ALL UNLIMITED TROPHY
TRUCK CHASSIS BEGIN WITH
A CAD DESIGN. THIS ONE
FROM ARMADA ENGINEERING
SHOWS THE COMPLETED
CHASSIS, INNER BODY
PANELS, SUSPENSION AND
ENGINE TO PROPER SCALE.
TROPHY TRUCK BUILDERS
LIKE ARMADA ENGINEERING
USE PRECISION HIGH-QUALITY
WELDS AND CNC LASER CUT
STEEL TO CREATE A TT SPEC
CHASSIS.
A COMPLETED WELDED
ARMADA ENGINEERING
CHASSIS IS A WORK OF ART
IN ITSELF. BUT IT'S ALSO
ENGINEERED TO BE STRONG
AND PROVIDE SAFETY FOR
THE PASSENGERS.
TT Spec vehicles use 37-inch race
tires on 17-inch wheels while a
majority of Unlimited Trophy Trucks
use 39-inch tires on 17-inch wheels.
The fiberglass or carbon fiber OEM
production body panels look the
same. Although the use of a Turbo
400 transmission is required in TT
Spec class, many Unlimited Trophy
Truck teams use the same thing
even though they are not restricted
to using a Turbo 400 only. The
suspension travel is generally the
same 26-inches of wheel travel on
the front A-arms, and 30+ inches
of wheel travel on the rear four-
link, trailing arm suspension.
TT Spec Engine
Restrictions
The major difference in the
Trophy Truck Spec versus Unlimited
Trophy Truck is sitting in the engine
bay. The TT Spec is limited to a
stock, factory engine from 2008
or newer model years. There is
a maximum engine size of 376
cubic-inches (or 6.2-Liters). The
factory engine control unit (ECU)
must be used. No modifications
to the crate engine is permitted.
That means no porting or polishing,
balancing or blueprinting…nothing.
