Under the hood is fuel-injected 2.4L Toyota I-4. Modifications include a Toyota T-100 oil pan (which is a rear sump design and needed for the solid axle conversion), Downey Off-Road header, and Flowmaster muffler. An Optima YellowTop battery helps provide electrical current. The engine is mated to a Toyota five-speed manual transmission that has a Clutch Net Stage 4 clutch. Dividing power to the axles is a dual Marlin Crawler T-case setup with 30-spline output shafts and 2.56:1 and 4.70:1 gearing.
