Rear Monoball Cartridges

Today’s sticky tire compounds generate corner loads that easily compress factory rubber mounts causing wandering alignment settings. Rear camber and toe flop around along with the mounts.  

Elephant Racing rear monoball cartridges replace the compliant inner trailing arm rubber mounts with hardened-steel precision spherical bearings.  Suspension settings remain stable under the heaviest corner loads.  Driver feedback becomes precise and positive.

Unlike poly bushings that bind and resist trailing arm movement, true spherical bearings allow free motion on multiple axis. Cartridges Install easily into factory trailing arms.

·         Precision hardened-steel spherical bearings

·         Optional weather seals for long life, even on the street

·         Eliminates rubber mount compression

·         Maintains alignment settings through turns
