Who is crazy enough to bring a brand-new Wrangler JL on the Ultimate Adventure? Dana is, but only after installing its own AdvanTEK axles under this Sahara model. Randall Speir was back again this year. He brought his gearhead wife, Rachel, along to shoot photos, serve as trail spotter, and ensure that both he and the Jeep made it through the week in one piece. Speir more than earned the nickname Whiskey Throttle last year piloting the company’s 525hp
LS3-powered JK on UA 2017. After getting comfortable in the more mildmannered JL, he was up to his old throttle-down driving style for UA
2018, prompting some onlookers to assume there was way more under the hood than just a factory 3.6L Pentastar.
