The ARRMA Kraton 1/8 EXtreme Bash Roller 4WD Monster Truck is a rolling chassis kit that adds extra toughness everywhere it counts. This 1/8 scale chassis is the perfect platform for high-speed bashing over brutal terrain. It's fully assembled and ready to accept your choice of powerful electronics. Top off the KRATON Extreme Bash Roller Speed Monster Truck with the included, exclusive EXB matte and gloss finish body — and you're ready to bash without boundaries.

"Designed Fast, Designed Tough" may be an understatement when describing the KRATON Extreme Bash Roller Speed 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 Speed 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

Arrma Kraton 1/8 EXB EXtreme Bash Roller 4WD Monster Truck (Black)
So picked up this beast of a basher today, had it built at hobby town so all I had to do was pick up and go. Needless to say I’m extremely impressed, I’ve watched the preview videos of guys beating on these trucks but I needed to know first hand could it really take the punishment, so I set off immediately to the track and let her rip. I flat landed it on the roof like a pancake from 10 feet in the air no damage, I cart wheeled it hard a few times no damage took about 8 hard front nose dives on big jumps and finally after about 20 mins of pure abuse popped a dog bone out of the cup on the front left, no damage just a violent enough hit to pop it out. All and all 5 mins to fix and she’s back to full speed. I ran this thing hard, and it took ever bit of it and then some, usually I wouldn’t try to break a car I just spent 1200 to build, but it was like aroma was challenging me that I couldn’t break it, and the only other damage to note on the car other then the dog bone popping out was two nice indents in the body from the repeated noses into the ground. Great job armma you built a hell of a truck on this one.

Also thanks to the guys down at Hobbytown Santee,Ca for helping me pick out the right electronics to put in they held up well under all the abuse and a special thanks to Bradon ( hope I spelt that right) who built the truck for me while I was at work. Was a great job and truly do appreciate it.

Update: so I’ve found one problem with this truck, blew out the rear differential on it’s 3rd run, seems this is a common problem arising with this truck. Should have 3 shims in the differential not 2 and it’s causing a problem with the mesh. Other then that chassis is still straight as a board, everything else is still in great shape. Seems this was just a small over look in production.

Stay far away - at least for now! There is a known defect in this truck and it’s all over the internet. The rear differential is build incorrect from the factory and there are no spares right now. Just bought this and ran it for 10 minutes. Called Horizon and they said “sorry about that, I know there are no parts available so we can give you a $20 inconvenience fee”. And sit on an expensive paper weight for months?

Stay away unless you want a boat anchor.
