By Trailblazer coils, I meant lowering coils for a Trailblazer. Although, stock TB coils would lower a Tahoe, just very minimally. IIRC, the coil to have is the DJM 4" Trailblazer coil and it'll yield around 5" of drop on a Tahoe. If this is too much, you could toss in a 1" spacer. If it's too soft or if you tow, you could add some Airlift bags. I think the bags to use are for a Nissan Pathfinder. I have some but not the part number. They're about half the height of the stock Tahoe bags. For a stock or possibly slightly softer than stock ride, Belltech Street Performance struts and shocks are the ticket. The Belltech struts come with rings to adjust the drop from 0" to 2" in 1/2" increments. I was thinking 4" front drop might be too much so I was gonna try 3.5". I don't wanna have to take the struts back apart if it's not enough drop. So, I'm gonna go with no spacers to get the full 2" drop (4" total with the McG spindles). If it's too low, I'll use a spacer under the strut just like a lift spacer to fine-tune the drop. An 1/8" thick washer would yield about 1/4" of lift.
