Hotchkis leaf springs sagg brand-new

im running a 8.8 explorer rear in my dart sport with hotchkis springs factory rear hangers n i just put front hothkis mounts back in i took em out at first cause it did sit low in the rear but i recently went to 17s up front n 18s in the rear. when i did that n went to a 27" tire the car had a bad rake to it putting the front hotchkis mounts on set it just right i been running the hotchkis springs for about a year with a fair amount of driving. the yoke n drives shaft comes no place close to the floor like yours does i think the dana 60 is goin to be your culprit n how thick are the spring perches on the rear? i have seen various height differences in the mounting heigth of weld on perches that alone has a lift/lowering effect
