There is plenty of cheap crap poly out there. DO NOT BY THE CHEAP CRAP.
Fulcrum Suspension make Super Pro Polyurethane Bushings and export them all over the globe. Highest Quality on the market and the best when it comes to NVH (Noise Vibration HArshness). They are specifically engineered for each application, some bushes are softer than rubber, and some harder depending on aplication. THey are fantastic and also offer Caster Correction Wheel Alignment Bushes. Unfortunately I dont believe they do anything for the KJ though - all other Jeeps yes, but no demand for KJ at all.
