This is sales spiel, but it is relevant and explains more about what is happening when you use + keys;

for the money spent, I think the Cognito kit that replaces the upper control arms linked above is the best deal. I would be doing these in a heartbeat if I wasn't looking at doing other things.

I emailed with the guy that owns Cognito and discussed this and it's the best option for stock trucks. It will bring the front of the truck up without the harsh ride and with longer travel shocks, be more efficient even when off-road.

It changes the geometry just slightly while offering that slight rise to the front. That change in geometry keeps everything correct up front while simply over torquing the torsion bars does not and will cause premature wear and the harsh ride.

I am trying to get them to make more things for our front end to make it stronger because they have the GM IFS figured out.
