Dual Case Adapter
Introducing our Xtreme Duty MC07 Dual Transfer case Adapter Kit. With nearly 20 years experience in dual cases, we build the strongest and most reliable Toyota dual case setups in the world.
Equipping your truck with our dual case setup will drastically lower your truck's final drive ratio. This is because you will have an extra low range gear set that you can engage. Your truck will be able to move very slowly, even with the clutch fully disengaged, regardless if going uphill or downhill. Through different gear ratio options, the Crawl Box will instantly multiply your trucks final drive ratio. This provides more torque, control, and traction. Torque is increased by a larger gear ratio, control is increased by being able to drive through an obstacle at a slower pace, and traction is increased due to less wheel speed. Your truck will move a minimum of 56% slower, with gearing options available to move your truck up to 2,198% slower than stock! With an optional and crazy triple case setup, the sky truly is the limit!
One great thing about using our dual case setup is that your high range is unaffected. This is because the Toyota high range gear ratio is a 1:1 ratio. Therefore, when our dual case is not needed, it is simply shifted into high range. Once in high range your vehicle is free to travel in the city or highway at normal driving speeds as if our kit wasn't even there. But once you are out on the trail and you encounter a technical rocky section, all you have to do is shift our Crawler into low range and now you are doubled down!
