I have an '07 Silverado Classic that just about scrubs the ground in front. If I was in a lowrider club, it would be great, but I don't like stepping down to get into the stock truck. I am raising the front to match the stock rear, and will do so using either new torsion keys, or coil-over spacers. Between the two, which would have less downside? For my jeep, I went top of the line lift, but that's a different animal. I'm just looking for 2 inches without undue wear on my suspension components. Thanks.
