Front drop coil spring

I have a 68 swb gmc with a sbc . I have lowered the truck by flipping the rear and using 21/2 inch drop spindles . IT still needs to come down in front at least another inch or two . I have the stock springs in now and maybe could cut them for this but I have never cut springs before and don't know what all is involved. The old springs have at least 100 k on them . Do you really get the one or two inch of drop with new drop springs ? If anyone suggest cutting please explain what needs to be done to the top and bottom of the spring. Thanks

Re: Front drop coil spring

the old springs are 40 some years old and tired, therefore they will droop whereas a new drop spring will not. if you need to drop another inch in the front, youll most likely want 2" drop springs if not 2.5'
if you decide to cut the originals, cut only 1 coil. this will give you about 1.5 to a 2" drop. use a cut off wheel

Michael, I knew how to cut them . but was under the impression you had to do something to the top to get them to seat correctly , thanks for the reply .I ordered a set of 2 inch drop coils today and I will update on how much drop I get. thanks again

Re: Front drop coil spring

I got the 2inch drop Mcgaughy's coils and installed them . I have their 2 1/2 inch drop spindles with new rear springs and a flip kit in the rear front of truck went down 3 inches in front .I was measuring from floor to top arch in front fender. With stock springs I was at 291/2 inches with 2 inch drop springs I went to 261/2 inches that made it to low. I reinstalled stock springs truck is almost level. I am going to leave it until I get it done and adj the front then. Thanks for the pic.
