting free movement of the rear suspension. The chassis flexes when you most need free suspension movement; to absorb bumps, and during hard cornering when you need grip for performance.

Static Binding

Static binding is due to factory chassis mounting points (welded bungs to sheet metal) that are imprecise at best and can be substantially off due to corner impacts, pot holes, or suspension pan replacement. If these imprecise mounts are not collinear, the springplates will bind even when the chassis is not flexing.
