I have a few 56 spring questions if fellow members don't mind touching on them. Has anyone found best combo of spring packs for best ride with decent towing manners. Is there certain spring packs to look for 5/1 over 8/1? Anything to beware of when seeking set of used ones? Sure there is more info I have forgot but have done little research and know to flip sides on shackle flip from DIY4X. Sorry if some feel like this is beating dead horse but sure you could spend 48 hrs just searching/reading on 56 springs.
