Both those kits achieve the same thing using basically the same method... both are torsion bar lifts. One just uses spacers with the torsion bar keys bolts to reposition the key, the other uses reindexed keys
What are the tires rubbing on?? A torsion bar lift may make it worse.

Cons of both: Both those kits will twist the torsion bar which in turn will reposition the lower control arm to a steeper angle. This pushes up the front of the truck but it also brings the wheel/tires closer to the frame and sway bar which could make the rubbing worse. You are also losing downward suspension travel and gaining upward.travel,basically changing the resting position of the stock suspension. These lifts also put more angle on the ball joints and tie rods which lead to more wear and tear. Suspension will feel stiffer because of the loss of downward travel. Make sure you get an alignment after you lift it

Pros of both: more ground clearance and looks a little better.
Pros of the Rough Country: it's cheaper, LOL

No other option for leveling kits... its just the way torsion bar suspension works

 

If you really want to level it look up Badland Industries. It's a small company runs by a friend of mine. His kit will be more expensive than the $70 spacers,his kit consists of reindexed keys and shackles but also comes with hardware to reposition the upper ball joint so it's not at a bad angle. This helps with front end alignment and helps with the rough ride by keeping the upper arm from smacking down on metal and cracking

The stock keys work the same as the after market ones do. Like other said, when raising the control arms go in, your front wheels will sit inward more the the rear wheels will, others will never notice but you may since I mentioned it, sorry some installed wheel spacers on the front







these guys were the go to guys for the 2004-12's before the new colorados
