Give your H2 a 6.6L Duramax Diesel Engine, Allison Transmission, and selectable 2wd/4wd transfer case starting at $40,000.00.
The Duramax Engine
The Duramax engine is a 6600 Diesel V8, not to mention
one of the most powerful in its line. Rated at 300HP at 3100 RPM and
520 lb.-ft. of torque at 1800 RPM stock, it is able to produce up to
800HP and 1400 lb.-ft. of torque by Teaka Truck's diesel engineers.
With a case hardened block, one-piece aluminum crankcase, and one-piece
aluminum bell-housing to help reduce noise, vibration, and harshness,
don't be surprised if it outperforms your expectations.

Allison Transmission
Precise, efficient, smoother, and faster shifting is
what the Allison Transmission is all about. An advanced system of
electronic communication between itself and your engine gives you a
fully automatic and durable transmission. This is the ideal
transmission to mount up to the 6.6L Duramax diesel engine. Some
features include Grade Braking which gives you more control while
driving down-hill, Adaptive Shift Control which learns how you're
currently driving and changes it's shifting pattern to match, and a
Fuel Economy System which shifts at just the right time for optimum
efficiency.
