[low sierra]

cut one coil off the front springs on my 79 in july of 81 and it is still working very well. used a flip kit on the rear and was not satisfied with the results because the rear was lower than the front. to get the front end down more I cut another 1/4 coil off and it was way to much causing lower ball joint problems, don't go past one coil. put in new springs cutting 1 coil again and took the truck and a new set of MOOG lower ball joints to the alignment shop. when I got it back the new ball joints had lowered it about another inch. it was perfect ratio front to rear, just a slight forward rake.
by the way when I ordered the flip kit, first I had ever seen advertised, the instructions told me to cut front springs and remove all the bump stops front and rear.
sorry for the long story, hope this helps.
I forgot to say that I heated and flattened the bottom of the spring as well.
