Adding An Inch

OK so right now im sitting at about 4 inches. I wanna throw in a .75" coil spacer and a JKS shock Conversion kit (already have) but in the rear im running a mixed AAL... works good and and flexes well. Now im worried that if i throw a 1 inch shackle in the rear, its gonna destroy my packs..... will they??

a shackle will only help improve your flex

flat spring packs flex the best
