Arrma Kraton 6S vs Traxxas X-Maxx: which giant basher should you buy?

They get compared constantly, but they aren't the same class of truck. One is a fast 1/8 speed truck, the other a much larger 8S monster. Here's how to choose, and what each really costs to run.

How we pick Updated · We earn a commission when you buy through our Amazon links.

Buy the Arrma Kraton 6S if you want speed, durability and a lower total cost; buy the Traxxas X-Maxx if you want the biggest, most dramatic truck for wheelies and huge jumps and you're ready to pay for it. They're not true rivals: the Kraton 6S is a 1/8-scale speed monster truck, while the X-Maxx is a giant 8S truck. If you want a fair fight, compare the Kraton 6S with the Traxxas Sledge, and the X-Maxx with the Arrma Kraton 8S. We cover all four below.

How we compared them

We pulled each truck's current Amazon listing on October 3, 2026 and compared what the manufacturers state: motor and ESC, top-speed claim, scale, factory upgrades and what's in the box. Durability and handling notes reflect owner consensus on brand forums and retailer comparisons, labeled as such. We didn't drive or crash these trucks ourselves.

This is a How we pick comparison. Speeds are manufacturer claims, not our measurements. How we research.

Why this matchup is lopsided

The Kraton 6S and X-Maxx get compared because they're each brand's famous big basher. But Traxxas and Arrma both sell a truck in each class:

The four trucks, and who each is for

Best for speed and durability per dollar

Arrma Kraton 6S BLX V6

The Kraton 6S is the truck forum regulars recommend when someone asks for a basher that survives abuse. The V6 ships with EXB parts and a clipless body, and Arrma explicitly designs it to run on 4S for "fun and manageable" driving before you install 6S. Its long, low speed-truck stance is more planted at speed than a tall monster truck.

  • Scale1/8
  • Power6S BLX brushless (4S capable)
  • Max speed listed65 mph
  • PartsEXB Extreme Bash
  • Bodyclipless, taller composite side guards
  • Battery/chargernot included

Why it stands out

  • Lower price and cheaper parts than the X-Maxx
  • 4S mode for learning, 6S for full speed
  • Strong owner reputation for durability

Think twice if

  • You want wheelies and backflips: the X-Maxx is the better stunt truck
  • You want parts from a local shop the same day

Traxxas X-Maxx Ultimate 8S

The X-Maxx is about spectacle. Traxxas's Ultimate edition adds machined aluminum caster blocks, steering blocks and hub carriers, steel CV driveshafts and hardened gears, and its self-righting feature lets the truck flip itself over. Traxxas says the 1200XL motor turns 30+ volts into "wheel-standing acceleration." If you want huge air and endless wheelies, this is the truck.

Traxxas Sledge 6S

If you want Traxxas but the X-Maxx is too much truck, the Sledge is the 1/8-scale 6S basher built to compete with the Kraton. Traxxas lists a "proper 6s driveline with bigger gears and more steel", a triangulated aluminum chassis and belted tires that hold their shape at speed.

Arrma Kraton 8S BLX

Arrma's giant is the Kraton 8S, a 1/5-scale speed monster truck loaded with EXB 7075-T6 aluminum parts. Like the 6S, it's a lower, longer speed truck rather than a stunt-focused monster, so it suits fast runs across big open spaces more than wheelies.

How they drive: speed truck vs monster truck

The shape of each truck tells you how it behaves. The Kraton is a "speed monster truck": long, wide and relatively low. That layout keeps it planted when you're running flat out across a field and makes it less likely to traction-roll in a fast corner. Owners who compare the two typically describe the Kraton as the more stable truck at speed and quicker through turns.

The X-Maxx is a tall, heavy monster truck on enormous tires. It soaks up rough ground, lands big jumps with a slow, dramatic bounce, and lifts its nose into wheelies on demand. Traxxas leans into that with self-righting and TSM, which helps keep the truck pointed straight when the tires are spinning on loose dirt. It's the more playful truck; the Kraton is the faster one.

Size also affects where you can drive. A truck the size of the X-Maxx needs a big, empty space, and transporting it takes most of a car's trunk. The 1/8 Kraton is still large, but it's easier to store, carry and find room for.

