First - I believe the wheel house is the same on Blazers and Fleetside PU (subs are different).

Second - Why do you want a lift & what size tires are you going to run? Lifts don't all measure the same from manufacture to manufacturer. The same holds true for tires - some 35's are only 34" tall, others are 35" tall.

I have approx a 4" lift (installed by a PO) and I'm running tires that are 31.5" tall. My truck fits in the garage with about 1.5" to spare. The Blazer I had before this one had 6" of lift with 35's and it was about 4" too tall to fit in the garage. My current Blazer is a much smoother and truer tracking ride. The one with the big tires had a lot of bump-steer and was a challenge to drive at freeway speeds.
