Under normal circumstances i wouldn't use blocks but stock it sits so high at the rear that I don't think re-set springs alone will do it....

I'll get the springs re-set and take it from there. The truck is going to be a daily driver and will on occasion carry heavy loads (engines etc). My concern was that the helper leaf doesn't come into play until the truck is loaded normally so you get a decent ride until it's loaded up. Re-setting the springs will mean the helper leaf is permanently in contact. I guess there's no way around that. If nobody's found it to be a problem though that all good

If I do have to use blocks as well and windup becomes a problem I suppose I could add radius arms or an A frame above the diff as there plenty of room. The ute looks like it would be pretty easy to four link under the rear although there's limited room for coilovers. Not sure i want to go that far on it though. I've already got my work cut out doing the body