Running costs: the part most comparisons skip

Neither truck includes batteries or a charger, and big trucks need big packs. Budget for them before you choose:

  • X-Maxx 8S: two 4S LiPo packs per run, plus a charger that can handle them. Traxxas iD packs and chargers recognize each other automatically; the Traxxas EZ-Peak Live Dual 200W charges two packs at once.
  • Kraton 6S: 6S worth of LiPo (Arrma also lets you start on 4S), with connectors that match your truck. Packs like this 4S 6200 mAh pack with EC5 connector are sold for Arrma 1/8 trucks; confirm the plug on your model before buying.

Big trucks mean big packs, and big packs demand careful charging and storage.

Safety with large packs: follow the manufacturer rules every time. Charge in a fire-resistant container such as a LiPo bag, on a non-flammable surface, never unattended and never overnight; use a balance charger set to the correct cell count; and store packs at about half charge with your charger's storage mode (Traxxas Battery Basics, Spektrum lithium battery safety). After a crash, unplug the battery and inspect it before charging again.

Parts are the other running cost. Bigger, heavier trucks put more energy into every crash, and X-Maxx-size parts cost more than 1/8 parts. Our first 5 upgrades guide covers what tends to break first.

How to choose

Choose the Kraton 6S if

  • You want the most speed and toughness for your money.
  • You want to learn on 4S before going to 6S.
  • You drive fast runs in parks, fields and BMX tracks.

Choose the X-Maxx if

  • You want the biggest, most attention-grabbing truck at the park.
  • You care more about wheelies, flips and big air than top speed.
  • You already own Traxxas iD packs and chargers.

Choose neither if

This is your first hobby-grade truck and you don't have a large private space to drive. Start smaller with something from our best RC car for beginners list; both brands sell excellent 2S and 3S trucks.

Space is the real requirement. Trucks this size need large, empty areas away from people, pets and traffic.

The bottom line

For most buyers, the Arrma Kraton 6S V6 is the smarter purchase: it's faster on paper, tougher by reputation and much cheaper to buy and run. The Traxxas X-Maxx Ultimate is the one to buy for sheer size and stunts. And if you want an apples-to-apples choice, compare the Kraton 6S with the Traxxas Sledge, or the X-Maxx with the Arrma Kraton 8S.

Questions people ask

Is the Kraton 6S faster than the X-Maxx?
On paper, yes. Arrma lists the Kraton 6S V6 at 65 mph and Traxxas lists the X-Maxx Ultimate at 50+ mph. The X-Maxx is a much larger, heavier truck built for wheelies and big air rather than top speed. Real speeds depend on batteries, gearing and surface.
Which is more durable, Kraton 6S or X-Maxx?
Owners rate both as very tough for their size. The Kraton 6S V6 ships with Arrma's EXB (Extreme Bash) parts, and the X-Maxx Ultimate ships with machined aluminum and hardened steel driveline upgrades. Bigger trucks hit harder, so X-Maxx parts tend to cost more when they do break.
What is the Traxxas equivalent of the Kraton 6S?
The Traxxas Sledge. It's a 1/8-scale 6S monster truck with an aluminum chassis, a 2000 Kv motor and a 70+ mph claim, so it lines up much more closely with the Kraton 6S than the X-Maxx does.
What is the Arrma equivalent of the X-Maxx?
The Arrma Kraton 8S, a 1/5-scale speed monster truck that runs 8S LiPo power. It and the X-Maxx are the giant trucks of each brand.
Can a beginner drive a Kraton 6S or X-Maxx?
It's possible, but neither is a good first truck. Both are heavy and fast enough to injure people or damage property. If you start with one, use the Kraton's 4S option or any reduced-power mode your radio offers, drive in large empty spaces, and keep bystanders well away.
What batteries does the X-Maxx need?
The X-Maxx 8S runs on 8S LiPo power, normally two 4S packs. Traxxas's own iD packs plug straight in and are recognized by Traxxas iD chargers. Large packs like these need the full LiPo safety routine: fire-safe charging, never unattended, and storage voltage between sessions.
