im haveing trouble with my trail arm to chassis bushes splitting,ive tried the flo flex orange and the polybush orange bushes and niether have lasted very long,ive got a 2" lift,adrenalin 4x4 double cranked trail arms,+5" terrafirma shocks and x eng spring extenders,i know the obvious route would be to fit rose or johnny joint arms but with a few other projects going at min funds wont allow,i would have thought that with only +5" shocks the polybushes would stand up to this amount of flex,does anyone have any tips that would prelong the life of the bushes or is rose/johnny joint the only way to go? and if so has anyone had any experiance with them on the road(i use my truck about 30% on road 70% off) thanks
