Leveling Suspension Mods for a 2014+

[gmyeah]

I have a 2008 1/2 sierra z71......and honestly I hope it runs forever. Really like it. My only beef is that the suspension isn't quite beefy enough. I guess I can deal with the towing capability, but the payload should be more in my book. Shortly after I got my '08 new.....I modified it with a set of super springs in the back and a 1.5" leveling kit up front. I also have upgraded the shocks (all around) with Bilstein 5100. I can't stand the lower 'nose-down' look that everyone talks about. It makes the trucks looks so....so crappy. But in the same breath, I use a truck as a truck and need suspension as well......payload, trailering, etc. This truck really gets used. If I were to buy a new one and want a bit more payload capability...what do folks suggest. Also, as far as the 'nose-down' issue....I see that Bilstein has a 5100 series-like adjustable shock for the front. I would imagine that might be better for the trucks suspension than my leveling kit. Either way....I'd like more capability than my super springs are giving me now....
