Im working on gradually restoring the K5 and my stock springs are pretty bad. She's got the saggy butt syndrome by about 2" on level ground, and the front springs feel like there almost too stiff. I figured that if im going to spend money on springs, might as well put on a small lift and have room for 35's if i decide to not go back with 33's. Im looking to get the softest riding 4" lift possible without too much driveline butchering, like going with longer springs and such. Im about 80% on road and 20% off, so im not looking for extreme articulation...just a really nice soft ride. She's not a crawler and most of my wheeling is on dirt trails with some mud. I thought about maybe a flip for the rear and some zero rates, but im not sure if its going to cure the rear sag or not. Whats the softest rate front 4" lift spring you guys can recommend to me? BTW i know i COULD fit 35's on stock suspension, but seeing how my truck is in really really good condition without even the slightest hint of surface rust.....the sawzall isn't getting within 100 ft of my truck I also have to keep price into perspective, so custom springs are out of the question. My funds are getting sucked out from the LS1 transplant.
