Where to Find and Actually Use the Arrma Kraton 6s EXB Parts Diagram
The Arrma Kraton 6s EXB Parts Diagram is the exploded-view reference sheet that maps every individual component of the vehicle to its stock part number. It lives on Arrma's website under the support section for that model. You open it, you look up the part you need, you order it. The diagram itself is just a PDF. Getting what you actually need out of it requires knowing how Arrma numbers things, which is where most people hit a wall. I spent about two years running the EXB at the track before I stopped guessing at part numbers. The first rule is simple: the diagram on Arrma's site is accurate for the version that shipped with your specific batch, but it changes. I found this out after a front upper arm broke during a race and ordered the replacement using the diagram number. The package arrived, the arms fit, but the mounting hole pattern was slightly different from what I had before. Turns out Arrma updated the part during a mid-production revision and didn't update the diagram to reflect that the old and new versions are not interchangeable on the knuckles. I had to go back, return the first set, and wait a week for the correct revision. The fix was pulling the serial number from the motor controller sticker and cross-referencing it with the date code on the parts diagram to confirm which revision I owned.
How to Read the Arrma Kraton 6s Exb Parts Diagram
The diagram is organized into groups: suspension, drivetrain, electronics bay, body, wheels, and hardware. Each group has a numbered list of components with a corresponding exploded view illustration. The key column is the Part Number column. That number is what you type into the Arrma parts order form. The Description column tells you roughly what it is, but the description is sometimes vague. "Front Upper Arm Assembly" could mean the whole assembled piece or just the individual arm depending on the context. Always check whether the line item says " Assy" or not. If it says " Assy" it means the assembly including bushings and hardware. If it doesn't, it is the bare component. The hardware section is its own separate category. This is where people make mistakes. The diagram lists M3x8mm screws and M4x10mm screws alongside the mechanical parts, but those are often sold in bulk packs rather than individually. If you need two of something, buying the bulk pack is usually cheaper and gets you the exact same fastener. I learned this the hard way when I needed four hex head screws for the motor mount. Buying them individually through the parts diagram cost me over eight dollars. A single bulk pack of mixed M3 and M4 hex screws from Arrma costs six and gives me more than I needed for a year. The electronics bay section is relatively small. The EXB runs a 6S setup with a 1550KV brushless motor, a 120A ESC, and a 6S LiPo. The diagram will list the ESC, the servo, the receiver, the battery strap, and the wiring harness. None of those typically wear out unless you crash hard enough to crack the ESC housing or snap the servo output gear. The realistic failure points on this model are the wheel hubs, the C-hubs, the differential gears, and the drive shaft couplers. The parts diagram covers all of these, but the ones that actually break are the first ones you should bookmark.
Common Pitfalls When Ordering From the Diagram
The biggest issue is revision drift. Arrma makes incremental updates to suspension geometry, gear ratios, and electronic placement across a model's life cycle. The parts diagram you see online may not match the exact configuration of the truck in your garage. The only reliable way to verify is the serial number on your vehicle. It is usually a sticker on the battery tray or inside the electronics bay. You enter that serial number into Arrma's parts lookup and it filters the diagram to your specific revision. Without that step you risk ordering parts that look right but don't physically mate with your existing components. Another problem is sub-assembly confusion. Some items in the diagram are sold as complete assemblies while the individual components within them are not available separately. The front hub assembly, for example, includes the hub, bearings, and locknuts as one part number. If just the bearing goes bad, you still have to buy the entire hub assembly unless Arrma has released a separate bearing SKU for that revision. I found this out when a bearing pitted after a water crossing. I ordered the hub assembly, took apart the old one, swapped the bearing, and then realized the new assembly came with bearings already pressed in. I had two good hubs and one disassembled hub. The workaround was simpler than I expected. I just removed the bearings from the new assembly and put them in the old hub. The parts diagram doesn't flag this kind of situation, so you learn by experience. Tire compound numbers are another thing the diagram doesn't explain well. The EXB comes with foam inserts and rubber tires. The parts diagram lists the tire as one part and the foam insert as another. But the rubber tire compound varies by color and formulation, and Arrma sometimes swaps compounds between production runs without changing the part number. If you are ordering replacement tires for competitive running and the grip level matters, do not assume the new batch will feel identical to the old one. Get a sample first or buy from someone who has run the current batch.

What the Diagram Won't Tell You
The parts diagram shows stock configuration only. It does not account for aftermarket upgrades or modification kits. If you have installed a steering upgrade, a different gear set, or a reinforced suspension kit, those parts will not appear in the official diagram. The diagram is a reference for stock rebuilds, not for modified builds. I keep a personal spreadsheet alongside the diagram that tracks every non-OEM part I have installed and the equivalent stock part number if one exists. This saves time when I need to order a replacement for something I modified two years ago. Without that tracking system, you are left guessing which aftermarket part maps to which stock position. The diagram also does not list torque specifications or assembly sequence. You will need to pull the build manual separately if you are doing a full teardown. The parts diagram and the build manual are two different documents on Arrma's site. One tells you what parts exist. The other tells you how they go together. Running both at the same time during a rebuild cuts down on frustration significantly. I usually have the diagram open in one tab and the manual in another, referencing each other as I work through the disassembly. One more practical note. The PDF version of the diagram is not always the most useful format. I print it on A3 paper if I can get it, because the detail on the suspension and drivetrain sections gets muddy at smaller sizes. If you are working late at night under garage lighting, a printed copy laid out on the bench is faster to reference than zooming in and out on a phone screen. This is a minor convenience that becomes important when you are trying to distinguish between two nearly identical screw lengths in the hardware section.
If you need the current official Arrma Kraton 6s EXB Parts Diagram, go to the Arrma support page for the Kraton 6S EXB and look for the parts diagram or exploded view PDF. Enter your serial number if the system prompts you. Cross-reference any revisions before ordering. And keep a record of your build state so you know whether what you are looking at in the diagram is actually what is installed on your truck.
