I got mine from a company called "top guns customs" poly bushings that are supposed to be a better material. Solid arms, greasable but cant really pump grease in them after install (might get better with time.).
Stock track bar with poly bushings and carli shocks w/ bilstein stabilizer. 2.5" rough country? Soft ride springs. Rides good for being lifted, would be better with an adjustable track bar. I have energy bushings in the front of the leaf's since the stock ones were blown out.
I would go with any non-adjustable arms with poly bushings, extended length if you have a lift.
