hey everybody. i just got back from my local spring shop. my rear leafs are really sagging.the guy at the shop said he would build me the same as stock leafs with a 1 or 2in lift in the leafs to compensate and make the truck sit level. i have 4in blocks in the rear.what should i do??? a 1in or 2in lift in the springs to make it sit level???. the shop said the truck would ride better with close to stock springs and that there is nothing wrong with having blocks.they said if i get 4in lift springs it won't ride as good. please help i need rear leafs soon as i just snapped a leaf in the rear this past saturday.
