A truly impressive beast of a truck, the 6900 TwinSteer is a marvel of oversized engineering. Built on a massive four-axle chassis, its intended purpose is logistical support for the oil and gas industries. Despite the fact that the TwinSteer lacks AWD functionality, its sheer size and its engine's excessive torque result in a vehicle that is capable of traversing harsh terrain by simply plowing its way through.
A very sturdy gearbox optimized for harsh off-road conditions, sacrificing fuel efficiency, top speed and gear count in exchange for three Low Gear stages.
A thoroughly improved engine variant offering additional protection from physical hazards, as well as improved power output and acceleration.
A high-range gearbox variant with increased gear count and top speed, and an additional High Gear at the cost of lower durability.
A raised suspension kit, good for venturing down old roads or off-road terrain.
The apex predator of its class, this engine unit offers further increases in power, acceleration and reliability under stress at the cost of higher fuel consumption.
An all-wheel drive powertrain that can provide torque to all connected wheels on-demand.
A specialized gearbox allowing free Low Gear / R Gear transfer ratio tuning. Notoriously fragile and not very fuel-efficient in AWD mode owing to its mechanical complexity.
