I fitted a set of rock crawler HD leaf springs, they have done 26.000kms and I have fitted ARB canopy and custom made drawers (light weight aluminium) and the ass end of my truck is sagging big time!!! It is barley sitting 20-25mm above standard now. So I'm going to replace them as soon as possible, can anyone recommend what HD leafs are good quality and won't sag like these piss weak squeaky rock crawlers??
