i use 5.9L springs but I straightened the pig tail portion instead of cut them off and I got 3 inches of lift when theres no weight in my truck. about 2.5" when its loaded/steel bumper
I pulled of some rear coild springs off of a 1995 jeep grand Cherokee ( V8 model only ) they fit. all you need to do is cut off the pig tails. and surprisingly enough they were the same size as my old springs but with the more dense coils it lifted the rear of the vehicle about 2.5 inches.
