56\" shackle flip rear spring guys The K5/K10 project is going to get a shackle flip using the front spring hangers out of a 1/2 ton pickup. I have a set of 56" rear springs out of a 77C20 HD. 9 leaves plus overload. I figure between the shackle flip trying to even out the lift gained with the 52s in the front combined with the rear spring hangers moved back it'll do a good job of protecting the gas tank. But, how many leaves do you guys remove? Which ones? What's the general consensus of how far to move the rear spring hanger back?
