Storage, protection and towing capability. There are plenty of new accessories for the 2018 Wrangler JL to help augment all three of those categories for those who wish the added capability.
Components such as factory Mopar roof racks will directly integrate with the JL Wrangler's hard top to provide additional storage options, while rear cargo baskets help add handy internal storage space. For those planning on changing out their stock tires to something larger, oversize tire carriers and reinforcement kits are certainly beneficial. Also, aftermarket front or rear bumpers can add protection over the factory versions, while a new tow hitche can give you that necessary tow capacity for camping or weekend adventures.
