I don't believe they offer them for the 2006-2009 Ram 1500's. The Cut-Out style flares require you to cut the inner and outer fender. On some trucks this fender supports the battery tray, power distribution boxes, etc. That makes cutting the fender next to impossible. On the 2006-2009 Ram 1500 the headlight shape also makes cutting the fender "higher" a tough job.
We can call Bushwacker on Monday but my guess is they don't offer the Cut-Out for your truck because it's just not compatible with it.
