USA-1 Monster Kruiser GP 1/8th 4WD

Built on a pickup truck chassis, large diameter tires and big engines with massive horsepower were installed by fun-loving American off-roaders to create the monster truck. These ever-popular monster trucks can be seen on specially-made racing circuits or jumping rows of cars in stadiums across the USA. Many R/C monster truck models have been produced over the years. First among equals is the legendary 1/8 scale USA-1 that embodied the might of American trucking power during the 1980's and 90's. Officially licensed by Kyosho in the 1990's, the R/C model uniquely captured the power and glory of the USA-1. Now it's 'comeback-time' for the USA-1, with modern chassis and drivetrain technology, upgrades unique to the USA-1 throughout, and a newly-designed 'ULTRA SCALE BODY' with form and detail finished to display-model standards. The iconic American flag graphic emblazoned on the body makes your heart swell with pride! The chassis features shaft-driven 4WD and 5-link suspension based on the Mad Crusher 2.0 & FO-XX models. Most of the suspension components have been uniquely upgraded and reinforced for the USA-1 at each point to handle the powerful KE25SP2 engine, and the rigors of monster trucking. A 3-speed automatic transmission produces dynamic acceleration, which is enhanced by a true suspension system to produce "scale" running characteristics worthy of the prestigious USA-1, and make you feel like a monster truck driving god. Released as a pre-assembled Readyset, the USA-1 is almost ready for action straight out of the box.

The combination of the rigid frame with a shaft-driven 4WD system and five-link suspension is well-suited to handle the full grunt of the powerful engine, just like the original machine. This Readyset model comes with R/C system pre-installed.

Under license by USA-1, the polycarbonate body has been produced to a spectacular level of detail, with body size and tire ratio almost identical to that of the real USA-1. With separately molded accessory body parts including grille, carburetor, mirrors, roll cage, chassis-mounted front bumper, and a removable 5-series fog light row on the roof, the spirit and legend of the USA-1 is captured in all its glory.

Molded and chrome-plated triple carburetors look identical to those used on the real truck, which looks awesome sticking through the hood once the body is attached. Coupled with the growl of the powerful engine, this accessory creates even more original details of the USA-1 more than ever.

Equipped with a KE25SP2 engine, the easier-to-adjust low-speed needle makes it easier to produce more power than the previous KE25SP engine. The engine is fitted with a pull starter so a starter box isn't required, and engine settings have been optimized at the factory.

The time-tested 3-speed automatic transmission effectively utilizes the full power of the engine. In the low speed range, the torque of the engine is optimized by the ratio of first gear, while the 2nd gear covers the medium speed range where torque tends to be insufficient. Acceleration to maximum speed is achieved smoothly and efficiently.


Differentials in the front and rear axles are taken directly from a well-developed World Champion 1/8-scale off-road car, and are equipped with metal ring, pinion, and spider gears to handle the power of the 25-class (approx. 4.2cc) engine, all while managing the difference in rotation between the left and right tires during turns for smooth, stable driving characteristics and increased traction.

A 5-link suspension platform controls the rigid front and rear axles to minimize drive loss and deliver superior traction and handling over uneven and varying running surfaces. The large-capacity oil shocks reliably help to absorb the impacts from the running surface.

The reinforced axle housing thrives under high-power and rough road conditions while improving crash resistance. The scale aspects of the dynamic steering
