I have a 04 Tahoe with 2 inch mcgaughy spindles up front and 3/4 ton purple keys. I've had crown 4 inch coils. Mcgaughys 3 and now I have trailblazer coils. Part number 4230. They are the best so far they just bottomed out easy so I put in 60748 helper bags in them an its awesome now

In your pic do you have the spacer with the spring or is that spring only?
