Developing a new application is a very involved process that requires a lot of resources. It can take months of R&D, and application selection is based very much on demand (or potential demand). Since the diesel Wrangler and Gladiator are entirely different than their gas-powered brothers, they'll require a completely new design rather than just updating an existing one like we just finished for the 2nd Gen Tacoma. With so few diesels on the road right now, there just isn't the demand we usually like to see for designing a new product. While it is definitely on the short list of new applications, it doesn't look like something that is going to be released in the near future. However, we always introduce a "Waiting List" when we are in the process of designing something new. Be sure to check back in a few months or follow our Facebook/Instagram to be the first to know when the waiting list is opened up.
