Outer Limits 4x4 Board

Am looking for a better ride and bit more flex out of my sierra. I know a lot of people take out a spring from the pack but ave a few q's.
1. Which spring do people reckon you should take out 2, 3 or load?

2. do you take the spring out from front AND rear packs? and if so do you take the same leaf from front and back.

cheers nev.

I ACQUIRED THREE INCH LIFT SPRINGS FOR MY ZOOK WHICH WERE ROCK HARD SO I REMOVED NUMBER 4 LEAF LONGEST LOAD LEAF WHICH WAS NOT ENOUGH THEN I TOOK OUT NUMBER 3 AS WELL WORKS VERRY WELL NOW I HAVENT HAD ANY PROBLEMS WITH IT
