Avoid those unfortunate scrapes along your rocker panels when rock crawling by installing these rock rails. They reinforce the thin sheet metal and leave a smooth surface for the Jeep to slide along instead of digging in. Serious off-road rock crawling often means scraping the rocker panels of your Jeep against rocks or stumps. The most immediate issue with that is having a sharp rock dig into the thin sheet metal, and hanging up. That will seriously impede forward progress. Second issue: you’re tearing up your Jeep! Add these RockCrawler bars to reinforce the area. The hardened steel plate and rails will let rocks and stumps slide right along instead of digging in.

Rockcrawler Side Bars
Body Armor® JK-4121 - Rockcrawler Black Side Bars
Like the product overall. In my opinion over priced so if doing it again would shop for cheaper alternative. Was easy install - once you figure out the instructions. (instructions need work). Poorly written and for multiple types of vehicles. You need 2 people to install unless you have a nice floor jack. 4 bolts required were missing for the install. No joke. I was pissed had to make a trip to a real hardware store to get them. Home Depot does not carry. Not happy about that and would like reimbursement which added to the price when you do not have time to jack around with vendor etc. to get them. These are pretty heavy bars which is what you want if buying or else buy something else 45 lbs/90 or both so adds to your gas mileage.
