Are you certain you need extra spring assist up front? Maybe your condition is like I had where the extra weight behind the rear axle lifts the front making it lighter and higher. I addressed the condition through replacing the front coil springs with lighter-duty versions to soften the ride up front along with lowering of the front suspension by 1.25".
CLICK HERE to read all about it. I included a diagram of my weight distribution and before/after pictures.
I previously installed heavy duty versions of stabilizer bars, front steering stabilizer, and shocks to improve handling. The softer front springs actually improved handling a little bit better yet. The rig is more tame since the change in front coil springs.
