Are all FRONT springs the same ( 6cyl and 4cyl ) are they the same i need springs i have a 4cyl i am wondering if the 6cyls are the same as the 4

I have the "dull" answer : Use the seach engine. There is a lot of information about springs, rates, "to cut or not to cut" etc...

Short answer, no. There are several different springs available for the front. Check the build codes for the correct springs.

There are different spring rates based on which suspension was put on. The RPO codes will tell you which suspension you have and what springs.
There are 10 different springs for the front and 8 different springs for the rear.
The first 3 numbers/letters are the RPO codes. These are usually under the front hood on the driver side wheel well.
6HY SPRING, LEFT FRONT
6HZ SPRING, LEFT FRONT
6JA SPRING, LEFT FRONT
6JF SPRING, LEFT FRONT
6JH SPRING, LEFT FRONT
6MF SPRING, LEFT FRONT
6MN SPRING, LEFT FRONT
6PH SPRING, LEFT FRONT
6RC SPRING, LEFT FRONT
6RD SPRING, LEFT FRONT

7HY SPRING, RIGHT FRONT
7HZ SPRING, RIGHT FRONT
7JA SPRING, RIGHT FRONT
7JF SPRING, RIGHT FRONT
7JH SPRING, RIGHT FRONT
7MF SPRING, RIGHT FRONT
7MN SPRING, RIGHT FRONT

8UB SPRING, LEFT REAR
8UC SPRING, LEFT REAR
8UD SPRING, LEFT REAR
8WX SPRING, LEFT REAR
8WY SPRING, LEFT REAR
8XD SPRING, LEFT REAR

while many claim different springs - noone has ever posted actual spring rates. and, overall - if there are different spring packages, the spring rates seem to be so close - you'd never know anyways. especially 20+ years later.

We've never found actual spring rates, but the spring chart gives you an ideal on the relative stiffnesses. At leat you can use the code to see what spings you'd need to go stiffer or softer from where you are.
