I dont know for sure, but if you dont own a 18 deserthawk I think it's safe to say some modifications are needed. I highly doubt they'll be as much as putting 30 holes. I just want the OEM set because they are OEM and I don't want the tube stick out. I like the flush clean look
Looks like you can get them in a kit from MOPAR Direct.

Im selling my DesertHawk rockrails if you want them. $400. Renegade only had 21k on it when I removed them and these have 0 damage. I bought the Renny from a single older female who mall crawled it. Im in Raleigh NC. These things are friggin solid!!! Very impressed with build quality of these. Mopar did a good job for sure. I just dont rock crawl and enjoy having the jeep look taller from the side.
