Predator built this 2000 Hummer H1 at their company in Vista, California. In the engine bay they swapped a 6.6 L Duramax (LBZ) turbodiesel V8 capable of 450 hp and 900 lb-ft of torque. The motor features an alternative-firing camshaft, ARP head and main studs, Garrett VVT turbocharger with a Wicked Wheel compressor, and 4-inch exhaust. Behind the massive V8 is a Stage 4 Allison 1000 six-speed automatic transmission, Predator HD transfer case, and factory axles with 12,100 lb axles. The company also upgraded the brakes to their Alpha 12-inch kit. The outside features a heavy duty LED light bar, front winch bumper with Warn 12,000 lb winch, D-Ring brush guard, and Kevlar bed coating.
