Overview
“Designed Fast, Designed Tough” may be an understatement when describing the KRATON® Extreme Bash Roller Monster Truck. Made of strong anodized 7075 T6 aluminum, the laser-etched chassis plate gains further rigidity from the use of front and rear aluminum chassis braces. Strong composite chassis side pods and a center body support and brace provide more rugged resilience.

Durable steel driveshafts plus all-metal diff outdrives and gearbox internals keep the heavy-duty 4-wheel drivetrain rolling over punishing tracks. An Extreme Bash toughened suspension system smooths the ride, with a steel rear suspension mount and adjustable oil-filled shocks mounted on 7075 T6 anodized aluminum front and rear shock towers.

The KRATON Extreme Bash Roller Monster Truck’s list of EXB components also includes the following and more to give this big machine uncompromising muscle:

EXB Heavy-duty front and rear arms with aluminum strengthening cap
EXB Heavy-duty steel turnbuckles
EXB Heavy-duty front upper steel hinge pins
EXB Plated limited-slip differentials
EXB Red-anodized aluminum servo mount
EXB Large volume waterproof receiver box
EXB Front bumper

Its aggressive dBoots® Copperhead 2 tires arrive mounted on multi-spoke wheels with durable hubs to deliver all-terrain traction assisted by a high downforce wing that adds an aggressive edge to the look of the exclusive EXB matte and gloss effect finished truck body.
