- Impact-Absorbing Front Bumper — The redesigned front bumper features shock-absorbing geometry that dissipates impact energy during high-speed collisions, protecting the chassis and reducing component damage from aggressive bashing.
- Multi-Structured Centre Brace System — Featuring anodised 7075-T6 aluminium with laser etching, the reinforced 5mm chassis plate includes strong composite chassis side pods and centre body support, delivering maximum structural rigidity for aggressive driving.
- Water-Resistant Design — The sealed electronics module and waterproof servo protection allow confident operation in wet conditions and muddy terrain, though full submersion should be avoided to preserve component longevity.
Technical Performance
The ARRMA KRATON 8S EXB represents a significant engineering achievement in large-scale RC monster truck design. Powered by the new Spektrum FIRMA 1100Kv brushless motor, this truck achieves a top speed exceeding 50 mph (80 kmh), making it genuinely competitive for high-speed bashing and track racing. The motor's 10% torque increase over the previous model translates to measurably superior acceleration and hill-climbing ability, whilst the 8S LiPo compatibility opens the door to massive performance potential without sacrificing longevity or reliability. The 160A V2 Smart ESC manages this power with sophisticated current limiting and thermal management, protecting components whilst delivering responsive throttle control. The 9.06:1 gear ratio provides an excellent balance between acceleration and top speed. Constructed from premium 7075-T6 aluminium with CNC machining and laser etching, the chassis plate measures 5mm thick — significantly thicker than competitor offerings — providing genuine structural advantage during impacts. Independent suspension geometry with 20mm bore oil-filled shocks and ultra-thick composite towers absorbs enormous impacts whilst the dBoots COPPERHEAD 2 big block tyres provide consistent all-terrain grip. The four-wheel-drive system features 3-gear differentials, all-metal outdrives, and steel driveshafts that provide reliable, predictable handling characteristics. At 771mm in length, 602mm in width, and 282mm in height with a 491mm wheelbase, the truck possesses imposing proportions ideal for bashing larger terrain. The comprehensive waterproofing of the electronics module and S6510 servo ensures genuine weather resistance for UK's variable conditions. With complete ball bearings throughout, the KRATON 8S EXB demands minimal maintenance whilst delivering consistent performance session after session.

Frequently Asked Questions
- What is the top speed of the ARRMA KRATON 8S EXB? — The truck achieves a top speed exceeding 50 mph (approximately 80 kmh) depending on battery configuration, terrain conditions, and driving technique. The 8S configuration with optimal gearing delivers genuinely impressive acceleration and sustained high-speed performance.
- Is this suitable for beginners? — The KRATON 8S EXB is classified as Skill Level 5, meaning it is designed for experienced RC operators with knowledge of brushless systems, LiPo battery handling, and maintenance. Beginners should first gain experience with smaller-scale models before progressing to this high-performance machine. The integrated AVC technology does provide stability assistance, but this is still a serious performance vehicle requiring respect and experience.
- What battery does the KRATON 8S EXB need? — This ready-to-run truck requires either two 3S or two 4S LiPo batteries with EC5 or IC5 connectors. The 8S configuration (using two 4S packs) delivers maximum performance, whilst the 6S configuration (using two 3S packs) provides a more moderate power level. Both configurations are fully supported by the included ESC and motor.
- What makes the EXB version different from standard KRATON models? — The EXB (EXtreme Bash) designation indicates comprehensive strengthening throughout the chassis. Key differences include the 5mm thick laser-etched 7075-T6 aluminium chassis plate (versus standard thickness), red-anodised CNC aluminium front brace mount, impact-absorbing front bumper design, and 8mm thick steel rear turnbuckles plus 7mm thick steel steering turnbuckles. Additionally, the new EXB colour scheme features an aggressive matte and gloss finish distinct from previous KRATON models.
- How long does the battery last per charge? — Runtime depends on driving style, terrain, and battery capacity. Typical bashing sessions run 15-25 minutes per battery pack depending on acceleration and throttle usage. Using higher capacity batteries extends runtime proportionally.
- What charger should I purchase for this truck? — Spektrum Smart chargers like the S2200 G2 AC 2x200W Smart Charger offer excellent compatibility and integrated telemetry. Alternative quality chargers supporting LiPo batteries with appropriate current ratings (minimum 10A for standard packs) work equally well. Avoid cheap unbranded chargers that lack proper LiPo safety protocols.
- Can I use this truck in wet conditions? — The water-resistant electronics module and waterproof servo allow confident operation in wet grass, muddy tracks, and rain. However, full submersion should be avoided, and electronics should be dried following wet use to maintain longevity.
- What maintenance does the KRATON 8S EXB require? — ARRMA designed the truck with easy maintenance in mind. Regular cleaning after muddy sessions, periodic checking of turnbuckles and bolts for tightness, and occasional shock fluid top-ups are standard maintenance. The easy-access 3-bolt motor mount allows quick replacement or inspection. Most users find annual bearing replacement unnecessary with proper care.
- Is the radio system included? — Yes, the Spektrum DX3 2.4GHz radio, SR6200A receiver with AVC, and all installation hardware are included in the ready-to-run package. No additional radio equipment is necessary.
- Does this come fully assembled? — Yes, this is a ready-to-run (RTR) model arriving completely assembled with all electronics installed and tested. Simply add batteries and AA transmitter batteries, and you're ready to bash.
