how much to cut off the spring for 6" drop in the rear
I want to just cut my rear springs down when they say 6" drop do they just cut off 6" of spring when its un compressed. I figured that wasn't the case but after you load the spring up the truck will drop 6". I would like to know if anyone has cut there spring and how much did they cut off I dont want to take them off again after I cut them. The truck is a 67 shortbed. I put the 2 1/2 spindles/ and 2" drop srpings in the front.

Re: how much to cut off the spring for 6" drop in the rear
You can't cut the rear coil springs. (I'm assuming that's what you have) The top and bottom of the coils are pigtailed to allow them to be bolted to the frame and trailing arm. If you cut one end of it, they won't stay in place.

Re: how much to cut off the spring for 6" drop in the rear
You can cut the rear springs if you can make a retainer to keep them from moving around. We did this on a couple of my buddies previous trucks when we were young guns.
That being said, we only did it because they didn't offer drop springs like what's available these days (back then, heating the coils was how most guys we knew dropped the rear). The trucks didn't ride good because most of the coils effectiveness was removed. GMC Pauls has drop springs from 2-6" for less than $120. I prefer using lowering blocks to help maintain overall shock length, so I would do 4" spring + 2" blocks. You could make the blocks pretty cheap (look in the FAQ section for the info) or if the budget is that tight, just go w/6" springs.

Is it safe? I doubt it. On the first 69 my buddy had (that had the rear coils trimmed), the coils were actually welded to the trailing arms to make sure they didn't move. The 2nd 69 he had is where the 'cups' were made to keep the springs from moving.

I just bolted the bottom of the spring and mount to the trailing arm and left the frame sitting on the top of the spring.

Re: how much to cut off the spring for 6" drop in the rear
I was just saying that I remember back in the day when this was pretty much the norm . Bad thing about it was that the truck would bounce off the street if you hit a bump. Now days most people still have the idea that if its lowered the ride is crap. If its lowered it should drive if not the same then better then before.
