I hard of a guy that bought some neoprene rubber off eBay and made his own gap guard . It wasn't a whole wheel well like cjs got but I'm sure it would help and it seemed cheap and u make your own. Nice looking though cjs

 

I actually bought the PA gap guards for the first truck of mine I put a body lift on. Saw what they were for $100 and on the next two trucks made my own out of rubber flooring material, looked just the same and cost about $25 for a 10' roll.

I've thought about going to get a roll and making something up, just one of those "back burner" things...
