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.
