K5 blazer problem

[SKELLY4x4]

I lifted my 1990 K5 Blazer with a 4" Rough Country lift kit. It has pulled to the right ever since (driving and braking). The kit came with a steering arm. It has been at a reputable alignment shop for about 3 months now. They have replaced all brake parts. The thing has a slight driving pull but a very severe brake pull. It no longer has a bump steer. They had to heat up and bend the provided steering arm. I am about to have them just change lift kits completely since I no longer have the old springs to try. I along with everybody in San Diego am out of ideas. If anybody has any ideas please speak up. I am not the first person to lift a K5.
