Arrma Kraton 8S EXB vs Traxxas X-Maxx 8SWhich Should You Buy?

Put the Arrma Kraton 8S EXB and the Traxxas X-Maxx 8S side by side and you're looking at roughly 45 combined pounds of RC fury. These are the two trucks that define the 1/5-scale 8S category, and choosing between them has sparked more forum arguments than any other comparison in the hobby.

The Kraton 8S EXB edges out the X-Maxx on straight-line speed at 55 mph versus 50 mph. That 5 mph gap is noticeable at full throttle. The Kraton achieves this despite weighing 24.2 lbs to the X-Maxx's 19.84 lbs, which means Arrma's motor and gearing setup is doing serious work. But that weight comes at a cost. The Kraton lands harder, puts more stress on suspension components, and requires more throttle management on jumps. The X-Maxx, being over 4 lbs lighter, floats better through the air and is more forgiving of poor launch angles.

The EXB designation on the Kraton matters. It stands for Extreme Bash, and the truck backs that up with strengthened chassis braces, heavier-duty diffs, and beefier drivetrain components compared to the standard Kraton 6S. The X-Maxx counters with its self-righting feature, which is really useful at this scale. Flipping a 20-lb truck by hand gets old fast, and the X-Maxx's ability to right itself with a button press is a quality-of-life feature that Arrma just can't match. Build quality on both is excellent, but they approach durability differently. The Kraton is built to absorb punishment through material strength. The X-Maxx is built to avoid damage through better weight distribution and that lighter overall mass.

Battery situation is nearly identical. Both run dual 4S packs, with the Kraton specifying 6500mAh and the X-Maxx calling for 6700mAh. Runtime is comparable at 15-20 minutes of hard bashing. The real battery conversation is about cost: running 8S means two large LiPo packs per session, and spares get expensive fast. Neither truck has an advantage here. Ground clearance is essentially tied at 3.35 inches for the Kraton and 3.38 for the X-Maxx.

Now the money question. The Kraton 8S EXB is premium priced. The X-Maxx 8S commands a premium price. That's price in Traxxas's pocket for the privilege of their ecosystem. And honestly, the Traxxas ecosystem has merit. Parts availability at local hobby shops, the Traxxas Link app for telemetry, and the self-righting feature are tangible benefits. But that savings buys a lot of spare parts for the Kraton. Arrma's online parts availability has improved dramatically, though Traxxas still wins the walk-into-a-shop-and-buy-it-today game.

Dimensions are close. The X-Maxx stretches slightly longer at 30.67 inches versus 29.33 for the Kraton, but the Kraton is wider at 22.24 inches compared to 21.77. Both trucks are enormous and will dominate any bash spot. Transport and storage are equally inconvenient for both.

Long-term cost of ownership slightly favors the Kraton. Its EXB-spec components are tougher out of the box, meaning fewer replacement parts in the first year of heavy bashing. The X-Maxx's lighter construction, while better for handling, means certain plastic components wear faster under equivalent abuse.
