I have the non-TSB springs on mine which suck. They are just about worthless and go to the bumpstop on any decent bump in the road.
I added a Wheelers 3 leaf AAL which has greatly helped the ride. They are progressive and control the bumps much better than the factory springs did. They stiffened the ride, but made the bumps softer with less body roll.


Don't just be a survivor, be a competitor.
