Choosing between the Kraton 6S vs Infraction 3S for your first RC car is a real struggle. Both have legendary reputations, but they’re built for totally different styles of bashing. If you’re after wild jumps, dirt, and monster crashes, the Kraton 6S EXB is hard to beat. If you want parking lot drifts and raw speed, the Infraction 3S is a blast. By the end of this guide, you’ll know exactly which one fits your driving style, upgrade ambitions, and budget for 2026.
Kraton 6S EXB, The Off-Road Bash King
The Kraton 6S EXB is designed for hard bashing on dirt, grass, gravel, and even rough terrain. It’s built around a 1/8 scale chassis, weighing 5.3 kg (11.7 lbs) without batteries. This latest EXB version ditches plastic diffs for full metal, giving you real durability where it counts.
Out of the box, the EXB is a roller, so you’ll need to add your own electronics. Most bashers pair it with a 2050Kv brushless motor, a 150A ESC, and 6S (22.2V) LiPo packs. With this setup and stock 12T pinion, you’re looking at 55+ mph on grass, sometimes breaking 60 mph on pavement. The center diff comes with 20 million cst fluid, so ballooning is minimal even on big jumps.
You get 7” (178mm) dBoots COPPERHEAD 2 tires, a 320mm wheelbase, and 47mm ground clearance. The EXB chassis is 7075-T6 aluminum, reinforced with EXB tower-to-tower braces. It takes direct hits and cartwheels that would snap weaker chassis in half. We’ve sent ours 12 feet in the air, landed straight on concrete, and kept bashing with nothing but a bent hinge pin.
The real appeal is how the EXB handles punishment. The bulkhead design is vastly improved over the V4, making diff swaps easier and less prone to stripping. Suspension arms are thick, and the shock towers won’t bend unless you’re truly reckless. There’s a reason you see more Kratons than any other 6S truck at the local dirt track.
On dirt, the Kraton’s layout gives you just enough agility for quick direction changes, but it’s stable at speed. On pavement, it’s a beast, though you’ll see some tire ballooning over 50 mph unless you upgrade to belted options. And yes, you can run it as a street basher, but honestly, the Kraton is happiest when it’s flying over jumps or tearing up loose ground.

Infraction 3S, The Street Speed Demon
The Infraction 3S is made for tarmac, concrete, and smooth parking lots. It’s 1/8 scale, but runs lighter at 3.85 kg (8.5 lbs) with battery, and sits lower to the ground. Unlike the EXB, the Infraction 3S comes RTR with a Spektrum 3200Kv brushless motor and 100A ESC installed.
This platform is all about controlled slides and high-speed runs. On a 3S (11.1V) LiPo, you can hit 50+ mph out of the box with the optional speed gear installed. The stock pinion is 20T, but swap in the 26T gear and you’ll see the claimed 55+ mph, just watch your temps and motor health.
The 83mm (3.27”) Hoons tires give insane grip on asphalt, and the AWD layout lets you drift, donut, or straight-line race without much setup. The Infraction 3S body is aerodynamic, with functional splitters and air dams that actually help plant the car at speed. Shock oil is tuned firm, so there’s little roll, perfect for aggressive cornering but punishing on potholes or uneven surfaces.
Durability is solid for a street rod, but you can’t huck it off a BMX ramp and expect it to survive. The front splitter is a known weak spot, and chassis scrapes are part of the deal if you drive low. Body posts need regular checking, and Hoons tires can vanish in a single session if you like donuts. Parts are widely available, but you’ll go through suspension arms and front lips if you bash as hard as you would with a Kraton.
This is the ARRMA for folks who want to rip parking lots at dusk, drag race their friends, or learn to control a slide at 40 mph. It’s also quieter than the 6S Kraton, making it more neighbor-friendly for after-dinner runs. If you crave street speed, the Infraction 3S delivers a rush that off-road bashers just can’t match.

