OVERVIEW

The Cusco Rear Upper Control Arm Pillowball Bushing Set upgrades the compliant factory rubber bushings located on the inner body mounting side of the rear suspension setup. By switching out elastic factory rubber for ultra-rigid spherical bearings, this set locks down the inner pivot junction of the rear upper control arm. This zero-deflection hardware layout stops rear suspension alignment changes under extreme load, giving drivers instantaneous track feedback, highly predictable weight transitions, and consistent tire contact patches during aggressive track cornering and hard braking.

FEATURES

• Replaces compliant factory inner rubber bushings with zero-deflection spherical pillowball bearings
  
• Maintains precise static and dynamic suspension alignment geometry under high cornering loads
  
• Preserves vital multi-axis suspension articulation while removing undesirable lateral and longitudinal flex
  
• Includes specialized external rubber dust boots to lock out track grit, dirt, and wet weather elements away from the bearings
