Hi. I am looking into getting a blazer and doing it up. Lowering would be part of the plan. I have found a 2004 2 door that I might be interested in. I am looking into parts ahead of time and I can't find any lowering kits for it. I've tried everywhere. Also this truck is a 4x4. Would it be wise to drop a 4x4? How hard are these vehicles to drop? Any answers or input would be greatly appreciated. Thanks.

Lowering a vehicle obviously decreases ground clearance, not a wise move with 4WD. That may be why you can't find parts. There are many companies that manufacture body lift kits for 4WD, a much better choice.
