Synergy Suspension Dual Durometer Bushings
Kar Kraft Engineering ® is on the forefront of leading product innovation. Kar Kraft worked with a suspension manufacturer to develop a high articulation dual durometer busing as replacement to heim, Clevite bushings and Johnny Joints®. How do you replace the segment leader? With disruptive technology.
Kar Kraft’s off road experts set the standard high by crafting industry defing KPIs: 32° degrees of articualtion, grease free, low NVH, maintenance free, no gaping and self-centering. The result? A teglow impregnated dual duromter bushing that offer high articualtion and has bump stock to clock movement.
- Synergy Dual Durometer Bushing (DDB) Series
- Feature a maintenance free, grease less design.
- Self centering with 30 degrees of misalignment. (4320-01, 4320-02, 4320-03)
- Outer “soft” durometer acts as bushing cushion and flex material.
- Inner “hard” durometer lining acts as the bearing surface to allow free floating inner sleeve to rotate. Provides for a maintenance free “zero bind” bushing.
- Internal bushing ring separates inner and outer materials to prevent inner sleeve gaping at extreme flex.
- Direct replacement available for OEM Clevite style lower control arm bushing.
- Bushings available for all suspension components made by Synergy MFG as well as many other companies.
- Bushings are sold complete with inner sleeve installed.
