Behind the Ram Jet 350ci sits a three-speed TH350 transmission. A TCI 1,200 rpm stall converter helps deliver power, while the Flex-a-lite auxiliary cooler keeps fluid temps in check. Adding to the versatility of the rig is a two-speed Atlas II transfer case from Advance Adapters. The gear-driven T-case is fitted with a 3.0:1 low range ratio, which offers plenty of low-end grunt to crawl in the rocks, and enough wheel-speed potential to make it perform in the sand or mud. J.E. Reel 1350 driveshafts connect the T-case to the axles.