Key Differences That Actually Matter
The Kraton 6S EXB and Infraction 3S aren’t just for different surfaces, their design DNA diverges at every level. The Kraton is built to take abuse, while the Infraction is a precision street machine. Let’s break down the differences that’ll make or break your first RC decision.
1. Power System and Voltage: The Kraton 6S EXB expects twin 3S or one 6S LiPo (up to 22.2V), while the Infraction 3S uses a single 3S (11.1V). That means the Kraton is running nearly double the voltage, which translates to more torque and bigger stunts, but also more expensive electronics and batteries. The Infraction’s 3200Kv motor and 100A ESC can’t take 4S, so you’re capped at 3S speeds without major mods.
2. Chassis and Suspension: The EXB’s 7075-T6 aluminum chassis, beefy arms, and tower-to-tower braces are designed for impacts. The Infraction runs a flat street chassis with firm shocks, lower ground clearance (about 15mm), and minimal flex. You can land the Kraton nose-first off a 10-foot jump and maybe lose a body clip. Try that with the Infraction, and you’ll be replacing the splitter and maybe the chassis plate.
3. Out-of-the-Box Experience: The Infraction 3S comes ready-to-run, including Spektrum radio gear. The Kraton 6S EXB is a roller, you have to supply your own motor, ESC, radio, servo, and batteries. That’s more work, but also lets you pick top-tier electronics from the start. For true beginners, the Infraction’s simplicity is a big plus.
4. Wheels, Tires, and Handling: 178mm dBoots on the Kraton vs 83mm Hoons on the Infraction. The Kraton’s tires absorb rocks, roots, and landings. The Hoons are sticky, but wear fast and won’t survive off-road. The Infraction’s firm suspension makes it a joy to drift, but every bump feels harsher than on the plush Kraton.
5. Maintenance and Failure Points: The Kraton’s notorious weak links, rear diff outdrives, shock rod ends, and sometimes center driveshafts, usually show up after big landings or repeated cartwheels. Infraction owners deal with splitter and tire wear, and eventually, spur gear stripping if you try to run 4S. Both have strong aftermarket support, but the Kraton’s modular diff design makes repairs faster.
6. Upgrade Path: The EXB is ready for extreme mods: monster servos, 8S motors, steel spur conversions. The Infraction maxes out around 4S with significant upgrades and cooling, but the chassis can’t take the weight or torque of bigger power reliably. If you love wrenching and customizing, the Kraton gives you more room to grow.
7. Price and Running Costs: As of 2026, the Kraton 6S EXB roller is around $450–$500, plus $250–$350 for electronics and $120–$200 for a good 6S LiPo. The Infraction 3S is $320–$350 RTR, with a decent 3S LiPo running $60–$90. Tires for the Kraton are $60–$80/pair, Hoons for the Infraction are $30–$40/set but wear out much faster if you love burnouts.
8. Real-World Versatility: The Kraton can bash almost anywhere, dirt, grass, skateparks, even snow with the right tires. The Infraction is a tarmac specialist; it struggles on even short grass and can’t handle gravel or bumps.

Terrain, Real-World Performance, and Bashing Scenarios
The Kraton 6S EXB dominates almost any surface. We’ve run it on baseball fields, rocky trails, snow, and even sand dunes. The weight and 6S torque let you blast through thick grass or launch off homemade ramps without a second thought. Even after 50-foot cartwheels, the EXB keeps going, though you’ll want to check for bent drive shafts or popped rod ends after a hard session.
Water-resistant electronics and sealed diffs mean mud and puddles aren’t a worry. Our group’s Kratons routinely survive full submersion, though you’ll want to dry bearings and re-grease the diffs after. The only real limitation is tire ballooning at high speeds, but swapping to belted tires or running a center diff with stiffer fluid helps a lot.
Where the Kraton falls short is pure speed control on tarmac. It’ll spin all four tires and fishtail on acceleration, even with punch settings dialed down. That’s where the Infraction 3S shines. With its low ride height and street-specific Hoons, the Infraction lays down power cleanly. Controlled slides are easy, and you can reliably hit 50+ mph in a big open lot. Try that on grass, though, and you’ll get stuck almost instantly.
For jumps and stunts, the Kraton is in a different league. You can hit BMX ramps, skatepark bowls, or backyard dirt mounds. The Infraction doesn’t jump, it’ll nosedive and break bodywork if you try. But for parking lot races, drag launches, and learning throttle control, the Infraction 3S is a more forgiving teacher. It’s easier to track straight, far less likely to flip, and less intimidating for new drivers at speed.
Both require maintenance after hard use. With the Kraton, expect to replace shock rod ends and driveshaft pins regularly. Infraction owners should keep spare splitters and tire sets handy. For both, a quality LiPo charger and reliable batteries are must-haves for safe running.
→ LiPo Balance Charger, Fast, accurate balancing is the key to long battery life and safe charging, especially with big 6S packs.
→ 6S LiPo Battery, A quality 5000mAh 6S pack is the Kraton’s lifeblood, giving 15–20 minutes of real bashing per charge.
Who Should Buy Each? Your First ARRMA Basher Decision
If you’re brand new, here’s the short version: The Kraton 6S EXB is for those who want to bash hard, hit jumps, and aren’t afraid to wrench a little. The Infraction 3S is for speed junkies who love smooth surfaces and RTR simplicity.
Pick the Kraton if you have space for off-road runs, enjoy building or upgrading, or want a truck that can survive gnarly crashes. Be ready to invest in electronics, a decent charger, and durable servos, all costs that add up fast. The learning curve is steeper, but you’ll grow into the platform, and upgrades are endless.
If your playground is parking lots, empty streets, or you want to slide and drift, the Infraction 3S is the better entry point. It’s less intimidating for first-timers, with predictable handling under throttle and fewer out-of-the-box surprises. Maintenance is lighter, electronics are pre-installed, and you’ll be driving 10 minutes after unboxing. For those who want to mod, aftermarket support for the Infraction 3S has grown every year, but high-voltage upgrades are limited by the chassis and ESC.
One tip: think about your local conditions and where you’ll actually drive. If you only have grass or dirt, the Infraction will frustrate you. If you’re in an urban area with nowhere to jump, the Kraton might never see its full potential. The right first ARRMA is the one you’ll use the most, not just the one with the highest specs online.
