Toyota Tacoma DUAL CASES!! | Trail-Gear & Sumo Gear CrawlBox Build PART 1

It's time to make this truck into the rock crawler I've always dreamed of owning! To accomplish that, this thing needs to actually CRAWL. In order to make my truck as slow as I need, I've decided to build up and install a Trail-Gear dual case adapter style crawl box, which utilizes parts from an old Toyota Pickup transfer case. While I had everything apart, I decided to also install a 4.7:1 gearset from Sumo gear, which will take this already extremely capable setup and make it into what will likely be one of the slowest trucks on the rocks. This will be a two part series, just due to the amount of work required. I hope you guys are as excited as I am!
