Bearings Bushings-911 Monoball Cartridges for Trailing Arms sealed (Pair) 1965-89
Today's sticky tire compounds generate corner loads that easily compress factory rubber bushings causing wandering alignment settings. Camber and toe flop around predictably.
Monoball Cartridges replace compliant factory rubber bushings with hardened-steel spherical bearings. Unlike poly bushings that bind and resist movement, true spherical bearings allow free motion on multiple axis.
Cartridges are available for rear trailing arms and front strut tops.
Our proprietary-design Monoball cartridges have optional weather seals to keep dirt out and extend product life.
This is the only Monoball suitable for street or extended track use. Dirt and water contaminate ordinary products and accelerate wear.
